A study analyzing the relationship between climatic factors and grape production in Lanzarote between 2002 and 2010, using climate data from the Tinajo station and production figures from the Lanzarote DO Regulatory Council.
Four key climatic factors that influence production volume are identified:
-
Autumn cold accumulation: Buds require cold days to break dormancy. In Lanzarote, the necessary levels are not reached, which can affect budburst.
-
Wind during the previous year's flowering (N-1): Strong wind during flowering can affect floral induction and cause shoots without clusters the following year. This effect was evident in 2010 due to the wind in April 2009.
-
Rainfall volume: Water scarcity can reduce berry size or cause raisin formation, negatively affecting production.
-
Heatwaves close to harvest: Extreme heat can dehydrate grapes, leading to significant volume losses, as occurred in 2009, with a 25–30% reduction.
The analysis shows how specific climatic conditions can directly or indirectly affect vineyard productivity in Lanzarote.
Viticulture and climate change in Lanzarote
The study "Climate and vineyard development; 2016 harvest", prepared by Tomás Mesa on the plots of El Grifo, analyzes how the evolution of temperatures and low winter cold accumulation affect the vine's vegetative cycle in Lanzarote.
Using data collected at the Masdache weather station and the Tinajo central station, phenomena such as heterogeneity in budburst, harvest delay, and the crop reduction observed in 2016 are documented.
This work is part of the research the winery is conducting to understand the impact of climate change on the island's vineyards and to adapt its viticultural practices to an increasingly challenging environment.
