Described as a First Grade version, I thought it would be better to do a side-by-side comparison with my standard ZG71 Superfine from Upton.
First off, the dry leaf in the opened tin didn't have an aroma while the tea from Upton has a thoroughly noticeable smell. Brewing both w/ 1 tsp. in 8 oz, 165F for 2-3/4 min. yielded liquors of the same color, but the Adagio didn't provide the scent and sipping a teaspoon didn't yield a flavor close to the Upton's Lung Ching so, I continued the infusion to the recommended 3 min.
It didn't help. Described as "refreshingly smooth, sweet and delicate," it left an appalling aftertaste reminiscent of the decaf green tea from Celestial Seasonings that I once brewed up way past the expiration date.
I immediately dumped both the liquid and the contents of the sample tin and am now sipping more of the Upton to remove the bad experience from my mouth.
