Bu Zhi Chun is a rare wuyi tea, whose name translates "Never Knows Springtime", and is also known as Dong Pian, or "Winter Sprout". During the winter season, every so often, the weather warms just enough to trick the plants into growing new shoots. These leaves are quickly harvested before the cold weather returns, with the shoots never seeing springtime weather. Less exposure to sunlight during winter encourages a higher theanine content in the leaves, which contributes to the silky sweetness. A medium level roast further brings out the delicate sweetness which temper well with the woody characteristics of aged maturation.
