The Effects of Storage Conditions on Tea Quality: A Delicate Balance!
by Dr. Saziye Ilgaz (June 2025)
Tea stands as one of the most cherished beverages worldwide, enjoyed not only for its rich flavours and aromatic nuances but also for its myriad health benefits.
Each sip of tea consumed with pleasure is the product of a delicate balance between storage conditions and tea quality throughout the journey of tradition and science. During this journey, different varieties of the Camellia sinensis tea plant are processed into different types of tea and stored under appropriate conditions until consumed.
Storage refers to the methods and conditions used to preserve the quality, flavour and freshness of the product over time. The storage process in non-oxidized (green tea, white tea), semi-oxidized (oolong tea), and oxidized teas (black tea) is important for preventing spoilage, preserving nutritional value, and maintaining desired sensory characteristics. However, this process has a distinct significance for the final quality development and maturation of fermented teas such as pu'erh and kombucha.
