Our last stop during our trip to China in 2019 was up to Gulou in Hunan Province. Xiao. She has run it for the last 13 years and built a beautiful garden that makes great tea. Green Gulou comes from tea plants carefully tended in the steep hills above the factory. These traits come from the umami found in the young tea leaves. The tea is fixed green, rolled, and dried in ovens to preserve its sweetness.
