They are getting 5 stars for the passion that they are putting in to this place. It's a brand-spankin-new distillery, and they are the first distillery to open in Pittsburgh, as Nick says, in 90+ years. PA is slowly moving away from their Blue Law past and allowing the alcohol-producing companies put down new roots. Amen to that!
The distillery is a very small operation; in our tour they mentioned that most companies "small batch" varieties produce more in one "small batch" than Wigle does in an entire year! Their still is bad ass, and is a modern copper kettle variety, imported from Germany. It's worth looking at.
They are currently only have two products for sale right now, white Rye whiskey and white Wheat whiskey. I picked up a bottle of wheat, as it has some unique flavor, and I believe it will mix well in many traditionally-vodka applications. The rye, while it has great flavor very reminiscent of how a grain bin on the farm smells (yeah, I grew up rural, so?) I just don't like it enough to drink straight, and I don't know that I could mix much with it, either. They are however aging it and it'll be ready to go in a few years...at which point I shall return.
I love the spirit that these folks have, and the fact that they are just figuring it out as they go. I am sure they will continue to refine their products and create new ones, and you should stop in to support that effort. The bottles are ~$32 each, so it's not going to break the bank.
