Personally, I find this tea tolerable only if I prepare differently than I prepare my standard cup of Earl Grey. I usually add a capful of Lemon Juice (or one wedge), with two tea bags in a standard mug.
I add the Lemon to bring out the Bergamot, however with Stash this is for some reason unnecessary. I am not very fond of it, but it will do in a pinch. It’s flavor is sub-par in my opinion, but its definitely not terrible.
(NOTE- I like my tea very bitter. I never take black tea with cream.)
