About 5 years back I had the opportunity to buy a bunch of different Zalto glasses at the distributors cost as a thank you for helping them out. I grabbed a dozen assorted stems (Bordeaux, Burg, and the Universal) for roughly $25 a pop. Absolutely stunning. Here's a little secret, the universal stem from Spiegelau Defintion series is a damn good fill in if you don't want to drop the coin on a Zalto. Like a 1/3 of the cost. Not a big fan of the other Spiegelau Defintions but the universal is a home run.
