Hey, chemistry nerd here. Regarding extraction. Many people here talk about ethanol (vodka, everclear), but with that, you either need to evaporate it to concentrate it, which kills a lot of flavor, or you need a high ratio of beans to solvent. Another great option might be di**methyl**ether (DME). It is sometimes used for making cannabis concentrates for example, so you can get it specifically for extraction purposes on Amazon for example. It's delivered in pressured cans, you fill a metal pipe with your beans, and blast it through. It will be freezing cold (-30°C), and the solvent evaporates very quickly and without residues. It pulls out everything, but mostly flavor compounds and lipids. That way, you can get a highly concentrated extract without alcohol. Maybe that's a tip worth considering?
