Vineyarddesignate wines?

These are effectively the US equivalent of ‘lieu- dit’ in French – a wine for which the vineyard that the grapes come from is specified on the label. The usage is quite widespread in the US, and Heitz was the first in Napa Valley to adopt the practice of naming its vineyard sources – preceded in all of California only by Ridge with its Monte Bello Cabernet, just a few years before the first vintage of Martha’s Vineyard.
