    Is the beer gas ratio measured by volume or by mass?

    I'm looking to fill my 5-liter nitrogen cylinder with a blended gas consisting of 75% N2 and 25% CO2, and I have reasons to believe that my welder filled the cylinder with too much CO2 as my brews were getting overcarbonated whilst on beer gas. And I want to get it right this time around...

    Perfecting nitro pours - any tips?

    Hi all! I recently acquired some beer gas and a nitrogen regulator and decided to serve my Irish dry stout on nitro. I’ve pulled a few pints and the results are somewhat satisfactory, but we all know that this is not acceptable for us homebrewers :) I’m using a 70/30 N2+CO2 blend My serving...

    Nottingham underattenuation issues

    Have you guys experienced underattenuation problems with Lallemand Nottingham? My dry Irish stout has been fermenting for almost a week now and has been sitting at a stable 1.016 FG for 4 days. The yeast has completely crapped itself out and flocced in a tight cake at the bottom of my FermZilla...

    Hi all, According to Brewfather, I hit 90% mash efficiency at the end of my latest brew day. I exclusively do full volume/no sparge BIABs. To me, this number sounds abnormally high given the fact most people are pulling around 70-80% mash efficiency using full volume BIAB. The question is: how...

    Using chrome-plated brass disconnects in mash recirculation?

    I recently upgraded my kettle by building a Clawhammer-esque mash recirculation system with a spray nozzle. However, I just realized that the quick disconnects, that connect the spray nozzle and the pump's silicone hose, are made of chrome-plated brass. How risky is it to use these repeatedly...

    Diacetyl rest questions

    Brewed an American pale a week ago, pitched Verdant IPA and let it rip at 19c (66f). It reached terminal gravity on day 4. After that I dry-hopped using a bag and bumped the temp up to 22c (72f) to do a diacetyl rest. Just did a forced diacetyl test and the heated sample smelled a bit like a...
