Acorns can actually be quite easily blanched for effectively free. You just need to smash them, put them in a bag and use the water you use to flush your toilet to blanch them! Either chuck the whole bag into your toilet tank (upper part of course!) or add a second flow-through tank to make the toilet as usable as it has been before while serving as an acorn wash for free! After a few days to a week they should be done, ready for preparing to eat.
Brilliant! Best wishes.
Nice :)
I really like this one , what a great idea. Out with the brick and in with a bag of acorns!
Oops I used the lower end I didn't read the whole comment as I just assumed it would be ok as it's a out side loo we don't use ( it has a small heater to stop it freazsing in winter )
A royal flush of an idea :) thanks!
Druids used to place the acorns in a net and leave them in a running stream for some days before consuming. Also bullrushes eat starch and are good for making alcohol. They also remove nitrates from the environment deposited by intensive cattle farming. Bullrushes are the answer for the Dutch farmers rather than removing their cows and taking their land in the name of nitrate reduction. Hope you are well Rob.
The problems the Dutch are having are about control not pollution aka the government wants to control the food supply in order to control people, starving people will sell their children to eat so asking anything less than that is a done deal.
nice post mate thank you for taking the time to make it - keep well yourself and cheers
You don't know anything about what the druids used to do. They left no records, and all we know about them was written by their enemies. Stop spreading lies.
@@slappy8941 Oral tradition.
@@slappy8941 Wow what a nasty little troll you are. Yes you are correct that they didn't write anything down however "Pliny the Elder" and Julius Caeser both did write about them. From what they wrote we infer that that consuming elements of the Oak tree was infact a sacred act. Try reading a book sometime ;)
I can almost see this future "Moonshiners" episode where they make "Acorn shine". 😁
lol - I am tempted!
if its for ethanol production would it matter if tannin is in the brew as it would be left behind after the distillation ?
if moon shine discard the first 150 mL of distillation as this is methanol.
One time while I I lived homeless outside I blanched acorns by putting shelled nuts in a grain bag, and suspending the bag from paracord into a flowing stream. The entire process took absolute ages.
In Dutch the word for squirrel is eekhoorn, pronounced as the English acorn. When you were talking about how to grind up acorns it sounded very cruel to me. Btw it's easier to get rid of the tannin just by putting them in water for a while. The squirrels do the same by putting them in the ground and retrieve them later.
Robert, I have to thank you for giving us videos that have meaning and value. Also, when I was a boy scout we would pick acorns and make pancakes out of them. These are the lightest tastiest and best body cakes one can eat. I wait each year for the dropped morales to grab and make pancakes. The trick is to get rid of the tannin acid by soaking the crushed white savory white meat. We would smash the white parts and put in a clean soak, Then you lay in a flowing stream for hours. Than you smash the meat again and soak.Forgot to say to remove the brown colored husk outside the nut which is not what you want. Hope I did not forget a step or two since this adventure was many years ago. Worked for us. Peace vf
cheers mate
I remember the video of acorn coffee Ash made for you fellows.
wow - that is an awesome memory mate!
As someone who loves iced tea to excess, I can assure you that Tannin is toxic. Maybe it's not dangerously so, but it is a spectacular emetic.
omg... I remember learning about the word 'emetic' when I was young the hard way. The field guide said it was an emetic and I didn't know the word. Do not NOT nibble on wild mustard roots unless you want to violently disgorge your upper alimentary canal... lol...
I've heard the word before but now I know for sure what it means thanks.
@@shannonwhite2214 It means it makes you throw up.
I've had some very good pancakes made from acorn flour (had a little wheat flour in there to help with binding as well but it was Mostly acorn). Just grind it fine and it does quite well.
