I let this steep for 5 minutes in the Yixing and I knew what to expect. A strong, dark very flavorful brew. No rinse. This went straight to my head. I could feel this tea immediately. I noticed a vast improvement since my last tasting. I have several young Shu such as this that I will sip from time to time to see how they are aging. This one is getting there. Another raising of the score….
