I like to think that beer is better in the right glass for the style. Has anyone got a good line on Belgian beer glasses? Most of the stuff online (Libby products) look more like tulip glasses rather than the chalice shape preferred by Orval, Chimay or Westmalle for their branded glassware.
I just did a glassware search myself (trying to find 0.3L/~12 oz. Willi Becher glasses), and searched a ton of places, including eBay, Etsy, Amazon, general Google searches, etc. It's really hard once you get out of the morphospace of "Shaker Pint" and "Tulip Glass," especially if you want glassware without branding, and even harder if you want glassware in the 12 oz. or smaller size range. I ended up finding what I needed on Amazon, and that was after a pretty exhaustive look elsewhere.
In the Before Times (prior to the pandemic), I sometimes had luck in local thrift stores and antique shops (where I got a really nice set of German pilsner glasses!)...but that's really hit-or-miss, and I always have the best finds when I'm not looking for anything in particular.