I liked the taste so I can see that would be good
Can we take a moment to appreciate that an ancient white oak is not only a cool tree, it's shade, it's bread, its fuel and it ground foot print is literally the diameter of the trunk!
nice one mate - we definitely should do that - cheers
First i would like to thank Robert for producing such great videos. Collecting Acorns; more and more... I was using a mini forced fan/rocket stove to bake different materials (in a metal pipe).. (with small hole for exhaust) at high temperatures in order to try and make high conductive carbon, well... the acorn "caps" when dry make an excellent low resistance carbon, and also; (when burned) a Super fuel!! I call it almost orange colour heat ...
I believe that the word 'acorn ' is Anglo-Saxon and literally means 'Oak Corn'. Note that the the term 'Corn' means any type of 'seed' in English, wrongly used in North America only for Maize.
seems more factual and less poetic mate - lol
Yeah, corn in the USA generically refers only to what used to be known as 'Indian corn'. People just got lazy and stopped mentioning the Indian part, once eating "the food of the other people" stopped being a taboo, and it became a normal part of the colonial American diet. 'Maize' is the proper name of that crop.
Though that word maize comes from the Taino Indians that the Spanish wiped off the face of the earth, the term did survive in Spanish as 'maíz' (see the resemblance?), but it never actually became popular as such in the English colonies.
I like the French form 'maïs' best, as it is written unambiguously, and like how it's supposed to be pronounced. Considering that English prefers French forms of Latin words, I'm mildly surprised it didn't catch on in English, like how the similar word "naïve" did.
The bushcraft technique for leaching the tannins is to chop/crush the acorns, put them in a net bag and dump them in a stream for a few days.
My family did exactly that to feed Cattle, and it's what people did back in the day, using wicker baskets, in a stream for a few days, job done.
cheers mate
@@LOFIGSD do the tannins pollute the creek water and poison the water life such as fish, cray fish, frogs, etc?
@@brendastolecki4755 why would that be any different than any other natural leaves or detritus going in a river, you could cut all the trees down, to stop anything that falls off a tree going in water, but then there would be no oxygen, if you want to worry about things in water, I suggest roundup and nitrates etc, than a few acorns.
loved the way his face light up and belly laugh after eating the Acorns, so glad i stumbled upon this
channel, what a thought provoking thing of beauty it is, im binging at the moment, i can feel my constructive juices flowing, and the old cogs grinding,,what a blessing,,thanks for sharing,,bob&MrTao,xx
Enjoy tuning in and catching up with more knowledge you share and enjoy your sense of humor.. Cheers.
awesome cheers mate
Centuries ago, another popular method for leaching tannins from acorns was placing your acorns in a hessian sack, and then anchoring it into a river which was left for anything between 3/4 weeks and then collected at a later date. The acorns were then dried and crushed into a powder ready for baking. I tried it one on the river test with surprisingly good results, the river method apparently gives the acorn powder a preserved distinctive taste, I can't confirm that thought because I haven't tried any other methods...
Weeks sounds like a long time. There was a show once on Discovery I think called HillBilly Blood. Well the two stars were on an impromptu hike and came across a bunch of acorns and they smashed them and soaked them overnight and had improvised pancakes in the morning. Tannic acid is water soluble so moving water is going to take the tannins fairly quickly. I usually make cover scent from acorns and I throw the used acorns back out but realistically I could probably eat them as soon as they cool afterwards because I boil water then fill the water with fresh acorns and let it steep like tea until the water is as dark as I’m going to get it. The darker it gets the better it works. I had a deer walk upwind to my ladderstand when I sprayed my boots with acorn scent.
@@308dad8 You do realize that "reality" TV isn't real, don't you?
You must have Red Oak acorns. White Oak can be eaten raw, and taste good. Love everything you do!
Never mind, you're not using red oak. :) That will teach me to watch the video all the way before commenting.
lol - it's English oak mate -that's a bit bitter - not as bad as red oak thought
Holm oak is the one you want - has a lot less tannins than most other oaks
You have to fight off the wild animals to collect white oak acorns or beach nuts. I found some places near humans they avoid though. Nice treat.
@2:54 Haha! I don't know if it's true that our ancestors actually brined acorns in urine. But I will say, it's a plausible theory.
