I bought pretty cheap glasses a year ago where the rinsing water beads up into pretty large drops. The wine clearly tasted worse from those glasses Conversely on my Zareltos , the rinsed water comes off in sheets, not leaving drops, indicating lower surface tension. There is some water beading in my daily drinker Costco glasses… Wonder if this is having any detrimental effect on the taste
Has anyone noticed a relation between water beading and wine taste?
This could be a MW paper on the correlation of wine glass shape, cleaner composition, water chemistry and fabric softener residue on buffing cloths related to how quickly fruit flies sink into wines of differing ages, alcohol levels and latitude of harvest.
Surface tension is a property of the liquid in question (wine), NOT the surface the liquid is interacting with (glass). Therefore, beading vs sheeting of wine in different glasses is not due to surface tension. Instead, you are referring to a property called “wetting”. Because wetting is an interaction solely at the interface of the wine and glass, I doubt it would have much affect on the way wine is perceived. There might be small differences in the release of from compounds from a bead vs sheet of wine, but I imagine that these small differences would be overshadowed with a few swirls of the glass.
I would thing that the differences you are noticing between cheap and nice stemware is due to shape and thickness, rather than the wettability of the respective glass surfaces. But that’s just a hunch. The only true way to test the affect of wetting would of course be to have two glasses of identical deminesions that vary only in terms of wettabilty and compare side by side.
