Loire Valley Sauvignon Blancs, especially from Sancerre and Pouilly-Fumé, are known for their mineral-driven and citrusy profiles, often with a flinty, smoky character. In Bordeaux, Sauvignon Blanc is often blended with Sémillon and sometimes aged on lees or in oak, resulting in a richer, fuller-bodied style with flavors of honeysuckle, white peach, and beeswax.
