Walnut

Juglans regia · Juglandaceae (walnut family)

Walnut
Rich, buttery and faintly bitter — that bitterness is in the skin, and it is what distinguishes walnut from almond in a blend. Two products carry it. Like the almond, it is not a true nut: walnuts are drupe-like, because the outer covering of the fruit is technically an involucre.

Its story

Where it comes from

The Persian or English walnut, Juglans regia, originated in Iran. World production in 2023 was four million tonnes in shell, with China contributing 35 per cent, then the United States, Iran and Turkey. Our lot names no origin.

What happened

The wal in walnut is Germanic and means foreign — the foreign nut, as distinct from the native hazel. That is a small piece of linguistic history that tells you where the tree came from and how long ago it arrived in northern Europe: long enough ago to be familiar, recently enough to still be marked as an import. Walnut husks contain juglone, at 2 to 4 per cent of fresh weight, which is why little grows underneath a walnut tree.
