Organic tea is produced using methods that meet the standards of organic farming, which strives for ecological balance and the preservation of biodiversity. Tea can be grown organically by the farmer, but it does not have a quality mark because the farmer has not applied for it. This may be because the process to an organic quality mark costs time and money. Farmers regularly opt for organic cultivation simply because chemical fertilizers and pesticides cost money. HAO TCHA tea does not have a certification for organic cultivation. The Empress Oolong, Oriental Beauty Oolong and Honey Black are teas that are not sprayed to invite the Jacobiasca formosana grasshopper to visit the plantations. Without biting the leaf of the tea plant, these teas do not develop their unique honey flavor.
