Double-Wall Insulation and No Sweat
Temperature retention is the most praised quality. The two glass walls trap a layer of air, which slows heat moving from the room and your hand into the beer, so it stays colder for longer than in a standard glass. One owner found the cold, crisp taste lasted long enough to drink slowly, and another explained it simply: the air space between the walls does the work. The other benefit is the one many owners notice first. Because the outer wall does not get cold, there is no condensation, so no dripping glass, no soggy napkin and no ring on the table. One owner who dislikes sweaty glasses calls this marvellous. Double walls do not make beer colder than it started, so chill the beer properly and, for the best result, chill the glass as well. The walls also make the glass comfortable to hold for a long drink.
