My point systems contains 10 categories: from very bad up to 8 points!
The conclusion of points is subjective and driven by my personal taste. But it does reflect also a ratio of cost and performance of value. This said, sometimes I may give a bit higher quote if something is really affortable, in particular if it concerns wine.
Here is the explanation of my point system:
|8||best and outstanding|
|very bad||very bad|
