First, lift the wine glass from its stem. Take care not to touch its bowl, since you dont want any fingerprints. And then, see. Hold it against a bright white backgroundthe ceiling or a wall should doand observe its clarity. Particulate matter of any kind is unacceptable. Then, observe the colour. Assess its richness, evaluate its depth and focus, particularly at the top rim of the liquid. For red wine, the brighter this rim, the older it is. For whites, darker is older.
