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 Grapes icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
