The science behind keeping a beer cold for over an hour.
Your beer doesn't warm up because the air is hot. It warms up because the bottle glass is constantly absorbing heat from your hand, the table, and the room — and then transferring it straight into the beer.
COLD1™ wraps the bottle in a sleeve of phase-change material that's been pre-frozen solid. As it absorbs heat from the glass and slowly melts, it pulls energy away from your beer instead of letting it warm up. The result: an ice-cold pour for 60+ minutes, with no ice cubes, no melt, and no watery lager.
If "my beer gets warm too fast" is a sentence you've ever said out loud, COLD1™ is the simplest fix you'll ever buy.