In my neck of the woods, there remain several communities of the Choctaw tribe. They actively continue their native customs and traditions, to include foods. Roasted venison with acorns is a FANTASTIC meal. I normally don't eat wild game, due to the musk. But the woman who prepared this particular dish shared her secret with me: Brine the meat and acorns in cold salted water for 24 - 48 hours. It leaches the musk from the meat, and also leaches the bitterness from the acorns.
I've not yet tried that technique for myself, so I can only quote her word. But I also have no sense that she misled me.
I am absolutely 100% jealous of your shop
30 acres , hundreds of Oak trees , I can make flour out of them , didn’t know I could use them for heat , always learning ,
I make acorn bread when I have energy and time to boil those numerous times. It tastes delicious. A cup of ground acorn, a couple of eggs and some baking powder. But it time consuming process. The technique you showed is brilliant, I'll definitely try it this winter. Thank you!
Definitely an improvement upon my great-grandmother's methodology, interesting, thank you Robert.
awesome mate x
Mr. Murray-Smith,
I do understand that the word 'brilliant' is so commonly used there that it may have lost it's impact.
Your ability to retrieve, combine and speak from a pool of both vast and deep knowledge and to then deliver it in a very palatable form is truly: brilliant.
Well said I agree..😎
I also agree. I love to watch BBC TV, UK Isles, Auzzie and NZ. We Americans have butchered and murdered the "English" language. I love "wellies". I have incorporated it into my life and encouraging it to my granddaughter.🥰
Awesome video and concept!
Glad you liked it!
The people I've seen use them as an emergency food (survival campers), shell them, then either boil them in water or put them in a stocking and put them in a creek to let the moving water slowly leech the tannins.
But crushing them or splitting them makes it leach much faster.
cheers mate
I want to try doing laundry in a river by leaving it in a net, have been meaning to do that for years.
A proper chemist, tasting your own product! Great Video 😊
lol - it was certainly fun mate
I use Acorns to heat my house... grind them up and pelletize them for a pellet stove... also good at keeping over night embers alight on a traditional wood stove.
funny, they look like pellets already
The ash from that must make great fertilizer.
@@Barskor1 Certainly... the ground material is the best medium for growing mushrooms in also..
@@TheKlink Yes, they are just a little too big for the auger but not far off... natures pellets!
nice one mate - cheers
Fantastic Information for us Foragers! As well as a great Chemistry lesson at the End!! Thank You!!
I am always happy when you enjoy a video Andrea
Just found your channel, and this is the third video that I have watched and I am majorly impressed!
Thank you so much, I look forward to making my way through the huge library of videos that you seem to add to all of the time.
So awesome!
Acorns!
They use vodka in a similar process with marijuana to extract oil. They use a blender to chop up marijuana/vodka, makes a tea, filter out the leaves, evaporate the water, and you are left with a concentrated oil they put on gummie bears.
cheers mate
Similarly, an abundant plant here in the south-eastern US (probably all over) known as pokeweed (Polk Salad once cooked) requires toxin removal preparation of multiple boils before eating. They are like mustard, collard or turnip greens when finished.
Pick early growh .ten fifteen inches tall boil once .drain rinse and cook with eggs
I do the hot water leaching method, I do five water changes. I use my commercial made wood gas stove. So the fuel used is very little and is found all around my wood splitting area. I then dry the nuts then roast them in the oven or in a saute pan till a nice dark brown. Then grind and sift them to make a wonderful acorn coffee.
Thanks for the valuable lesson. I've wanted to utilize acorns as food and had scrapped the mission for all of the stated difficulty. Problem solved. You rock.
Wow! Very interesting. You so fond the most amazing stuff.
Well done and thanks
This is so cool! We need to be making use of this. Thank you for more awesome information!
Very interesting video Robert. Love your energy in the teaching :)
outstanding love it well done love the rebrew circular method very cool thanks robert
cheers mate
Thank you for you time.
Excellent presentation.
