    Fermzilla - dry hop under pressure

    Afternoon everyone! I've been using my Fermzilla to ferment under pressure for about a year now and I'm very happy with it, but I still want to improve my technique when it comes to dry-hopping. Leaving discussions of hop-rockets, internal magnets etc aside for a moment, I wonder what you think...

    Adapting CO2 regulator to 70:30 Beer Gas bottle

    I've been using CO2 to carbonate and serve beer for just over a year and would like to try a 70:30 Nitrogen / CO2 mix, mainly because we can't get any CO2 right now where I live. I have however sourced a great big bottle of this Beer Gas, but it uses a different regulator connection. A quick...

    Second Batch of 2021

    Last week we picked our second apple harvest this year and pressed just shy of 75 litres, which I'm splitting three ways in the name of experimentation; two will be fermented with Mangrove Jack's M02 (one dry-pitched, one with a starter) and the remaining bucket will be fermented with a starter...

    Starter not ready - pause before pitching?

    It's brew day today, and the starter I've been building from harvested WLP518 hasn't taken off as expected after 18 hours on the stir plate and 6 stationary, all at 23℃. Normally I'd see a good Krausen by now, but this time there's almost nothing. Now I have several packets of dry yeast that I...

    Keg pressure leaking from PRV - replacement O-rings?

    Evening All, One of my Cornelius kegs isn't holding pressure, and on closer inspection of the PRV (constant hissing was a clue) it seems there's a tear in the tiny O-ring at the bottom of the PRV plunger. I've looked high and low, and while it's easy to find O-rings for disconnect posts, keg...

    Fun with Opshaug Kveik

    I've now got a couple of brews with the same Opshaug under my belt, each time top-cropping, saving, and growing the yeast before pitching it on brew day. It's been an interesting learning experience and actually way easier than I was anticipating - kudos to the kind folk on 'ere who answered my...

    Czech Pale Lager with 300 minute hop stand? Really?

    I'm looking to follow this Brewfather recipe for a Czech Pale and noticed it calls for a 300 minute hop stand at 98℃. That's five hours. At first I thought it might have been a typo but the notes section reads: "It was no chill , hence the 300min hopstand, though I do not like adding hops to...

    Kegerator build update: shelf fitted, beer taps inside

    I've wanted to build a kegerator ever since I started kegging beer; partly because it would free up my existing fridge solely for fermenting duties (was too small anyway) and partly because I was fed up with trudging to the brewery each time I wanted a pint. So when lockdown #3 ended for us a...

    Clean racking cane between batches?

    I'm bottling two batches later on today, an all-grain American Pale and a Woodforde's Wherry kit, wondering if I need to clean and sanitise my racking cane between batches or if I can be a lazy sod and just move it to the adjacent second vessel once I've finished with the first. If I simply err...

    First Time Kveik - any tips?

    As per title really. I'm having a go at Vienna Lager and intend to follow a Brewfather recipe by @David Heath, but I've never used Kveik before and need to know if there's any gotchas that are likely to trip me up. Should I make a starter (nutrients? pitch time?) or just rehydrate? On a related...

    Using recycled yeast with Brewfather - how to calculate pitch rate?

    Morning Gang! I've got what looks like 300 ml of yeast salvaged from my last brew, and want to try using this in a fresh brew, basically just to see if I can do it. Going forward I'm going to (over) build starters rather than pitching from sachets, but I'm waiting on equipment to arrive and...

    How long does Krausen stick around?

    I'm used to seeing our foamy friend reaching its peak during vigorous fermentation and then gradually disappear, but on my latest brew, a hoppy session IPA, it's still visible even though fermentation slowed down drastically 5 days ago: Normally I'd have expected Krausen gone around 8 Apr...

    Quickie: do I really need two packets of WLP001?

    I'm planning a session IPA based on a recipe in Brewfather for something called Twisty Listy. Among other ingredients the recipe calls for one packet of expensive liquid yeast from White Labs, WLP001. It's a 23 litre Grainfather batch recipe and uses a lot of generic malts which I don't have...

    Cold Crash in addition to Finings? Anybody?

    I'm a bit new to the world of cold-crashing at the end of primary since I've only recently acquired a fridge big enough, and I was very pleased with the results when I tried it for the first time. I'm also new to finings, and was equally pleased when a ⅓ Protafloc tablet cleared up another beer...

    Adapting recipes from Brewfather - am I doing this right?

    Morning Campers! I'm planning my next two all grain brews and have run into a bit of a snag, wondered if the Brewfather veterans among you could take a moment to point me in the right direction. My problem is that at the end of the adaptation process (below) I'm a couple of hundred millilitres...

    First AG brew, missed pre-boil gravity by 24 points

    This has been a ’learning curve’ kind of day! Mashing went well (far as I can tell) as did sparging, but I checked the numbers while heating to boil temperature and it looks like I’m 3.5 litres low at 28, and 24 points low at 1.020. OK, the wort was at 65C and not 20, but 24 points?! I had...

    Priming sugar after cold-crash: have I ruined it?

    I just finished cold-crashing a 9 litre experimental extract brew in a mini bucket for 8 days following successful fermentation. 5 litres were kegged and pressurised, the rest went into CO2 purged bottles with a couple of carbonation drops. Then it occurred to me: doesn't cold-crashing cause...

    Carbonation error while bottling Cider - OK to reopen bottles?

    I made a schoolboy error with my priming sugar quantities while bottling strawberry & pear cider yesterday, only added half as much as I intended because I counted litres and multiplied by bottles. D’oh! Am I right in thinking that I can just sanitise the flip-tops, pop ‘em open, and throw in an...

    Sparging with Brewtools B40Pro B80Pro B150Pro

    Following three months of deliberation I've finally taken the plunge and gotten myself set up with a Brewtools B40pro all-in-one system. It certainly feels like a fantastic setup but there's one question I keep coming back to as I mentally prepare for my first brew day: how do you accurately...

    DIY sparge water heater. How hard can it be?

    My AG setup is slowly nearing completion, and as my attention turns to sparging I'm wondering if the various dedicated products are really worth the premiums being charged when a cheap tea urn is really all that's needed. Except that cheap tea urns often come with a cheap tap and just an on /...
