The folks at Riedel Crystal rarely call wine glasses “glasses”: They prefer “finely tuned drinking instruments.” This is serious stuff. Now the Austrian purveyor of perfect vessels turns its sights east to sake, the high-octane rice wine of Japan. After studying shape, diameter, even thickness, Riedel landed on this, the “O” Saké Taster Glass. And it only took 25 tries, using a selection panel of sake makers and professionals from all over the Land of the Rising Sun. Yep, serious stuff. $12.90. and select retail stores.