That's Fantastic Murray! I've used your stong tea suggestions for tannin fixative flower petal water proof non toxic hair dye. Obviously bioplastic cross-linking is another possibility.
Do the oils come out in the Ethanol solution? If so they should easily be recovered for diesel, heating or cooking fuel.
With Bayer Chemicals killing our New Zealand Avocado industry, paying 3cents each, with exclusive supply contracts and it costing more to harvest than the 150quid per tonne they ate paying, the 6tons per hectare of oil you can get makes SVO biodiesel our only option. Since JabCinders has closed our only oil refinery. And diesel and petrol now over 12 bucks a gallon.
YIKES! Arden is a Schwabolyte so no wonder.
What I find interesting is this that for a "primitive" culture living off the land, this process would greatly increase their calorie availability and possibly give them a fuel source as well as a tanning industry.
I agree mate
This is terrific. Great job making it easy to understand.
This really is top class information. Well done for discovering this process, and thank you for sharing.
I really did think it was well worth the share mate
Thanks Chef Rob! To be a chemist in the kitchen give an other title! Now the real hard work start to the day we make it to "the Acorn butter with bacon and egg sandwish!" Jamii! 🥸
lol - my next door neighbour his a chef - perhaps I should see what he can come up with lol
I have only ever watched 3 of your videos all this morning, I'm ill with covid, you are so jolly you cheered me up and i learned some things, especially how to heat our home this winter and use acorns we are sitting on so many I the Sherwood forest, so I've been wondering about natural heat and food! THANK YOU XX
Superb advice in so many different ways. Current bio fuels just seem to use agricultural land thus reducing food, but this project covers every Avenue . I love the beer as a bonus. Thankyou, not all knowledge is so much fun.nb love your enthusiasm also.
if you press them you get oil its quite a high % per gram of raw material its similar to peanut oil the fuel first used in a diesel engine just press no need to do anything else more efficent if you heat it first but works well cold then a lot of the tannins come out in the oil you can ferment the left overs then distill and make alcohol and burn that too both petrol substitute and derv substitute from one plant nothing complicated needed
top advice mate - thank you for sharing I was wondering about the oil
@@ThinkingandTinkering apparently people use the oil for cooking (so you tube shows) I wonder what it tastes like
Uh, acorns have a bad taste... But they can be processed for food. During a war here, some people used it. I was young, can't remeber how.
@@tomislavruzicic3955 ground acorns was a coffee substitute!
Did I understand that correctly it's just a use of the waste?
You are a wealth of of knowledge, thank you for sharing!
cheers mate
Fascinating. This made me reflect on your video about oak gall ink and I was wondering if acorns contain tannin like Oak galls. So that answered my question. The next question is, how to use the tannin carbonate as a replacement for the oak gall? I imagine it’s pretty straightforward.
Thanks ! this is a great public service video ! The agroforestry community world wide will be very interested in how we can more easily get protein and starch (and beer!) more easily from trees.
Everything we could ever need, nature provides. Thanks always!
absolutely mate
True, design genius!!
Xx
It sure beats eating bugs which they seem to have planned for us.
for sure mate
I'm gonna try this next time I make wine, it's really easy and available
Salute!
nice! - let me know how you get on will you?
I think the tannins in acorns vary as to where the tree grows. On the family farm in the black down hills in Devon the trees acorns on the high ground are bitter as hell yet the ones from the lower ground are quite palatable and mild and all are English oaks . So the result may vary a little as to where the acorns come from.
You my friend are a super high value individual , when the SHTF
Very interesting. I knew about the cold method of rinsing the acorns over and over again. Now I know a new way. Thanks! Keep the videos coming!
cheers mate
Tannins can also be removed effectively by pressure cooking the material with a wood ash solution ( mainly potassium) followed by rapid depressurising by removing the weight . This causes an internal boiling causing the tannins and lignins to be removed rapidly as black solution. The potassium tannate will be valuable as a nutrient for plants as well I think.
