It's an icon of a bunch of grapes with a short stem still attached. The stem is at the top and cut off at the very top, where there are eight circles evenly spaced representing each of the hanging grapes.
This icon is a part of a collection of Grapes flat icons produced by Icons8. Icons follow the guidelines of iOS, Windows, and Android and are designed by a single designer, guaranteeing the consistent quality.
