How long should a bottle of alcohol be left open before it gets spoilt?
People often wonder how long alcohol remains good after opening the bottle or making a drink.
Let us tell you how long a peg of whiskey, wine, or beer takes to spoil if left aside.
Wine starts losing its taste soon after opening and is usually considered bad after five days.
A peg of wine spoils faster than the bottle, as more air enters and accelerates oxidation.
However, this applies mainly to red wine; sparkling, white, or rosé wine spoils within 2 days.
Whiskey has a higher alcohol content, so it doesn't spoil as quickly as wine.
If a can of whiskey is left open for hours, its taste may change slightly due to air exposure.
Exposure to air (oxidation) can gradually alter the aroma and taste of whiskey over time.
If left open, dust, insects, or bacteria from the environment may enter the whiskey.
If beer is left in a glass, it becomes unfit for drinking within a few hours as its taste deteriorates completely.
However, if open beer is kept in the refrigerator, it can be consumed later, though the taste changes.
Once opened, the beer is exposed to air, which leads to oxidation.
Foam in beer is mainly caused by carbon dioxide, which dissolves in the beer during fermentation.
It evaporates once the beer is opened, which is why beer loses its taste after some time.
