It’s a very smooth black tea, especially for Adagio (I’ve always found their tea to be a bit bitter and drying). The blackberry taste is definitely present. I don’t know if I would be able to identify it as blackberry, but it blends with the black tea base very well. The vanilla is detectable in the smoothness of the sip. I can’t really taste it otherwise. There is a tiny bit of astringency which adds a nice tartness to the blackberry note. I wonder what a little splash of milk will do to the flavors. Overall, a very fun tea! I might be popping this in my shopping cart in my next Adagio order. Thank you so much, SimplyJenW for a sample.
