The part that makes the difference

The cooling is in the bullet.

The reusable freezer bullet sits inside the insulated Coolenator body. Once frozen, it provides the cold that keeps your chilled bottle cool.

When the evening is over, put the bullet back in the freezer and use it again.

Good to know

A few practical answers to help you get the best from your Coolenator. Before your first bottle.

What is the difference between the Classic and the Tall?

The Classic holds the lower half of the bottle, so the top stays in reach for pouring.

Which bottles fit?

Most standard wine, champagne, and cava bottles fit snugly inside.

Does the bottle need to be cold first?

Yes, for best results put a pre-chilled bottle into your Coolenator.

How long does the bullet need in the freezer?

We recommend keeping the bullet in the freezer for at least 6 to 8 hours before use.

Where do you ship from?

All orders are shipped directly from our fulfillment center.
