Green teas undergo less processing than black teas. Green teas are completely unoxidized, and instead the freshly plucked leaves are fired (heated) as soon as possible after harvesting to halt any oxidisation. Once dried they are then sorted and graded, ready for brewing. By their very nature, green teas are much lighter than black and are rich in antioxidants, making them the tea of choice for many health-conscious consumers. Green teas should be brewed at a lower temperature than black (85 degrees is an ideal average) and should never be drunk with milk.
