Jerez Sherry Vineyards — Live Satellite Health Report

About this region

Jerez de la Frontera, in Andalusia, is the birthplace of sherry — the fortified wine made from Palomino Fino and aged in a solera system under a layer of flor yeast. The chalky albariza soils (white, moisture-retentive marl) are the region’s defining terroir: they reflect sunlight onto the vines, moderating temperature, and store winter rainfall for the long, rainless growing season. Without the albariza’s sponge-like properties, viticulture in this climate would be nearly impossible.

Climate & growing cycle

The climate is hot Mediterranean with very dry summers and mild winters. Palomino Fino buds in March, flowers in May, and harvests in early September — one of the earliest harvests in Europe. The albariza acts as a soil reservoir, holding winter rain that the vines draw on through the dry season. The canopy is kept open and the vines are often bush-trained (en vaso), producing modest leaf area that matches the limited water supply.

Satellite monitoring insights

NDVI peaks at 0.3–0.45 on Jerez vines — reflecting the dry, open viticulture of southern Spain. Water stress (NDMI) is the region’s defining management challenge: the albariza can store enough winter rain for a normal season, but a drought winter followed by a hot summer can deplete the reserve before véraison, and satellite monitoring picks this up weeks before the vines show visible stress. The bright white albariza soil creates unusually high background reflectance, so SAVI is essential for accurate canopy vigour readings.

Key metrics

Index	Peak range	Albariza-specific signal
NDVI	0.3–0.45	Open, bush-trained canopy
NDMI	−0.2 to 0.1	Albariza moisture reserve status
SAVI	0.2–0.35	Corrects for the bright white soil background
