Sémillon (say “seh-mee-YAWN”) comes from Bordeaux in southwest France, and you’ll most often meet it as a blending partner with Sauvignon Blanc in “Bordeaux-style” whites.
It can show up in two very different moods: dry (soft, citrusy, gently waxy) or lusciously sweet when the grapes get a helpful natural fungus called botrytis (also nicknamed “noble rot”), which concentrates flavors and creates famous sweet wines like Sauternes.
In Napa and Sonoma, Sémillon is around, but it’s less common than Chardonnay or Sauvignon Blanc, so it’s a fun one to recognize when you spot it on a tasting list.
