encépagement, widely used French term for the mix of cépages, or vine varieties, planted on a particular property. These proportions (typically for a médoc estate, for example, Cabernet Sauvignon 60%, Cabernet Franc 20%, and Merlot 20%) do not necessarily correspond to the proportions of each grape variety in a given wine, partly because different varieties vary generally in terms of productivity, but also because factors such as flowering and frost may dramatically influence the yield from each variety in a given growing season.
