Many brands now offer a white tea--Buy Tea

So the issue of quality is not really about the grade that we choose, but the actual tea we buy within that particular grade. We may choose to drink a White Peony because we enjoy that style of white tea, but we should distinguish its quality by comparing it with other White Peony teas. Many brands now offer a white tea called White Peony, yet the quality of White Peony offered by brand X is not necessarily the same quality as brand Y. Factors that determine its quality such as the time of harvest, the age of the trees, their environment, and the proper processing of the leaves are not indicated by its name.
In understanding how to determine the quality of white tea, we should first appreciate that generations of tea masters have enjoyed white tea for its taste and texture long before scientists began chemically studying white tea for its health benefits. High quality white tea is an exquisite style of tea that has held a position in every list of prized Chinese teas by almost every tea master. Its unique flavour profile has gained white tea its esteemed status. It is ultimately in the taste and texture that we determine its quality.
Bill Lee advises, "Look for a traditional white tea that tastes like a white tea. Silver Needles should be tender, supple and serene with a sweet touch. A White Peony should feel comfortingly warm, fresh and crisp like a welcome breeze on a warm spring day." However, many inferior white teas taste too grassy with a harsh texture. White teas that taste too grassy are inadequately/improperly withered and often resemble coarse green teas.
White tea is a distinct category of tea that is processed differently than Buy Tea. Its unique method of processing creates its warm refreshing character. The freshly harvested leaves are ideally allowed to wither under the sun, then transferred indoors, and finally dried under low heat. Traditional white teas that are prized by tea masters are not steamed or pan-fired to inactivate the enzymes before withering, and are not rolled for fermentation. If white teas are steamed or panned before withering, they will begin to resemble green tea production and taste. The process of crafting white tea can be very simply described, but its control and perfection is far from simple.
