Step 1 - Pour approximately 75ml of serving into a wine glass.

Step 2 - Angle the wine glass over a white backdrop, and under natural or white lighting to inspect the colour, opacity and hue at the rim of the wine glass. Various wine differ in colour, intensity and hue depends on the type of grape variety, production and age.  

Step 3 (Optional) - Swirl the wine to see the viscosity in the wine glass. Viscous wine have higher alcohol and/or residual sugar content.

Note: Wine legs/tears is a phenomenon caused by fluid surface tension created from evaporating alcohol. Sediments are particles left behind by unfiltered or aged wine, and they are harmless.
