Interesting thanks.

For those curious as well:

Since some finings are animal products and others are not, it can be difficult for consumers to find out whether a particular wine or beer is vegan, vegetarian, or neither, unless the producer or seller chooses to label it as such.[6] The website Barnivore maintains an international database of wines and beers, classifying each as "Vegan Friendly" or "Not Vegan Friendly"
