Just when you thought it was safe to come out of the root cellar, along comes Grainstorm, a big, wet wallop to the senses. Dark clouds gather on the horizon of your glass. A high-pressure system of pungent hops collides with a stationary front of barley, oats, wheat, and rye. The forecast: a monsoon of flavor with surges of roasty malt, microbursts of fruity notes, and a chance of golfball-sized hail. The extended outlook calls for unseasonably pleasant enjoyment.
