I don't particularly care for extracts, but I have made vodka infusions with nuts. I used 5 ounces of roasted, peeled, crushed hazelnuts in 6 ounces of vodka. Let sit for a week or so, then taste it. It should be pretty nutty. When ready to bottle/keg, I took several 1 oz samples, and added infusion to them. 1 drop, 2, 4, 8. When I found the amount I liked, I calculated how much for the whole batch. I've doe that with several flavors, and it works fairly well.
