Pomace (/ˈpʌməs/ PUM-əs), or marc (/ˈmɑːrk/; from French marc [maʁ]), is the solid remains of grapes, olives, or other fruit after pressing for juice or oil. It contains the skins, pulp, seeds, and stems of the fruit.

Grape pomace has traditionally been used to produce pomace brandy (such as orujo, grappa, zivania or törkölypálinka) and grape seed oil. Today, it is mostly used as fodder, as fertilizer, or to extract bioactive compounds like polyphenols from it.
