                                Matcha's vivid green color and distinct flavor are indications of its freshness, but as a finely ground powder with a large surface area, matcha is highly susceptible to environmental factors. The short answer to 'does matcha lose its potency' is yes, and it happens more quickly than with traditional loose-leaf teas.
