Netherlands-based Uxus Design created the tasting rooms at the Merus Winery in Napa, which feature Tom Dixon lighting and a chalkboard-painted strip for indicating wine varieties. Would love one of these in my house!
The eco-conscious LEED-gold-certified Cade Winery in Napa was designed by architect Carlos Fernandez of Lail Design Group. I like the vaulted ceiling and variable lighting. May be an option for the barrel wine tasting area.
