Pedroncelli Winery & Vineyards has some vegan options

Company email (April 2013): [regarding Dry Rose of Zinfindel]
"Our Rosé does not require any fining (such as egg whites or other animal products) and is filtered before bottling as a standard procedure and no animal products of any kind are introduced into our Rosé."

Company email (March 2013):
"Our Three Vineyards Cabernet Sauvignon and Merlot are fined using egg whites but our wines are filtered following the fining and before bottling and any animal products in the wine are removed at that time.
Egg whites are not used in our white wines so our Chardonnay does not have any animal products used in wine fining.

We do not use isinglass or gelatin in our winemaking process or any other animal products that you mentioned other than egg whites."
