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.

    There are so many brilliant opportunities to direct your hate to, and you waste it on people who got more lucky than you in consumerism? Amateurs. *laughs an evil black metal laugh*

    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.
