I received two last year as a birthday present. Really like them a lot. Particularly for nebbiolo, but I have found them quit good for almost everything. I still use a Riedel Syrah glass for Rhones, and sometimes the Riedel Somm Burgundy for Pinot. I love the Grassls for whites, and occassionally use them for whites.
I have put the Conternos in the dishwasher with no problem.
I really like them, but not sure if they are worth the premium – which is what made them a great gift.
to me, the conterno glass is the one to rule them all. the weight and balance are perfect. no idea how, but the tulip shape really makes the nose jump. the one on the right in my photo which is possessed by the devil is a prototype (?) from Glasvin. a bit bigger than the conterno, but just as thin and balanced perfectly.
Hey David, as long as Glasvin is branching out, how 'bout a nice retro styled tulip like the one Jacques Seysses is brandishing in the pic from William Kelley’s 1980 burgundy article?
