I like the olde tyme medicine / cocktail bitters type taste!

I had a fun time last year outside of Pittsburgh there was a diner that had the original soda fountain in it, and I ended up talking with the soda jerk about a lot of the oddball ingredients and he gave me some of the phosphates and I was tasting them straight up and mixing them with flavors in different proportions and such.

A-Treat has an online store now, with the brown and white birch beers both available, as well as the pumpkin cream and cranberry ginger ale holiday flavors, which I also love. There's a few other Pennsylvania birch beers, the PA Dutch red version and the clear Kutztown ones are on Amazon I saw, but the A-Treat is the most local to where I live.