I remember my granma make acorn bars. No one like those save from my family (they say even it's poor food) but after all one bar and it's you meal. It's actually very good energy food or even survival kit.
You are a joy to watch! x
Great video, inspiring! I've got a bunch of oak trees around my house here. Acorn vodka sounds like an interesting project :-D
fascinating.. and you are a joy..
yes I'd heard the bag in a river one..
and yes too the toilet cistern is the modern equivalent..
I hear people using it to soak and desalinate slated cod..
bacalhau being the most popular dish here in Portugal
I am part Cherokee, I have and do eat acorns I just leech them in the out flow from my pond and in the Water Closet supply tank. I make flatbread, how cakes and pancakes from them and use it as a flour extender
You left out the $64 question: How much bio-ethanol can you get from fermentation relative to what you need to use to remove the tannins?
That was my question as well
Seeing as you can reuse the vodka/ethanol any extra ethanol produced would be a net positive.
Recommend you look up "Pannage" much easier method used for 1000 yrs and still practiced to this day in the new forest. Get your food to eat the food. 🙂
Also remember Ray Mears video of grinding, wraping and leave them hanging in a stream for 3 days to make a tasty woodland food.
You crack me up.I thought that the alcohol that you used was inedible!We have black oaks where we live,and they are such a bugger to process! They have huge acorns! I hate it when I have to fish them out of my garden,and just throw them out.I live in a forest,so we just toss them to the forest critters,but I not that they only eat a bit of them,and that after rains and time have mellowed them.Using vodka is a neat trick,but my husband would tease me endlessly if I used that!(I am not a drinker)
If you want something close to free to ferment one coild use rose hibs. The kind that grows in sand or poor soil is the best. Also a great food source but tedious to clean out the seeds. You can make wonderfull marmelade from them.
John Kallas, of Wild Food Adventures here in the Pacific Northwest of America, has shown that leaching of tannins can be achieved in a few hours of an afternoon. High pressure spray from a hose into a flat pan with a supported filter, allowed to drain several times will do the trick. With this cold water treatment many of the fats and oils are preserved. This is a much faster and efficient mode of tannin removal than one hears of elsewhere, as I've seen for myself when I attended his acorn processing workshop back in fall 2010.
I've found it very helpful to use a hand-cranked nut cracking machine called the DaveBilt nutcracker. If the nuts are first dried and sent through the mill, mostly wholes and halves can be obtained to the tune of 40-50 lbs an hour (depending on your stamina!). Both are very effective methods that greatly reduce production time and the overall usability of native nuts and their oils.
Fascinating. Thank you!
Awesome video!..
..I could see this as a commercial process...divert some of the ending ethanol back to be used during the solute process...with side products to help offset overhead...tannins, flours, sugars, booze, ...what more does one need?
Seems a very straightforward simple process with scalability...Tremendous!!
IRC the leavings can be fed to pigs bacon bacon!
yeah it seems ideal to me too and there is also a win on the planting of oak trees !
@@ThinkingandTinkering I've got both hogs and oaks red and white and black as well as chinkapins...though it's a small acreage woodlot...it might be safer than moonshine lol
Brilliant yet again. Thank You
cheers mate
These are the types of video I like.
Thank you for sharing
If that really works, then I would love to see how you build a homemade soxhlet extractor, not the commercial lab stuff that fit only a couple of grams I want a one that fit kilos please. It hasn't to be all see through Glas though. A little window is enough.
Absolutely fascinating!!!! Thanks
cheers mate
Great video we have just learnt that acorns can be edible, so thanks for this video.
Just a bit of information. My ancestors here in America, turtle Island, were master's of permaculture. There being so many varieties of acorns each type was planted for there best usage. The lower tannin ones were eaten by people. Others were used for animal feed, I would expect that some were used to help in decorative painting or tanning hides.
The same selective plantings we're done for other nuts and berries as well as yampus, cat tails, and a variety of other food. This is why territory, was so important. And why the colonists we're so destructive to the first people and there scattered population. A single wagon train could stripp an area of game and other food products. Burn and clear farming literally stolen the food out of the local tribes mouths.
crimes against humanity, aside from the suffering and loss of life, the greatest loss is that vast knowledge base for all of humanity, its good you can help restore some of this knowledge now more than ever.
