There is a local brewery next to my work, and they make and sell peanut butter porter beer - it sounds disgusting.
For peanut and treenut free alcohol, I work in a restaurant with a bar, so I've called on a couple things.
Decoy Wines (So I've been told)
Angry Orchard hard Cider (they just use apples from different locations)
All of Mike's Hard
White Claw
Again, you may need to check again but these are the ones I've attempted to contact..
