I have bought today a loose Ahamad Earl Grey in Tiv Taam store in Israel. It is the first time I do so.
I brewed it as per the instructions and got even worse taste than Israeli Wisotsky tea, which, to this day holds the absolute low of Earl Grey teas I tasted. So I went to search what others say on the Web and found your review. Whether you got a faulty product or not, my experience confirms your review.
