Distillerie Berta is a great place to visit. They're in Piemonte wine country, near Mombaruzzo.
Berta has pioneered fine wines and Grappas. A great many of their grappas are barrel aged, as you see here in the refining shop--that's unusual for grappa.
But what's interesting is the tour. Grappa, being produced differently than wine, requires a different process.
