Nice one pal. Just bought one after your messaged me. Can’t wait. Thank mate.😎👍🍺🍺bri n Kris
I'm just about to buy two more all-rounders!
Let me know how you get on. I wouldn't open transfer again.
@@MadeByMartyn will do mate. Just to think nearly 40 odds years brewing and bout time open transfer is a distant memory lol. Think I another one will bought soon I bet!!! Haha! Cheer pal Bri
This is the process I've been looking for! I love very hoppy but otherwise light beers. Doesn't break the bank either! Thanks for sharing
Great idea with the starsan keg and distilled water.
I'm still using that closed transfer :-)
Unless you completely filled the second all rounder with Star San, it still had oxygen in it.
Granted, in theory, the co2 should be at the bottom protecting the beer and the oxygen should be at the top being pushed out of the spunding valve.
Both were fully purged with CO2
Enjoyed that 👍 and I’m off to buy a 2nd all rounder. My last NEIPA got seriously oxygenateded but this gives me the confidence to try again. Will you transfer again to a serving keg or or put the AR straight into the keezer? 🍻
I'll leave the hops for three days then cold crash it in the fridge down to 1°c for about 3 days before doing exactly the same closed transfer into a corny keg.
I'm really liking the All Rounder and have two more brews lined up so need to get this one empty ASAP!
Thanks for that. I've been wanting to set up a closed transfer system myself by modding an old King Keg plastic barrel I have lying around. I think I might invest in a couple of these Fermzillas instead. How easy are they to get your arm in to clean them or do you just let the chemical cleaners to do the job?
That beer looks lovely. Unfortunately my brewing gear is packed away pending a house move. Can't wait to get brewing again.
Cheers
Cleaning is easy as the top hole is huge compared to some fermenters. I've the original Fermzilla too and the "All Rounder" is far nicer to work with.
Hope the move goes well,
Stay safe.
Cool video. How do you filter beer from the hops afterwards?
If using leaf hops a simple filter, however I use pellets these days so cold crash down to 0.5°c for a couple of days before kegging.
Hi Martyn
I am thinking of getting a couple of all rounders having watched your video’s and as I currently only bottle beers and want to try a couple of NEIPA’S
I notice that there is no air lock on the fermenter and you are using a spunding valve my question is did you ferment this brew under pressure? If not what pressure was the valve set at ?
Great channel keep them coming
Mitch 👍🏼
I pressure ferment at between 5 and 15 psi set by the spunding valve.
If you're bottling you can still do a complete oxygen free transfer using the Boel iTap.
@@MadeByMartyn Many thanks 👍🏼👍🏼
Hi, this is a really useful video. Can I ask what pressure you set you spunding valve to? And are you hoping to achieve carbonation in the fermenter?
On this brew I didn't carbonate in the fermenter,however it would have been easily possible, effectively turning the fermzilla into a unitank.
I fermented this and dry hopped it at about 7psi (guages aren't very exact in that sense).
Great video Martyn. This is a great idea, how did the finished beer turn out?
I think a number of factors colluded to make this quite possibly one of the best brews I've done using the Fermzillas. I also used the WHC Sanders Vermont yeast (hence the name of the beer) which is remarkable. The closed transfer is something I always do do now for stuff like NEIPAs meaning there's no oxygen from pitching to pouring and I'm convinced it's a major contributory factor.
Hi. How do you get clean beer from that much of hop pellets that dissolved into beer in dry hopping? Wouldn't hop sock is better option when dry hopping? Thanks.
The pellets don't dissolve as such, more break up into very fine particulates. These are then dropped to the bottom of the fermenter by cold crashing at 1°c for 36 hours.
Whether your a Muppet or not I watched the whole thing. Cheers
Hi Martin. My idea is to add the hops through the top into a primary fermentation (about to an end). Yes, I will get some oxygen in, but this should be blown away by the CO2 from still fermenting beer
What do you think? Also, how effective is the cold crash in the all-rounder? I have just ordered one and can't wait to try it myself
To be honest, "chucking the hops in the top" was my mode of dry hopping right up until getting the all rounders!
More recently the closed transfer has been an experiment, mainly with NEIPAs - to see how different the finished beer tastes having been dry hopped off the yeast cake / trub.
@@MadeByMartyn And? Was it worth it? I mean additional transfer = more washing which we all love
I think for really heavily hopped NEIPAs where I'll chuck 250g to 300g in for a couple of days max it freshens the hop profile but again, I'd have to do two side by side and offer blind tastings (which I'm sure all my friends would like to help) in order to be sure :-)
Did you leave co2 on while opening lid to drop hops? I assume some oxygen had to get in when opening secondary…. Have you thought about putting food grade magnets and fill open sock with three magnets take one or two off to allow sock to dump hops into closed secondary?
I didn't remove the cap, the hops were in a clean, sanitised fully purged fermenter. All the oxygen had been removed during that purge. Therefore when transferring from one to the other, it was completely oxygen free.
@@MadeByMartyn I will need to watch again. I saw you pump Star San in empty secondary and back out. Then video showed dry hop pellets in the bottom. Where the hops added then you put Star San on top of them??
@EricJD1966 after cleaning with Star San, transfer it back to the corny keg. Then open the top and drop the hops in, put lid back on, purge again (doesn't need much) then transfer the beer. An easy way to check anything is fully CO2 purged is to carefully sniff the PRV as you're purging - if you get a fizzy sensation you're sniffing CO2 and it's fully purged.
@@MadeByMartyn I am fairly new brewer. Two all grain brews under my belt after a few extracts. Have fermented a stout and transfer into serving corny for first keg beer. Just fermented a Kolsch in five gallon corny with a Flotit 2.0. Went to pressure transfer to second keg only to find out the float dip tube came off post… so had to use racking cane. Next wanting to do a heavy dry hopped NEIPA and probably worried too much about oxidation. And purging secondary corny with Star San and CO2 and opening lid quickly and dump pellets and seal up back up should be fine. I tend to not always Relax Don’t Worry and Have a Homebrew!!!! I pushed the limit of Kolsch in corny and had some yeast blow out the blow off so maybe that was enough to get enough movement to detach float tube???? Negative of stainless steel fermenting is one can’t see what’s going on with the fermentation process.
@EricJD1966 dip tubes do occasionally pop off - I've had it happen once. I think we can sometimes get a little too obsessed with oxygenation - at homebrew level it's important to be conscious of it, but equally as important not to let it cause undue worry.
I close transfer all NEIPAs and Pales out of habit now.
Enjoy :-)
6:00 if you open the outer ring a bit and put a key under your red caps it will pop right off and you will safe your co2
I was a little sceptical of this solution, until I tried it, gently, with a bar blade, and it works.
Cheers!
:-)
Cant you just link the jumper on both gas posts then decrease the pressure on the empty vessel and use the 1st vessels gas . Also couldnt you like the vessels at the start of fermentation and purge the vessel with free co2 made by fermentation
There isn't enough existing CO2 to facilitate a transfer (tried that). Harvesting the CO2 during the fermentation would be possible but would involve having two Fermzillas tied up at one (and a larger fridge!). I'm no sure how much carbon dioxide is created during a fermentation.
I think it might need to be a little bit shorter
Nice video, excellent tutorial.... So.... what's with your plastic girlfriend in the background at approximately 8:25? lol... No judgement, of course!
She's one of three. This one is Delilah - very long story which may make it to a video in its own right one day!
