It only took one word to get me into Piccolo Forno's annexed bar, and that word is grappa.
For those who do not know this spirit, grappa is made by distilling the waste products from the wine-making process (think skins, pulp, seeds, etc). The result of the distillation process is an extremely concentrated, very flavorful, and incredibly high-proof alcohol that quickly became one of my favorites during our travels around Europe.
For reasons unknown to me, this spirit has not taken off as much in the USA, and grappa has been something I've only enjoyed while abroad- until now.
Congratulations Pittsburgh, you're now officially a European city.