Excellent video
Brilliant, fascinating!
Sir you sound like Alain Villiers, a sailor from many years ago. Awesome channel
Wow awesome info, thanks
Brilliant video thank you 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
I appreciated the mineral and nutrient content coment near the start of the vid.. Im curious to these contents after these tanning leaching processes. If I know what's going in I know how to supplement.
We just never know what you will do next….which is why I follow you.
lol - well the world is a vast and interesting place mate
You can easily throw the dried meat into an expeller for it's oil. I've done this with good results. The oil tasted of minimal tannins, perhaps because tannic acid is water soluable? At any rate, the pressed oil may be the easiest food one can get from acorns - though a little more research is needed.
It is probably very easy and little time to extract the tannins from the oil with this method.
nice tip mate thanks for sharing
Amazingly good.
I was gonna say don't use methyl alcohol in any food product, even the trace amounts after drying is bad.
Vodka for sure, then distill it when finished for reuse. And then you have food, something that is apparently produced in megatons and mostly thrown away or left to rot or feed other animals.
I will definitely put this one on my survival skills list!
Well worth the watch Robert and as usual very entertaining. My Grandparents parents did this very similar thing and sold it as the poor mans flour. To what I was told as a young boy is that all the product would be placed in a Still and boiled at very low temps to collect the Alcohol, or was left to settle and then drained so the flour could be collected without destroying it's Bread making quality's.
This process leaves room for experimentation. How about washing the crushed acorns with the solution a couple of times. Do it for an hour and filter out the tannin solution and use fresh solution. Do it for another hour, and see if you remove more than 80 per cent of the tannin. I can think of even more ways of changing the process to see if that one is the best way of extracting the tannin.
For all I know, the researchers already have tried those methods, but without that paper being on this side of the paywall, I won't be seeing what they did.
Using soxhlet extractor with ethanol would wash the acorns with fresh ethanol many times over 3 hours. Probably remove virtually all the tannins.
@@kreynolds1123 I love that method, makes a great hot sauce too.
yes it does and I like that - I think folks should be experimenting for themselves
VERY INTERESTING...THANK YOU....from .Ro !
Great Episode. Surprised you didn't mention our Druid ancestors and their love of oaks.
I have fond memories of being taught the native American method of leaching with water. It tastes really good.
cheers mate
just the best videos..you missed a part of the circle, you use the waste of biofuel as humas for soil conditioner
amazing information!
Also low-temperature vacuum-distillation used in a 'free' energy process can recover the alcohol.
for sure mate - nice one!
Wow! This is nuts! 😁 👍
lol - isn't it just!
Apart from Ersatz coffee Acorns were fermented to Acetone by the Germans.
Britain fermented Horse Chestnut.
They got school children to collect these.
I'm not sure what microorganisms were used for this.
Acetone stabilises Nitro Glycerine & Cordite.
nice one mate thanks for posting
For someone who has a tree farm, if you are getting lumber and using the waste woody parts as either methanol or carbon liquor (lignin carbon fiber potentially) you could also use the nuts as a biofuel or feedstock as well🧠👍
Cool! Didn't know you are also doing experiments about nutrition.
If you own a garden, why not making a video on terra preta (a very potent soil for homesteading) and -even cooler- how effektive microorganisms (used to ferment the compost before turning it into terra preta) can be collected and multiplied insted of buying it.
Thanks for posting this.
Great great video 👍
You're a genius
Now you really made me chuckle once and a while. I hope they tasted well. What’s the rate of producing ethanol versus using it?
cheers mate - I don't really know I focussed on the process - but the paper was proposing it as a viable option
Another Quality video !
I'm glad to see you've taken a liking to acorns. I also see some of my photos utilized in your video, including the thumbnail image. Photo credits??
