I have the Oracle Touch, also bought it used, and it had probably been run in a cafe or so. Its cup counter was absurdly high.

Anyway: I second that you should look out for scale. I have hard water (~200 ppm bicarbonate) and never cared for the filters. It wasn’t too long before I noticed a constant hissing from the machine once it heated up, and it struggled reaching 93 °C. Turned out that scale had built up around the temperature probes so badly that it had damaged the o-rings. The escaping steam also had corroded nearby screws. I got it fixed and it still works, to this day, but I had to spend time and money I had rather used for something else.

Unless mosquitoes.

No, that’s a moray.

Not saying it isn’t, but it’d hardly be the first project I see where the git history was truncated before its release to the public.

My limit is not my hate, but time. Can't hate for more than 24 hours, no matter what. I hate that.

I’m laughing harder than is the poop of a fiber detestent.

Why does that skull have a double nose?

I don’t use bash, bash uses me

 

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.

 

I'm in the market for a reamping box, but after seeing Christian Kohle doing A/B tests, I only know two things:

  • the Palmer River Trave box brings in a strange hum (listen here with timestamp: https://youtu.be/lUHZs0z8wAQ?t=540 )
  • given how little I plan to actually do it, I'm not willing to spend < 300 € on something like the Radial

So are there some experts here, particularly for metal maybe? I'd be glad for some recommendations, particularly for stuff easily accessible in Europe/Germany.

 

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!
