That shape looks a lot like the Riedel Sommelier Hermitage glass, one of the more gorgeous Riedel wine stems (IMO). I own one (from a Riedel seminar at Hospice du Rhone) but rarely use it because it seems scary fragile.
These days I tend to use a Burg glass for Pinot, Nebbiolo, Grenache and the like, and Zalto Universal for Cab, Syrah, GSM, and other bigger reds.
I bought some more because I liked them. A couple of my second batch seem thinner. Not sure whether they have changed over time (and maybe changed back), or itās variability.
I broke two of the Riedel Somm Hermitage just looking at them ; ) I now just use Zalto (Universal or Bordeaux), Grassl (1855) or GGG for N. Rhone and Syrah.
I prefer Syrah out of my Gabriel Glas StandArts. Iāve tested multiple Syrahs from Cali and N. Rhone out of Zalto Bdx/Burg vs. the Gabriel Glas and every single bottle the Gabriel Glas has spanked the Zaltos in my opinion. This is the only varietal for which Iāve seen such one-sided results.
Historically, itās been the Riedel Ouverture red. For the past year Iāve primarily been using the Grassl 1855. And now Iām going to give the Glassvin Prestige a shot.
