I am planning on bottling pre-mixed cocktails as party favors for a party that I am hosting (2 ounce bottles). The cocktail has alcohol, bitters, and also simple syrup. I am curious how long the mixture can be stored for. I have read that simple syrup can go bad, so I just wanted to make sure that these little bottles won't have a short expiration date.
Does anyone have an idea about that?
(Oh, and $10 off your order of $50 or more in the Food52 Shop, too.)
