Comment 3: Ovadya, Dan

I've spent some years exploring the Napa Valley and the south eastern end of the Valley is most certainly a unique area. In the late summer and on hot days, it's very apparent that the coastal climate affects this area longer and faster than other parts of the valley by reducing air temperature. Part of this is due to close proximity to the bay but this south east corner also receives more exposure from delta breezes. In comparison, south western areas of Napa are blocked off from delta breezes moving from west to east (seen on streakline wind sensors). This extended period of reduced temperature and increased air movement through the vine canopy and fruit clusters most definitely slows ripening. Exposure to coastal influence also narrows diurnal humidity ranges which greatly affects the crops water and carbon use efficiency. This creates a very unique opportunity for Bordeaux varietals in which ripening is slowed and the crop has an extended opportunity to create complex flavors, rather than more residual sugars. I personally choose to drink red wines from the region for the consistent quality and special flavor. I fully support making Coombsville a distinct AVA.
