El viñedo en Lanzarote y el Archipiélago Canario

Abstract

La isla de Lanzarote, primera en ser ocupada en los albores del siglo XV, es la única del archipiélago, junto con Fuerteventura, que no produjo vino. Ocasionalmente hubo algún parral para el consumo de su uva, pero no fue hasta la erupción volcánica de 1730-1736 en que se posibilitó su cultivo.
La dieta mediterránea (pan, aceite, vino, frutas) fue impuesta desde un principio por los ocupantes europeos. Lanzarote producía y exportaba cereales, carne y queso de cabra, mientras que adquiría fuera los vinos, bien andaluces, canarios o madeirenses.
Así siguieron las cosas hasta la erupción volcánica de 1730. Durante casi siete años, la lava y las arenas volcánicas arruinaron las mejores zonas agrícolas de la isla, impidiendo el cultivo de los cereales tradicionales. Ante tanta desgracia se comenzó a observar que ahoyando la tierra, es decir, apartando las arenas volcánicas hasta llegar a la tierra cultivable, podían plantarse árboles frutales, incluso viñas.
En los cuarenta del siglo XVIII se va acelerando el proceso de plantación por los obstáculos legales que se impuso a los aguardientes foráneos, señaladamente catalanes y mallorquines. Ello hizo que los comerciantes tinerfeños a​quella isla dominaba el mercado del vino del archipiélago, además de ser la mayor productora- se interesaran por los incipientes caldos conejeros con la finalidad de convertirlos en aguardiente. A tal fin, instalaron en Arrecife sus destilerías llegando a traer el combustible desde Tenerife, pues esta nueva actividad dejó a los lanzaroteños sin leña para cocinar.
El impulso del viñedo, merced a la demanda tinerfeña aceleró su plantación, que resultaba muy fatigosa pues obligaba a ahoyar las arenas (lo que solucionaba en parte la escasez de agua) y a proteger la planta de los vientos, bien con el hoyo de arena si resultaba lo suficiente profundo, bien mediante la construcción de unas pequeñas paredes de piedra seca, obtenidas picando las rocas volcánicas.
George Glas, comerciante británico, profundo conocedor de la sociedad canaria del segundo tercio del siglo XVIII, ilustrado y llevado a prisión por la Inquisición, mercader de vinos, viajero incansable y que visitó varias veces Lanzarote, nos da cuenta del incipiente comienzo de la viña en nuestra isla. Según él, en la década de 1750 o inicios de 1760 se producía cierta cantidad de vino que casi en su totalidad se exportaba a Tenerife, una vez destilado.
En 1749, el Cabildo lanzaroteño ya adopta un acuerdo “sobre la preferencia de los vinos de esta isla y compra de pipas de las que vienen de fuera”.
En 1776, aparece una obra de autor desconocido, titulada “El Compendio”, que nos da una idea pormenorizada del estado de la agricultura en la isla, cuarenta años después de la erupción del Timanfaya. Destaca que el viñedo se multiplica y que el vino se destinaba en su mayor parte para la elaboración de aguardientes que los tinerfeños realizaban en Arrecife, impulsando su desarrollo en detrimento de la Villa de Teguise, a la que acabó por arrebatar la capitalidad de la isla.
A mediados del XVIII, los malvasías canarios estaban casi desaparecidos, porque se elaboraban nuevos vinos tipo madeira (y que pasaban por tales en el mercado internacional), muy alcohólicos y con bastante color, que se obtenía utilizando parte de uva negra. En Lanzarote primaban las listanes blancas, como en el resto del archipiélago.
En el comienzo del siglo XIX, el vino lanzaroteño se consume cada vez más como vino, disminuyendo por tanto la importancia de los destilados. Este proceso se ve acelerado por la decadencia de los vinos canarios a partir de 1818, que llevó en 1853 a su casi exterminio, merced a unos ataques de oidio mal combatidos. La importancia de la vinificación en Lanzarote desde los comienzos del XIX, hizo que se sustituyeran buena parte de los Listanes por cepas de Malvasía, algo menos productiva pero de mayor calidad. En esta época la crisis afectó a los vinos comunes, con lo cual hasta finales del XIX, consecuencia de la filoxera en Francia, no se produce una recuperación de los vinos canarios.
En la exposición vitícola nacional de 1877, celebrada en Madrid como consecuencia del boom vitivinícola que se produjo como consecuencia del ataque de filoxera en Francia, se elaboró un informe sobre plantaciones, varietales, tipos de vino, etc.
De Lanzarote destaca como variedad la Malvasía, plantada en la isla a lo largo del XIX, probablemente de Sitges, varietal y vino fuertemente cotizados en la península desde comienzos de dicho siglo. En los comienzos de la viña lanzaroteña se plantaron los listanes, más productivos, ya que se trataba de elaborar aguardientes, aunque posteriormente fue la Malvasía la que se plantó de modo mayoritario cuando se trataba de exportar vinos a las islas mayores.
El siglo XX puede resumirse en lo ocurrido en los últimos años. En los años 60-70 se produce un abandono de gran parte del viñedo, principalmente de grandes propietarios debido al inicio del ciclo turístico. Esto supone también el cierre de muchas bodegas.
En la década de los 80, se inicia el cambio de los métodos de vinificación, introduciendo nuevas tecnologías que acercan la producción a los gustos del consumidor.

