Makita heat gun, large stainless bowl, colander, green beans. Beans good for a couple years, weigh them into colander, 70 grams after roasting, forget the green weight. Just as they turn dark brown and oily , and the first crack flak gone, dump in bowl to cool. It happens so fast, so is hard for me to not get dark roast which I like anyway.
Then french press, then into a thermos thing.
Haven't done it for awhile, and this thread reminded me I have a sack of green beans.
It seems the caffeine in this is much stronger. I usually only have a cup of drip for for a kick start, but this is engine nitrous boost.
