With worldwide album sales surpassing 30 million copies, four Grammy nominations and consistently sold-out shows on some of the world’s biggest stages, Josh Groban has been a star vocalist since his teens. Now, he’s making a “Find Your Light” Sonoma Pinot Noir with Ross Halleck. Groban spoke to Wine Spectator’s Lexi Williams about learning the tricks of blending after a few vintages’ experience, how he caught the wine bug, and what wine and food sacrifices he has to make on tour.
