Brewing requires cheap ingredients but has overhead at ~4x the ingredients.
For a brew I’m thinking of, before the equipment, there’s four different malts, three different hops, yeast, and dextrose (<$50). Malt must be milled before steeping it like tea for the wort that will eventually ferment into beer, and this requires I have a mill or access to someone who has a mill (hopefully $0). If I don’t buy it pre-milled, I need to hope that Bell’s Brewery or One Well can help me figure out how to mill it. With the ingredients considered, I need the equipment to work the ingredients. I need large containers, bottles, a big pot, a bottle wand, plastic tubes, and sanitizer (i.e. Star San) (~$150). $200 total for a first-time brew and $50 per subsequent brew :)
