Two principal varieties of tea bush are used in tea making – Camellia sinensis var. sinensis (China bush) and Camellia sinensis var. assamica (Assam bush). Which variety is used plays an important role in determining taste and appearance, but it’s not the only factor.
The growing conditions are equally important. Every tea crop is hugely affected by temperature and rainfall, shadow and light, and the quality of the soil and water. Just like wine, tea can taste vastly different region to region, year to year and even week to week. And then, of course, there is the tea making process itself.
