Sweet chestnuts: where they fall and when they are gathered

Autumn's fruit in the groves of the north and the mountains of the south. It falls on its own, and every valley has its week.

A burr split in three and its chestnuts on the litter of the grove: the glossy shell, the pale scar at the base and the dry tuft at the tip.

The sweet chestnut (Castanea sativa) comes out from September to December, at its best in October, in woods of sweet chestnut, from low ground up to the middle mountains. It is also known as chestnut, Spanish chestnut.

See where it is ready this week

Right now, the best day forecast for sweet chestnuts is 30 October.

The sweet chestnut has been in Spain for two thousand years, and almost always someone planted it: the groves of Galicia, El Bierzo and Asturias, Las Hurdes and the Sierra de Francia, the Genal valley and the Serranía de Ronda. Under every old tree lies an acid soil, damp in autumn and clean, which is exactly where the burr splits open and drops the fruit.

The gathering is ruled by height and by how far north you are, not by rain or waiting. In the Genal it starts in late September; in Galicia and El Bierzo, around the middle of October; in the high groves of Sanabria and O Courel, in November, when the chestnut-roasting nights fill the villages with smoke.

Two warnings worth more than any date. The fruit of the horse chestnut, the tree of city avenues, is not eaten: it is neither the same tree nor the same burr. And a chestnut grove is rarely unowned: most Spanish groves have an owner, and many councils set the week when gathering begins.

What the date depends on

No rain sets it off and no waiting counts: the fruit ripens at its own pace and falls on its own. The week changes from one valley to the next, coming earlier in low country and in the south, and later the higher and the further north you go.

Where to look

It comes out in woods of sweet chestnut, from low ground up to the middle mountains, always on acid soils.
