Sparkling wines should be stored in a cool and dark place. Your fridge is the best place for this, as the temperature should not be more than 10ºC. The humidity should also not exceed 10ºC. The humidity should also not exceed 70%. Sparkling wines do not tolerate temperature fluctuations.
The environment should be as odourless as possible. Fuel oils or solvents will be reflected in the taste and can spoil the drink.
If your laundry room or the place where your washing machine is located is nice and cool, this place is also not suitable for your sparkling wine. Sparkling wine cannot withstand the vibrations of the washing machine, for example during the spin cycle.
It is important that you store sparkling wine upright. Otherwise, the characteristic tingling sensation can be lost.
