FODMAPs present
Low-FODMAP serving
2 grapes (about 10 g)

Re-tested with a sharply smaller serve: a couple of grapes are fine, but a normal handful is high in excess fructose — treat them as a garnish, not a snack bowl.
Seen a different rating somewhere else?+
Usually it's a portion difference, not a disagreement. This page scores grapes at a serving of 2 grapes (about 10 g); at 3 grapes (about 15 g) or more it belongs in the high band. A source quoting the larger serve will call it high, and one quoting the smaller will call it low — the same food, measured at two different amounts.

How much is OK?
This food's verdict depends on the serving. The bands below show where the load builds, group by group.
Excess Fructose
A dramatic re-test result: the serve dropped from a generous bunch to a couple of grapes, with excess fructose arriving from the third grape. Colour makes little difference — treat all table grapes the same.
Bands reflect published FODMAP research for typical preparations — individual tolerance varies, especially mid-reintroduction.
