How to Tell if Brandy has Gone Bad?
In terms of food safety, brandy (burnt wine) does not expire. Brandy is manufactured from fermented fruit mash and then distilled into strong, concentrated alcohol before being bottled at a stunning 35 to 60 percent ABV, compared to 11.6 percent for wine. Because of the high alcohol level of the spirit, it can be preserved indefinitely without the risk of germs or other infections forming. It’ll also be perfectly safe to eat.
On the other hand, while brandy can be stored eternally without expiring, its flavour and quality will not be the same as when opened.
