So, how do you know if your champagne has gone bad? Well, there are a few signs to look out for - like a flat or stale taste, or a yucky smell. It's like when you leave a carton of milk out too long - you can just tell it's gone off.
And, if you're still unsure, you can always check the bottling date - most champagne bottles have one. It's like checking the expiration date on a carton of eggs - you just want to make sure you're getting the best possible product.
But, at the end of the day, it's not that hard to keep your champagne fresh. Just store it properly, and you'll be enjoying a cold glass of bubbly in no time - cheers to that!
