What this weather does to the fruit.

Five readings from the recorded season, each against the band the crop does best in (painted green on the dial). The meanings are what growers and agronomists expect of weather like this, not a tasting note.

Heat over the season · in balance

Enough heat to ripen fully without tipping into heaviness.

Day–night swing while ripening · ideal

Cool nights after warm days keep acidity and aroma while sugar builds — the signature of a classic year.

Rain in the last 45 days · wet

Late rain swells fruit with water and tends to dilute flavour; it also brings rot pressure.

Sunlight · brilliant

Light builds colour, skin ripeness and sugar.

Days above 35° · none

No heat stress: the plant never shut down to protect itself.

The season, as it happened.

1 April 2010 to 15 October 2010, recorded daily at 44.61°, 7.94° (ERA5 reanalysis via Open-Meteo historical archive). Choose a chapter to mark it on the paper.
