Despite the fact that I don't drink alcohol, I've found the "How to Drink" channel on YouTube a really fascinating look into a world I know very little about. This is what I want potion-crafting in an RPG to feel like. Assorted weird ingredients with their own histories and quirks, each there for a purpose, and the need for some deep understanding of the process or else things might go badly wrong. Plus, of course, lots of great colors and textures and occasional flame.
