I don’t use bash, bash uses me

Fair point. IIRC though the primary reason for banning plastic straws was not CO2 emissions but wildlife protection, as plastic straws are (or were) the single most frequently found foreign object in the stomachs of dead sea turtles.

I’ve got no data to prove or disprove this gut feeling of mine, but aren’t most separatist movements motivated like this?

Fractal shorelines. Always a pleasure to behold.

Now I think of the Roman Empire again, damm

The overall liquid amount is like 9 - 10 ml, of which ~1.5 ml is whisky. That’s still not little, but it’s more like 6 % abv, so far from the 15 you calculated. But I agree that even that is probably a tad much. On the other hand, if I want to use it in a co-fermentation or even staggered pitch, it has to be able to take a punch.

Thanks!

So long, I find that it's doable since it can be broken down into chunks and I can fit most of those into my everyday life a lot easier than, say, a full 5 - 8 hour brew day. :)

It should be palatable at least - and I don't want to die. I understand that the latter bar is the easier one to take, but not granted.

Sounds nice! Why not keep us in the loop and post updates here :)

Thanks for the hint! I don’t see myself having time for an entire book anytime soon, but I’ll certainly put it on my list.

The oak litter idea stems from more recent studies where IIRC they found that brettanomyce is rarely found on the skins of fruit, only in vineyards where they dump their pomace (?) below the actual tendrils, but in forest floors and most particularly in oak litter.
If you’re interested, I posted a link to a video by suigeneris brewing where Bryan explains just the above somewhere here in the thread.

 

Soaked some decomposing oak leaves for 36 hours in preboiled water with some yeast flakes. Stirred, put 1-2 ml into test tubes with 5 ml of malt beer ("Karamalz", I just picked a random brand), filled up with equal amounts of 5 % vinegar and whisky (didn’t have any vodka at hand). Put a thin layer of neutral vegetable oil on top.

Should keep out the vast majority of bad microbes and provide a mostly oxygen free environment for yeast.

IIRC, I’ve also read on suigeneris brewing that oak leaf litter has a 50 - 80 % chance of catching bretanomyce, which I’d be thrilled to find.

 

My test batch setup is nearly complete (please also appreciate the "beautiful" tiles) and I tested it with a wet hop beer. As you can see, those were clearly at the upper end of their ripeness scale, but it was the only time I could manage to pick some at all due family & kids.
In they went in for a ~20 minutes 80 ˚C hop stand, during which my kitchen smelled a troubling lot of garlic and onions. By removing the bag with the hops, I stirred up the already settled trub, so I had to pour all hop debris & hot break into the minikeg along with the wort. Let's see what that does to the beer. I've overshot my OG quite a bit with the setup in the pictures, with a lot higher efficiency than predicted, only by stirring every now and then, so we're looking at an OG of 1.051 instead of 1.046.

Yesterday, after a week of fermentation under rising pressure, it was time for a gravity sample. It's fully attenuated already, and except a hint of some sharpness, I'm happy to report that we're apparently free of off-flavours. :) It came down do 1.008 (vs 1.010 predicted) , which leaves me with a 5.6 % ABV beer instead of 4.2 % with a lot less residual sweetness (US-05, you monster). Next time, I'll certainly mash hotter, and check the temperature with an external thermometer as well. I also wonder what a Kveik yeast would do to the result.

Here is the base recipe I intend to use for ongoing experiments with malts, yeasts & hops.

 

Hi!

I noticed that I don't get anywhere close to the gravity Brewfather estimates for a given recipe. Latest example is a SMASH IPA with a good 5 kg of pilsner malt that, which on my BrewZilla Gen 4 should have landed me somewhere around 1.054 pre boil. Everything went according to the recipe: 71 °C strike water, 64 °C mash for one hour (even a tad longer than that due to being interrupted by having kids), nice recirculation all along, no visible dough nests. What I got though was a pre boil gravity of 1.037 (forgot to test for starch being still present with iodine though).

This is only my fourth brew on the system, the first I forgot to measure and two were rather experimental, but I am still noticing a pattern here in that my efficiency is rather consistently sub par. I now wonder where to find room for improvement. For me, there's no need to squeeze every last bit of sugar out of my grains, yet at a mash efficiency of only 54% where in theory I might even get 80% does not only strike me as unnecessary wasteful, this way I don't know if I could even make anything bigger than an IPA at all without stretching the limits of my system.

My grain milling is one of the things that I suspect might contribute. So much so that I already wish I hadn't bought a three roller mill but one that I can adjust with simple advice from the internet, it seems everything in this field is geared towards two roller mills.
Also I started thinking about pH. Until now I never tampered with it, does it really have the potential to make such a huge difference?

All other suggestions are welcome as well. Cheers!
