A crisp, refreshing Chablis (unoaked Chardonnay) pairs wonderfully with crab. Its bright acidity and subtle minerality enhance the sweet, delicate flavors of the crab without overpowering them. Alternatively, Albariño or Sauvignon Blanc also work beautifully, offering citrus and floral notes that complement the briny, fresh taste of crab.
