Aged tea. Lao cha
In China, Lao Cha (aged teas) is treated as collectibles, the subject of pride for a true "tea man", gourmet and connoisseur. Collectors of aged teas are especially numerous in Taiwan, where there is an official Community in which they are united. This community produces catalogs, holds auctions and competitions.
There are no clear boundaries beyond which "Lao" begins. The maturation of tea is influenced by many nuances: the characteristics of raw materials, the type of tea, the place of its growth and the storage conditions. With a lucky coincidence of circumstances after reaching 3 years of age, the tea can already fall into the category of aged. Mainly this applies to white varieties, sheng puer and those oolongs that are warmed up on the coals during the ripening period.
