Did you hear Magnesium and Oxygen hooked up on the weekend? I was like OMg So good to see you guys back, Love the video! I'd love to see some details on heat ranges resulting in what sugars, pressure fermenting and just more beers haha.
Hahaha love the dad joke! Cheers man yeah it has been a bit stop start getting back into regular filming after the new years period but we are getting back into the swing of things now. True a vid around temps and how that’s affected by pressure fermenting, what yeasts are good for it etc is def something we can do
Cheers dude! We also have a cheat sheet up on our website here if it helps www.theflyingwombat.com.au/blog-posts/guide-to-water-chemistry-brewing-salts
When using a salts calculator (brewersfriend) I struggle to figure out how much of which salts to add. I add one item which then hits some of the mineral targets, but then when adding the rest everything gets out of whack, continuing adding various salts and soon nothing matches my targets anymore. It's so frustrating, which ones do I add first/last. Is there a better approach then just randomly trying to increase or decrease the various salts and hoping to get close to my targets?
Hmmm that sounds really annoying. Honestly I haven’t used brewers friend for this myself, but I know when you use Brewfather you can set your target profile and get it to auto adjust, then tweak the amounts from there. Adding different salts will adjust all the levels because these compounds contain multiple ions, for example calcium sulphate (gypsum) contains both calcium and sulphate so will adjust both, then slaked lime also contains multiple so on an so forth… so adjusting profiles does require a bit of playing around with it, but maybe I’d suggest giving Brewfather a crack? It’s been pretty great for me
It’s basically how many grams per 1000ml of liquid, so 1 gram of a compound in 1000ml would be 1000 ppm. So when we are talking about ppm in water chemistry it’s essentially how many grams worth of any given salt are in the total volume of the water. So if you are talking about 100L of strike water, 1 ppm would be 10 grams of salt
Having used pH meters throughout my career, I doubt that the cheap ones aimed at home brewers are at all accurate. I also doubt that they have even limited accuracy for longer than a year. The pH of tap water is very easily changed by additions (such as malt), so you probably don't need to worry too much about it. The exception is water with high hydrogencarbonate (bicarbonate) concentrations, which will lead to higher pHs, and will act as a pH buffer. Rather than worrying about measuring pH, I just add sufficient acid (sulfuric, hydrochloric, lactic) to react with the HCO3- and bring it to the desired level. I start with a reported 266mg/ml and bring it down to 40mg/ml for light beers. This will raise the sulfate/chloride/lactate concentrations, depending on which acid you use.
Yeah unfortunately at the home brewer level we make do with what tools we have! But very good advice though mate, certainly something worth remembering for future brews

@@flyingwombattv awesome sauce, I'd love something looking at overnight mashing too!
actually that is the plan for one of our next brewdays, small spoilers but we wont say what exactly what it will be
@@flyingwombattv awesome sauce! Absolutely looking forward to it!
Hi - ex chemistry teacher here. That joke doesn't work for me because you get MgO. Correct ratio, though.
Your videos really help me out a lot. thanks for taking the time to post good content.
Cheers dude glad it helped!
Nice work, gonna have to watch it again and take some notes

Very good/interesting video mate. Cheers 🤙🍻
Cheers mate!
You should mention that many tap waters have chlorine/chloramine which should be avoided for brewing.
Very true good point. This is why you should get your water tested and/or a report from local council

Can you please explain the PPM? For example, how many grams of sodium is equal to "x" ppm?
