- wine judgement
The Roman formula for tasting is known as COS (colour-odour-sapour), referring to the colour, aroma and taste of wine. Today wines are still tasted in this method. In many cases, we also find rating systems that make it easy to compare the visual quality of wines. The 20 point rating system used to be popular, yet an increasing number of magazines and wine journalists are using the 100 point system. See also degustation and tasting.
