French wine terminology for “medium-sweet” wines is “Demi-Sec.” Demi-Sec wines are sweeter than “Sec” wines but less sweet than wines labelled as “Mouelleux” or “Doux”.

Specifically Chenin Blanc wines from the French wine areas of Anjou, Saumur, and Touraine as well as some sparkling wines (champagnes, crémants) are referred to by this word in everyday usage and on wine labels.
