Not in the kitchen or garage! The temperatures are too variable.
If you are going to store it at home, make sure it is in a cool, dark place with a constant temperature. Between 8 and 13 °C is ideal. The wines should be stored lying down and avoid any vibrations. If you don’t have a cellar under your house or haven’t invested in a fancy wine fridge, the best place to store your wine is in a wine warehouse. These cost around £10 per case per year and your are assured of the ideal conditions. It also stops you being tempted from drinking a bottle at the end of a heavy night and regretting it the next day.
