Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I love this rice for making sushi frequently. So far I have been buying the smaller bags. This time I ordered the 15 lb bag as it is cheaper per pound. The bag arrived ripped open with rice everywhere on the porche, in the box and everywhere else. I think the bag is too delicate for this size. Other than that I love this rice and would give it 5 stars.
