Ninkasi Brewing’s latest beer: Ground Control. Last year, the brewery sent six vials of brewer’s yeast into space (77.3 miles up)—this was their second attempt to do so—and brought them back to brew up this Imperial Stout. Brewed with Oregon hazelnuts, star anise, cocoa nibs, and some astro-yeast, Ground Control is a full and flavorful stout. It will be available in select markets on April 13.

Koch told me that for years he has swallowed your standard Fleischmann's dry yeast before he drinks, stirring the white powdery substance in with some yogurt to make it more palatable.

"One teaspoon per beer, right before you start drinking."
