Osmanthus tea can be divided into two types: fragrant tea and fragrant tea. Fragrant tea is not suitable for long-term storage, while Luzhou-flavor Chaze is suitable for long-term storage. No matter what food has a shelf life, osmanthus tea is no exception. Its shelf life is two years, but generally speaking, the best drinking period is about six months to one and a half years after production. It began to decline after two years, and some of them were well preserved and could be drunk after two years, but the quality of tea could not reach the original level.
