Walnut

A drier, slightly tannic nut note that shades towards bitterness — and one that can indicate a roast pushed slightly too far.

Walnut in chocolate reads differently from hazelnut or almond: drier, more astringent, with a faintly bitter edge that comes from the same tannin-like quality real walnut skins have.

It is worth watching, because it sits close to the boundary where roast character stops being pleasant. A bar described as walnut-like is often a bar whose roast has been pushed a little past its optimum.

Descriptors used
walnut, pecan, walnut skin, dry nut
Desirable?
Acceptable in moderation and a warning sign in excess — it sits close to the over-roasting boundary.

Where it comes from

More than one route produces this note. Each entry says how to tell it apart from the others.

  • Created during roasting

    Inferred

    Later-stage Maillard development produces drier, more astringent nut character than the earlier hazelnut-like phase.

    How to tell: Walnut character arrives with a drying finish. If it is accompanied by any ashy bitterness, the roast went too far.
