Does anyone know where I can pick up small cubes of fresh yeast? Fleischmann's or Red Star are fine. Central Market (and some HEBs) usually carries the former, but they've been out for awhile and are apparently having supply issues. Whole Foods doesn't carry it. Same with Wheatsville. I've called a handful of local bakeries and health food stores without luck. Homebrew supply stores have primarily moved to dry yeast. Suggestions?
