Our 4 best methods
Keep a few frozen grapes in the freezer to chill wine with when needed. Put 1-2 grapes in the glass or 6-8 in a decanter. Certainly not everyone's cup of tea, but very quick and especially recommended for a spontaneous aperitif.
Salt and ice
Put ice cubes in a bucket or sink, sprinkle generously with salt, and add ice-cold water. Professionals call this method «frapping.» It is important to rotate the bottle every few minutes so that the wine cools evenly.
Cloth and freezer
Wrap the bottle in a damp paper or cloth kitchen towel and place it in the freezer. It's best to set a timer so you don't accidentally freeze the bottle. It is recommended to gently swirl the bottle every 5 minutes.
Special kitchen utensils
There are cooling sleeves in all shapes and colors for sale, as well as special aerators with cooling rods. They don't cost much and are certainly a worthwhile purchase for wine fans. Both must be placed in the freezer early - preferably permanently.
