Just bought some beer and it's still lukewarm?
To cool a beer in a few minutes, there is a technique that can save your aperitif.
Just wet some Sopalin and wrap it around the beer, then put it in the freezer.
It will be fresh barely 15 minutes after you return from the supermarket.
1. Take two paper towels.
2. Wet them without bending them.
3. Surround them around your beer.
4. Put your beer in the freezer for 15 min.
There you go, your beer is already cold :-)
All you have to do is taste it... in moderation of course!
