Permanently closed
By A Yahoo! Contributor, 7/25/10
This winery has, as of mid-July 2010, closed permanently. Graeser Winery was located in the Diamond Mountain District AVA, in the hills above Calistoga. They had roughly ten acres of vines under cultivation, and produced estate Cabernet Sauvignon, Cabernet Franc, Merlot and a Bordeaux blend.
There is still some uncertainty as to what the property will eventually be used for, though I would suspect it to enjoy some sort of reincarnation as a winery/vineyard location in the future. The potential of the Diamond Mountain fruit is certainly great. However, for the time being, focus your time on other, more open locations in the AVA.
