Why it works
Tom yum is one of the sharper pairing tests because it combines acid, heat, herbs, and shellfish. Off-dry Riesling works here because its gentle sweetness, low alcohol, and bright acidity cool spice, flatter salt, and refresh rich sauces. That makes the match feel deliberate: cooling chile heat with gentle sweetness and lower alcohol, avoiding the burn that comes when high alcohol meets chile heat, with the wine refreshing the next bite rather than stealing the spotlight.
