Can you eat rowan berries? Raw, fresh berries are the ones most likely to cause trouble
The berries in the photograph are rowan berries and look fully ripe in early September. The main question is not simply whether they can be eaten, but how you intend to eat them.
These are berries from a rowan. They are not poisonous in the usual sense, but as you are asking about eating them raw and fresh, it is worth being clear: they are usually bitter and astringent, and larger quantities can irritate the stomach.
The berries can be good to pick in early September, but are usually more palatable after the first frost or a day in the freezer. That softens the flavour somewhat, although they are still rarely berries to snack on straight from the clusters.
They are therefore best used in jelly, jam, cordial or preserves, often with sweeter fruit such as apples. If you still want to try them raw, taste only a few at first and notice how your stomach responds.
