In today’s episode of the Happy Half Hour, hosts Erin Chambers Smith and Troy Johnson are talking the opening of a new Nomad Donuts, Point Loma’s newest beer tenant, and a wine tasting room now open in Little Italy. On our show is Karen Fortmann of White Labs, a local company that specializes in pure liquid yeast and fermentation products.
