Exercise your sense of sight

First learn to observe effervescence:

pour different sparkling drinks (mineral waters with different degrees of carbonation, beers, sodas, etc.) into identical, clear glasses set against a white background. All the bubbles are not the same. Their size, their speed, their quantity, the mousse on the surface, all vary from glass to glass.

Next, assess the visual quality of each liquid:

Is it bright, glittering, shiny, or dull?

Now look at the colour:

pour two or three different fruit syrups (like peach, lemon or apricot) into different glasses of carbonated water, with different degrees of concentration. Then try to find the most appropriate word to describe the colour in each glass. Later on, when you do this exercise with Champagne, you will discover how much the variation in colour tells you about the personality of each wine.
