...tea bags in the cupboard for a few years they lost their flavor. I am assuming that part of this is due to volatiles which give flavor to the tea migrating out of the tea and into the air.
When I open my tea cupboard, which is filling up with sheng, I smell a delicious smell come rolling down. It is most noticeable when the humidity is higher (I use a cup of hot water to humidify and do not have a hygrometer).
Does the presence of the rich aroma mean that the tea is losing flavor components into the air, and my tea is diminishing in quality, or does it mean that the microbes are doing their job and my tea is improving?
