Happy New Year! Wait... what is that thing? It's a refractometer, which measures the sugar content in grape juice. For champagne grapes, winemakers look for a reading of 19. (Table wines should be 21-24.) This one was used at Stag's Leap Wine Cellars, in Napa Valley, California, for the 1997 harvest. #cheers #champagne #brix
