There’s a channel called “Tech Ingredients” that features a variety of interesting stuff.
This is slightly on the long side, but I watched it last night and found it oddly compelling: “Distilling ALCOHOL With Our New Reflux Still!”
I also generally don’t like videos that focus on a specific product, but in this case, the video is less about the specific reflux still and more about the general workings of one, including things like the design of the bubble plates and the dephlegmator.
Bonus video #1: Previously from “Tech Ingredients”, “Banana Brandy – Making Ugandan Waragi (Moonshine)”.
Bonus video #2: This also appeals to my geek instincts, but doesn’t involve booze: “Jet Engine Thrust Test – Fuel Experiment (Jet-A vs Diesel vs BioDiesel vs HydroDiesel)”. The guy built his own dynamometer, and then tested these fuels to see which one produces the most thrust.
I’m also a sucker for small jet engines.
