Company email (October 2019)
"The reason why our wines are not considered vegan is due to the fining agents we use that are animal based."
Company email (circa 2009)
"They filter mostly with clay, but use egg to soften the tannins (50 parts per million)"
Company email (circa 2006)
Fining agents are used on a lot-by-lot basis by the winemaker to optimize wine quality. Some fining agents contain proteinaceous materials. Proteinaceous fining agents are used to react with color and/or tannin molecules to make them removable by subsequent filtration. Both the fining agent, the color and/or tannin it reacts with are removed by the filtration process.
All of our fining agents are approved by the Alcohol & Tobacco Tax & Trade Bureau (TTB, formerly the Bureau of Alcohol, Tobacco and Firearms)
One of our standard fining agents contains Micronized potassium casseinate [casein is milk protein], food grade gelatin, egg albumin and other food grade components.
