Green, Sencha okumidori
some random Chinese oolong
White, bai hao yin zhen
Edit: The oolong was pretty good. Mildly floral and fruity. The okumidori was just as good as I expected. Worth the price IMO.
Boutique teas are really low margins
On what basis are you making this claim?
That said the conclusion stands regardless. Only some shops stock these teas.
