That seems to be a pretty great idea for a mutual aid project: Make a community coffee dispensary whose mission is to brew the best coffee and give it to anyone who wants a cup. Large-scale production should be useful in controlling the factors of coffee production, hence only a short time of trial and error, the coffee dispensed should progress from bog-standard to half-way decent to pretty good to absolute best.

Stretch goals include a baked-goods dispensary that is attached.