Modelling vine water stress during a critical period and potential yield reduction rate in European wine regions: a retrospective analysis

Most European vineyards are managed under rainfed conditions, where seasonal water deficit has become increasingly important. The flowering-veraison phenophase represents an important period for vine response to water stress, which is seldomly thoroughly evaluated. Therefore, we aim to quantify the flowering-veraison water stress levels using Crop Water Stress Indicator (CWSI) over 1986–2015 for important European wine regions, and to assess the respective potential Yield Lose Rate (YLR). Additionally, we also investigate whether an advanced flowering-veraison phase may help alleviating the water stress with improved yield. A process-based grapevine model STICS is employed, which has been extensively calibrated for flowering and veraison stages using observed data at 38 locations with 10 different grapevine varieties. Subsequently, the model is being implemented at the regional level, considering site-specific calibration results and gridded climate and soil datasets. The findings suggest wine regions with stronger flowering-veraison CWSI tend to have higher potential YLR. However, contrasting patterns are found between wine regions in France-Germany-Luxembourg and Italy-Portugal-Spain. The former tends to have slight-to-moderate drought conditions (CWSI<0.5) and a negligible-to-moderate YLR (<30%), whereas the latter possesses severe-to-extreme CWSI (>0.5) and substantial YLR (>40%). Wine regions prone to a high drought risk (CWSI>0.75) are also identified, which are concentrated in southern Mediterranean Europe. An advanced flowering-veraison phase may have benefited from cooler temperatures and a higher fraction of spring precipitation in wine regions of Italy-Portugal-Spain, resulting in alleviated CWSI and moderate reductions of YLR. For those of France-Germany-Luxembourg, this can have reduced flowering-veraison precipitation, but prevalent alleviations of YLR are also found, possibly because of shifted phase towards a cooler growing season with reduced evaporative demands. Overall, such a retrospective analysis might provide new insights towards better management of seasonal water deficit for conventionally vulnerable Mediterranean wine regions, but also for relatively cooler and wetter Central European regions.

Mobile device to induce heat-stress on grapevine berries

Studying heat stress response of grapevine berries in the field often relies on weather conditions during the growing season. We constructed a mobile heating device, able to induce controlled heat stress on grapes in vineyards. The heater consisted of six 150 W infrared lamps mounted in a profile frame. Heating power of the lamps could be controlled individually by a control unit consisting of a single board computer and six temperature sensors to reach a pre-set temperature. The heat energy applied to individual berries within a cluster decreases by the squared distance to the heat source, enabling the establishment of temperature profiles within individual clusters. These profiles can be measured by infrared thermography once a steady state has been reached. Radiant flux density received by a berry depending on the distance was calculated based on a view factor and measured lamp surface temperature and resulted to 665 Wm-2 at 7cm. Infrared thermography of the fruit surface was in good agreement with measurements conducted with a thermocouple inserted at epidermis level. In combination with infrared thermography, the presented device offers possibilities for a wide range of applications like phenotyping for heat tolerance in the field to proceed in the understanding of the complex response of plants to heat stress. Sunburn necrosis symptoms were artificially induced with the aid of the device for cv. Bacchus and cv. Sylvaner in the 2020 and 2021 growing season. Threshold temperatures for sunburn induction (LT5030min) were derived from temperature data of single berries and visual sunburn assessment, applying logistic regression. A comparison of threshold temperatures for the occurrence of sunburn necrosis confirmed the higher susceptibility of cv. Bacchus. The lower susceptibility of cv. Sylvaner did not seem to be related to its phenolic composition, rendering a thermoprotective role of berry phenolic compounds unlikely.

δ13C : A still underused indicator in precision viticulture  

The first demonstration of the interest of carbon isotope composition of sugars in grapevine, as an integrated indicator of vineyard water status, dates back to 2000 (Gaudillère et al., 1999; Van Leeuwen et al., 2001). Thanks to the isotopic discrimination of Carbon that takes place during plant photosynthesis, under hydric stress conditions, it is possible to accurately estimate the photosynthetic activity. Ever since, δ13C has been widely applied with success to zonation, terroir studies and vine physiology research, but is still not widely used by viticulturists. This is quite astonishing by considering the impact of global warming on viticulture and the need to improve water management, that would justify a widespread use of δ13C.
The lack of private laboratories proposing the analysis, the cost of the technology, as well as the long analytical delays, have been detrimental to its development. Some laboratories tried to overcome the analytical difficulties of isotopic analysis by using fourier transformed infrared spectroscopy, as a fast and cheap alternative to the official OIV method (IRMS). These claimed FTIR models have never been published or peer reviewed and cannot be considered robust. In this work, thanks to the recent acquisition of IRMS technology, new modern and robust applications of δ13C for viticulture are proposed. This includes the use of the analysis to make parcel separations at harvesting, the possibility to increase the precision of hydric stress cartography and the potential cost reduction when compared with Scholander pressure bomb analysis.

Climate and the evolving mix of grape varieties in Australia’s wine regions

The purpose of this study is to examine the changing mix of winegrape varieties in Australia so as to address the question: In the light of key climate indicators and predictions of further climate change, how appropriate are the grape varieties currently planted in Australia’s wine regions? To achieve this, regions are classified into zones according to each region’s climate variables, particularly average growing season temperature (GST), leaving aside within-region variations in climates. Five different climatic classifications are reported. Using projections of GSTs for the mid- and late 21st century, the extent to which each region is projected to move from its current zone classification to a warmer one is reported. Also shown is the changing proportion of each of 21 key varieties grown in a GST zone considered to be optimal for premium winegrape production. Together these indicators strengthen earlier suggestions that the mix of varieties may be currently less than ideal in many Australian wine regions, and would become even less so in coming decades if that mix was not altered in the anticipation of climate change. That is, grape varieties in many (especially the warmest) regions will have to keep changing, or wineries will have to seek fruit from higher latitudes or elevations if they wish to retain their current mix of varieties and wine styles.
