Wines that go with oily fish, like salmon or mackerel, should have high acidity and bright flavors to cut through the richness. Look for crisp whites like Sauvignon Blanc or Grüner Veltliner, with notes of citrus, green apple, and herbs. Regions like Marlborough in New Zealand and the Loire Valley in France produce excellent options. For a twist, try a light, chilled rosé to elevate the pairing experience.
