Decided to do a side by side taste test at the tea party today. My youngest loves this Keemun but likes really mild tea for the most part. The Harney and Sons version was more aromatic, more robust, and darker. Although Harney says it is a little more astringent than some Keemuns it was not too astringent for me. I would give it a 1.5 of 5 for astringency! I do not care for astringent or bitter teas. The tea is mild to a fault in my opinion. If you want a good all around tea to serve to a group of non-tea-drinkers this might be your tea. But if you love good, strong, cocoa-y Keemuns, look elsewhere.
