The following scale is used on to assess the quality of wine:

Outstanding and Very Good wines are wines that are highly recommended.  Buy them if you can.

Good wines are just that - well made and won't disappoint.

Acceptable wines are everyday or unremarkable wines that are fault free.

Poor means that I didn't like the wine.

Faulty means just that.  Cork taint and oxidation are common causes.

The descriptions of the wines are more important than the scale.
