“You can really taste the flint here.” You hear it at every other tasting — and it describes something that does not happen. No vine draws chalk, gravel or flint out of the ground; no wine carries the taste of rock into the glass. “Minerality” may be the most used and most misunderstood word in wine. And yet the impression is real — it simply comes from somewhere quite different than most people think.
Rock, salt aside, has no taste, and the minerals that travel from the soil into the vine are far too few ever to be tasted. Two things are real all the same. One is a scent: that whiff of ground flint and struck match you catch at once in a great white Burgundy. It comes not from the rock but from a reductive, low-oxygen ageing in the cellar. The other is a feeling in the mouth: coolness, tension, a pull towards the saline, a freshness that keeps the wine upright. That freshness is readily put down to acidity — too simple: a sharp, high-acid wine can still taste flat, while another carries the same tension with less acid. The more interesting question is where it truly comes from.
The answer does lie in the soil — but not as flavour, as water. Because we do not irrigate, the ground alone decides how much water a vine has through a dry summer. A lean, gravelly soil holds little back; the vine has to ration, makes smaller, thicker-skinned berries, and the wine turns tauter, clearer — what many call “mineral”. A soil that stores water supplies more generously, and the wine comes out rounder. It is not the stone that makes the tension, but what the stone demands of the vine.
This flinty character can also be sought on purpose — and that is exactly what we do with our reductively made white wines, the Caprice and the Intermezzo. It begins with whole-bunch pressing, which keeps coarse, bitter compounds out; then a slow, cool fermentation and a long ageing on the fine lees, which give the wine texture without our stirring them; and above all as little oxygen as possible — barely any racking, a quiet barrel. Out of this reduction comes the note of wet stone and struck match: craft, not chance — more handwork than stone in the ground.
Read this way, “minerality” is an honest word: it means a scent and a tension made in cellar and vineyard — not the taste of stone. Whoever knows this listens more closely at the next glass, and trusts their own impression a little more than the label.
