After almost a year of research, development and testing, the team at Aged & Ore has finally released all the details on what might be the best whiskey glass out there. The Duo glass is a hand-blown, insulated, double-walled, borosilicate glass that’s purpose built to be the only cocktail / spirits / whiskey glass you need. First off, it’s specially designed to perfectly accommodate a 2″ ice ball (your purchase also includes molds) at the bottom, so no more unnecessary jostling of your favorite ice as it chills your drinks. The insulated construction also means ice will melt slower, you can use it for hot toddies, and you don’t need to use a coaster. Speaking of things you don’t need, the duo glass has 1 ounce pour indicators molded into the inner glass, so you don’t need separate measuring tools. As if all that wasn’t reason enough to get excited, the chamfered square base transitions into a circular top profile which makes it ideal for drinking as well as holding.
