Breadth of the Variety
Riesling is an extremely versatiles grape capable of producing world-class wines in all styles from bone dry to sparkling to intensely sweet. No other grape is able to express itself through this full stylistic spectrum with such grace and competence. Riesling is able to do so both because of its high natural acidity and potential to develop high sugar levels.
For wine, acidity is a great ally. Acidity is a natural preservative allowing wines to age and develop more gracefully (and longer) in the bottle, while providing the structure or backbone around which the wine is built. Acidity also provides a counterpoint to sweetness and has a balancing effect upon wines that are made with measureable residual sugar.
When we drink wine, acidity provides our palates with a sensation of freshness, brightness and liveliness. The acidity cleanses our palate when consuming food, helping to keep us interested in both what we are eating and drinking. Wines without sufficient acidity can appear dull, boring or flat, or as if nothing is there to hold them together (lacking balance and harmony).
There's a Riesling to fit any situation and circumstance - to pair with cuisine as diverse as the lightest seafood and salads to the richest meat dishes and complex dishes to even sweet desserts. The fun challenge is discovering the right Riesling for a particular food or occasion.
