Not that I read the PETA stuff every day, but I could not resist when I stumbled on PETA’s article entitled, “Is Wine Vegan?” It makes the point that:
The majority of people are unaware that wine, although made from grapes, may have been made using animal-derived products. During the winemaking process, the liquid is filtered through substances called “fining agents.” This process is used to remove protein, yeast, cloudiness, “off” flavors and colorings, and other organic particles. Popular animal-derived fining agents used in the production of wine include blood and bone marrow, casein (milk protein), chitin (fiber from crustacean shells), egg albumen (derived from egg whites), fish oil, gelatin (protein from boiling animal parts), and isinglass (gelatin from fish bladder membranes). Thankfully, there are several common fining agents that are animal-friendly and used to make vegan wine. Carbon, bentonite clay, limestone, kaolin clay, plant casein, silica gel, and vegetable plaques are all suitable alternatives.
For those who would prefer not to torment an animal in the course of pouring a glass of wine, The Vegan Wine Guide already lists more than 400 wines. The Vegan Vine seems like a good example. As I flipped through a few of the 400, I was not surprised to see that few if any make direct claims that the wine qualifies as “vegan.” After all, TTB is not known for being footloose and fancy-free about various claims. Foursight Wines has said:
[we were] pleased that the TTB allowed us to state that our wines are suitable for vegetarian and vegan diets. Clos La Chance has begun marketing all vegan wines, but the TTB didn’t allow them to say that the wines didn’t use animal products (see the Wines & Vines article here). Frey is a noted vegan producer but their wines don’t list it on the label. So, unless anyone out there has a correction for me, I have yet to find another U.S. producer with a vegan and vegetarian statement on their wine labels.
If your tastes run in the other direction, you may prefer these libations replete with animal byproducts.
The guide you mention only listed Non US wines. Curious still as I had all my labels approved through you. Look at @herbivore on twitter for a good collection of vegan wines
