Mouth Watering Wine
To set the stage, I think it is important to understand what acids are present in wine, and their role in the enjoyment of the wine in your glass. All wines contain acid. When we taste wine, we experience acid on the sides of our tongues, and the mouth watering affect it creates. Acid is one of the components that a wine taster will be evaluating while sampling wine. Acid refreshes and cleanses the palate.
My second experience of the week was during one of my wine classes for the International Sommelier Guild. During class, we sampled a bottle of Arneis from the Piedmont region of Italy. This white grape has traditionally been added to Nebbiolo to soften the acids and tannins. Arneis is a perfumed white wine, that is very low in acid. Because of this low acidity, the wine tastes somewhat flabby. That refreshing, palate cleansing acid is absent. It didn't spring out of the bottle, and left me disappointed with the wine in the glass.
