The Chappellet Winery sits on picturesque Pritchard Hill, near St. Helena, in California’s famed Napa Valley. Its owners wanted to expand its storage capacity and commissioned construction of
a structure called a barrel chai, a wine aging room that requires a very controlled interior environment. The planned structure would house 4,000 barrels of wine, a wine-barrel wash area and a small white wine production space.
To protect the quality of the wine, a barrel chai must be stored in low to no light conditions because sunlight can damage wine. Temperature stability is also a must to preserve the quality of the wine. Finally, because of the winery’s scenic location, the owners did not want a dull, boxy storage building.
