The season, measured

Climate parameters that shape fruit quality

At Verdú the acid comes from cool nights. Over the same 171 days the vineyard ran 1.1 °C cooler after dark than the Tàrrega station 6.2 km away, with the same number of days above 35 °C. Trepat and Garnatxa shared this weather and its 15 °C daily swing, which keeps the acid a sparkling base needs.

Block figures are the on-site probes at 15-minute resolution: air temperature, and soil temperature and plant-available water at 15, 35 and 50 cm. The probes carry no hygrometer and no rain gauge, so humidity and rainfall come from XEMA station C7 at Tàrrega, 6.2 km away, at half-hourly resolution. Day and night are taken from solar elevation, not from a light sensor. The season runs from 1 April to the day the fruit was picked. Bars show shares and percentages; temperatures sit on one 0–40 °C scale.

Two Trepat harvests, eight days apart

Trepat T1 and Garnatxa were harvested on 18 September; Trepat T2 followed on 26 September. The additional eight days contributed 150 MJ/m² of measured solar energy, seven high-solar days and 60 GDD10. Rain in the final 30 days fell from 21.0 to 5.4 mm.

Observed half-hourly XEMA temperature, humidity, precipitation and global solar irradiance from 1 April to harvest; 99.9% coverage. Irradiance in W/m² is integrated as MJ/m². A high-solar day reaches at least 65% of daily extraterrestrial irradiation. Station observations describe regional exposure at municipality precision: C7 Tàrrega (6.2 km).
