Clos Du Val Wine Company has some vegan options

Company email (August 2011):
"All of our white wines are completely vegan friendly and contain no milk, egg, fish, or other animal based products of any kind. Our Pinot Noir is also free of animal products.
On occasion, our Cabernet Sauvignon and Merlot have small a small amount of egg white used as a fining agent. They however, contain no milk, fish, or other animal products.
Our products are only made at our winery in Napa and under our control at all times until bottling, so we can verify all products used in its making."
