Casein in Wine Causing Your Hangover?

Something that I have noticed since I started drinking mostly vegan wines is that when I drink vegan, I do not get hungover. This seems to be the case even with bolder, histamine heavy red wines, which for a while seemed completely out of the question.

But even with my handy list of vegan wines, there are times when ordering a vegan wine is not an option. So I do go ahead and drink it, but in most of these cases, the next day I seem to pay the price.

I'm not quite sure if there's much of an explanation for this, perhaps vegan wines are just less "polluted." Either way, I'm very glad that Ingles sells those eco-friendly boxes of Fish Eye's Pinot Grigio for just $17!
