There was I thinking alcoholic grape juice was a Vegan as you can get. Turns out they use animal derived products as fining agents which basically remove any left over particles and leave a clearer looking wine.
Now M&S and Spar, two UK supermarkets have announced that their own brand wines will in future all be 100% vegan using only vegetal sourced fining agents.
I wonder if that has any effect on the taste or appearance of the wine.
