‘Somm 3’ hits the screen

The 2012 film, “Somm,” followed four Master Sommelier hopefuls as they tirelessly prepared for the notoriously rigorous exam. Its 2015 sequel centered on everything that goes into making wine, from weather to war to scores. ‘Somm 3’ will shift the focus to the people who most significantly shaped the wine industry, and a certain Central Coast wine plays an outsized role.
