After some effort I have finally arrived at the optimal brewing conditions for this tea. The taste is definitely reminding of an artichoke. The full spectrum appears very fast in the first steep, that is if the temperature is right. Too hot, and the brew tastes bitter and grassy. But steeped properly it is very attractive taste. Dry leaves smell very much like green chypre perfume with the high notes of galbanum, hyacinth and magnolia leaves. Overall quite seductive.
