Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I am impressed with many products from Dilmah, Rose and Vanilla, peppermint, Italian almonds. But this one is weak with jasmine flowers, not as fragrant as expected after using two bags in one 1.2l tea pot. Green tea side is OK.
