Many sites publish customer reviews. Usually 1 - 5 star. As zero is not available this means that 1* is anything from 0 to 20 % satisfaction.

Tesco are asking for reviews of their groceries including wine but not publishing them. Seem they are in the process of introducing them.

Others have reviews dating back 2 or more years. Products have changed, suppliers change and vintages change. Need to look carefully.
