Mental Floss already destroyed everything you thought you knew about booze earlier this year, and now the Internet is busting another booze-related myth: frosted beer mugs can actually be terrible for your brew.
The Kitchn spoke to a certified cicerone (aka beer sommelier) about chilling beer glasses, and it turns out they can seriously damage the flavor of your suds. Most of the time you're pouring an already-cold beer into a frosty mug -- and since the ideal serving temperature is between 40 and 55°F, the brew drops far below that range. Those lower temps mask the flavor of beer, meaning you accidentally just ruined the $2,000 barleywine you've been saving. The good news? Frosted glasses are still viable for room-temp beers, so if you've got some six-packs in your garage, go nuts. But when it comes to the stuff living above your crisper, stick with your prized Donny Osmond cup.
