Do bitters go bad? The science behind expiration
– Bitters can be stored in a cool, dry area away from direct sunlight and heat
– Fruit-based bitters may need to be kept in the refrigerator
– Excess bitters can be used in jams, marinades, dressings, and dips
– Bitters are made by infusing herbs, fruits, bark, spices, seeds, and other ingredients into a neutral spirit
– Most bitters have a shelf life comparable to any spirit, essentially indefinite
– Some fruit bitters made by Fee Brothers may have a shorter shelf life if made with glycerin instead of ethanol
