Definitions for "Yeasty"
A wine taster's term for a wine that has a pronounced flavor of yeast. Reminiscent of fresh bread, this flavor is common in sparkling wines and wines aged "sur lie." For all other types of wine, this flavor should be considered a fault. It should never be too pronounced, and in sparkling wines, it should be more toasty (like burnt bread) than a freshly baked loaf.
The fresh/pleasant smell of fermenting yeast is called yeasty.
