I may have missed it, but I haven’t seen anyone mention Grassl. I have a fair amount of both Zalto and Grassl glasses, and find myself gravitating towards the latter. I haven’t done a taste test side by side (which I should do), but I like the shape of the Bordeaux glass a great deal. Truthfully, I can use either and be perfectly happy.
I have one Zalto universal remaining and a bunch of Glasvin universals…for a while I tended to reach for the Zalto, now I’m indifferent. Both are fantastic.
I had a few Zalto universals but they were broken by a friend and we were unable to source replacements. He purchased me a set of Jancis Robinson x Richard Brendon glasses which i’ve really enjoyed.
