At Northwest Wine Report, I use the 100-point system to rate wines. Here, this is truly a 20-point scale, using the descriptions below as a guide.
The 100 point system has dominated wine ratings in part because it is familiar to many people from their school days. I have therefore also given what I see as the “letter equivalent” in terms of scholastic ratings. Note that the numerical ratings and “letter equivalents” do not always align. For example, an 80 is not a particularly low academic score. But an 80 is quite a low score for a wine.

Special Designations
In addition to the ratings above, a subset of wines also receive certain special designations. These are based on the following criteria.

Why only a 20 point scale?
Most wine review sites say they use a 100 point scale. However, publications that have categories for wines below 80 points very rarely use them. In fact, many publications don’t score or publish wines below 85 points.
Here, I consider wines rated less than 80 points not commercially acceptable. That is to say, they have at least one significant flaw or fault. Personally, I do not believe there is consumer value in parsing whether that lack of commercial quality equates to a 79 or a 59.
