§ 04 — The terroir

Three metres of iron and sand.

Terroir usually gets talked about as one thing. Here it is three: the sand that drains within the hour, the iron-rich clay that holds water into July, and the sea that drops the temperature by thirteen degrees at six in the evening.

0 — 30 cm Yellow sand Drains fast: after an August storm the water is gone within the hour.30 — 90 cm Sandy clay Where most of the roots of the young vines sit.90 — 180 cm Iron-rich clay The iron the estate is named after. Holds water right through July.180 — 300 cm Limestone skeleton Only the 1961 vines reach this far — which is why they survive the drought. Sèrrone — section Survey of 12 March 2024, pit dug to 3 m

§ 04.1

Four readings

Estate weather station, 2015 — 2025 averages.

Annual rainfall

612 mm

Nearly all of it between November and February. It does not rain in summer, and every decision assumes that.

Days above 35 °C

31

It was 18 in 2015. This is the number that made us move pruning and rethink canopy height.

August day–night swing

13,4 °C

The evening sea breeze arrives at six and cools the bunches: that is what keeps the acidity up.

Distance to the sea

0,8 km

At the lowest parcel. Salt settles on the leaves by late summer, and you taste it in the glass.
