Frosted mugs suit ice-cold lagers, but skip the frost for aromatic craft beer, where the extreme cold mutes the flavour and aroma." recommendation: name: "Wet a clean glass, freeze upright 30+ min for lagers — but serve craft beer in a cool, unfrosted glass" reason: "A frosted glass is simply a wet glass frozen until the surface moisture turns to frost, so the method is easy. Start with a genuinely clean, grease-free glass, because a 'beer-clean' glass holds a better head; rinse it inside and out with cold water and don't dry it, then stand it upright in the freezer for at least 30 minutes (an hour for a heavy mug). The water clinging to it freezes into the white frost you're after. For a quicker version, wet the glass and pack the outside with crushed ice for a few minutes. There's a real trade-off, though: hard freezing is great for mass-market lagers you want bone-cold and refreshing, but for craft and aromatic beers most brewers and bartenders advise against it, because ice-cold temperatures flatten the aromas and hops and can create off flavours, and condensation waters the beer down. For those, chill the glass only briefly in the fridge, or serve it at cool cellar temperature. Keep dedicated beer glasses away from strong-smelling food in the freezer, since glass picks up odours." published: 2026-07-09 updated: 2026-07-09 ---
