I saw these on the shelf of my grocery store http://adultbeverage.co/, so I emailed. I mentioned the peanut allergy and asked about tree nuts, excluding coconut. Here's the (very quick) response I received:
I am happy to report that our products are peanut free and made in a nut free facility! Enjoy...
At time I'm posting this, they're only making Adult Strawberry Milk, Adult Chocolate Milk, and Adult Limeade. If they come up with any other flavors, we'll have to check again that this still applies. I know they don't sound all that great at first, but since Kahlua and Bailey's are out, depending on how these taste they might make ok mixers...
