Pairing on acidity

Pairing on acidity aligns a wine's vivacity with that of a dish, since a tart plate demands a wine at least as taut so it does not seem flat. A fish sharpened with lemon thus suits a dry, nervy white. A wine's acidity also acts as a rinse, cutting through fat and refreshing the palate between mouthfuls, which makes it a major lever in the sommelier's toolkit at the table.
