What’s the difference between passive and active wine cooling?

Passive coolers, like sleeves, simply insulate the bottle, slowing down warming. Active coolers, like Coolenator, have a frozen core that actively draws heat away from the bottle—keeping it colder, for longer, without needing ice or power.

How long should I chill my wine before serving?

It depends on the type. White and sparkling wines usually need 2–3 hours in the fridge, while reds benefit from just 20–30 minutes of chilling. Once opened, a wine cooler helps maintain that temperature without the need to rush or re-chill.

Can I store my wine in a wine cooler overnight?

Wine coolers are best for short-term use during serving. For longer storage, a wine fridge or cellar is ideal. But if you're finishing a bottle the next day, keeping it in a wine cooler (with the core refrozen) for a few extra hours is a practical short-term solution.
