I got a cheap air popcorn popper for Christmas and a bag of raw coffee beans and that’s all I use… for the extract, all you need is a mason jar, some grade B vanilla beans from Amazon and some 80-90 proof vodka… chop up the beans, throw them in the jar and fill it to about half inch from the top with vodka… then we let it sit for 4-6 months shaking it once and a while until we strain the liquid and bottle it.
