Honey does not expire. Its active microbial properties make it safe for consumption indefinitely as long as it is not contaminated by other means. Honey has even been recovered from ancient tombs such as those of the pharaohs of Egypt in perfect condition. Food safety standards usually recommend consuming manuka honey within three years of opening the jar. Don't panic if your honey starts becoming cloudy and has a thick crystally texture. It still has health benefits, and it's still going to be tasty to eat.
