Company email (March 2018)
"Although the wines do not use animal by-products in the wine production process at all, they do use a fish oil by product to spray in the vineyard."
Company email (December 2012):
"I hate to say it but, yes we do use Icing Glass (a by-product of fish) in the filtration process of our White Wines.. mind you, our Red's don't require that level of clarity.. so you're safe there :)"
