Frey Vineyards is vegan friendly

Note: Frey uses biodynamic farming techniques.

Company email (April 2021)

"...yes, the Kwaya wine is vegan, as is all of Frey Organic Wines and Pacific Redwood Organic Wines"

Company email (July 2017)
"All of our wines are vegan wines, including our Pacific Redwood wines. No animal products are used during fermentation or during any other winemaking process."

Company email (September 2013):
[Do Frey wines contain any animal ingredients (such as milk, eggs, honey, etc) or are animal products used in the processing/filtration of the product (such as isinglass, gelatin, etc)?]
No, to all the above.

[Also, is your product manufactured anywhere else in the world (by a sub-licensee, for instance) that might use a different processing system?]
No.

From their website (http://www.freywine.com/organic-vegan-wine-sale.html) December 2011:

"Frey Organic Wines are Vegan Wines, as well as Gluten Free: No Animal or Gluten-Based Fining Agents are Used"
