Autumn 2015 version here.
This one has slight a lemon flavour in there, and as AllanK found out can turn sour if overbrewed, from lemon to lemon zest. In fact I completely agree with the other notes mentioned in his review, there is some vegetal in there and the standard white floral, also slightly astringent, with an aftertaste & an after-smell (is there even a word for that?) which just somehow reminds me of lemon cleaner or zest.
Im going to refine my brewing to find the perfect setting for this tea & will update this review when ive found them.
Flavors: Astringent, Floral, Lemon, Lemon Zest, Vegetal
