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.

Effect of multi-level and multi-scale spectral data source on vineyard state assessment

Currently, the main goal of agriculture is to promote the resilience of agricultural systems in a sustainable way through the improvement of use efficiency of farm resources, increasing crop yield and quality under climate change conditions. This last is expected to drastically modify plant growth, with possible negative effects, especially in arid and semi-arid regions of Europe on the viticultural sector. In this context, the monitoring of spatial behavior of grapevine during the growing season represents an opportunity to improve the plant management, winegrowers’ incomes, and to preserve the environmental health, but it has additional costs for the farmer. Nowadays, UAS equipped with a VIS-NIR multispectral camera (blue, green, red, red-edge, and NIR) represents a good and relatively cheap solution to assess plant status spatial information (by means of a limited set of spectral vegetation indices), representing important support in precision agriculture management during the growing season. While differences between UAS-based multispectral imagery and point-based spectroscopy are well discussed in the literature, their impact on plant status estimation by vegetation indices is not completely investigated in depth. The aim of this study was to assess the performance level of UAS-based multispectral (5 bands across 450-800nm spectral region with a spatial resolution of 5cm) imagery, reconstructed high-resolution satellite (Sentinel-2A) multispectral imagery (13 bands across 400-2500 nm with spatial resolution of <2 m) through Convolutional Neural Network (CNN) approach, and point-based field spectroscopy (collecting 600 wavelengths across 400-1000 nm spectral region with a surface footprint of 1-2 cm) in a plant status estimation application, and then, using Bayesian regularization artificial neural network for leaf chlorophyll content (LCC) and plant water status (LWP) prediction. The test site is a Greco vineyard of southern Italy, where detailed and precise records on soil and atmosphere systems, in-vivo plant monitoring of eco-physiological parameters have been conducted.

Water deficit differentially impacts the performances and the accumulation of grape metabolites of new varieties tolerant to fungi

The use of resistant varieties is a long-term but promising solution to reduce chemical input in viticulture. Several important breeding programs in Europe and abroad are now releasing a range of new hybrids performing well regarding fungi susceptibility and producing good quality wines. Unfortunately, insufficient attention is paid by the breeders to the adaptation of these varieties to climatic changes, notably to the increased climatic demand and water deficit (WD). Thus, prior to the adoption of such varieties by the wine industry in Mediterranean regions, there is a need to consider their suitability to WD. This study aimed to characterize the different drought-strategies adopted by 6 new resistant varieties selected by INRAE in comparison to Syrah. To allow the assessment of long-term impacts of WD, field-grown vines were exposed to contrasted WD from 2018 to 2021 under a semi-arid Mediterranean climate. A gradient of WD was applied in the field and controlled through plant measurements at the single plant level. Grape development was non-destructively monitored to determine the arrest of berry phloem unloading. The impacts of WD on berry composition, including water, primary metabolites (sugars, organic acids), secondary metabolites (anthocyanins, thiols precursors) and main cations contents, were assessed at this specific stage. Results showed different varietal responses during the year and inter-annual acclimation in terms of plant water use efficiency, biomass accumulation, as well as yield components and berry composition. WD differentially reduced the accumulation of primary metabolites at plant and berry levels, but it little changed their concentrations in the fruits at the ripe stage. Moreover, WD differentially impacted the accumulation of secondary metabolites and major cations between the varieties. In the talk, we’ll present the main results regarding the WD impacts on fruit metabolites and enlarge the reflection about the practical assessment of the grapevine acclimation to WD.

Permanent cover cropping with reduced tillage increased resiliency of wine grape vineyards to climate change

Majority of California’s vineyards rely on supplemental irrigation to overcome abiotic stressors. In the context of climate change, increases in growing season temperatures and crop evapotranspiration pose a risk to adaptation of viticulture to climate change. Vineyard cover crops may mitigate soil erosion and preserve water resources; but there is a lack of information on how they contribute to vineyard resiliency under tillage systems. The aim of this study was to identify the optimum combination of cover crop sand tillage without adversely affecting productivity while preserving plant water status. Two experiments in two contrasting climatic regions were conducted with two cover crops, including a permanent short stature grass (P. bulbosa hybrid), barley (Hordeum spp), and resident vegetation under till vs. no-till systems in a Ruby Cabernet (V. vinifera spp.) (Fresno) and a Cabernet Sauvingon (Napa) vineyard. Results indicated that permanent grass under no-till preserved plant available water until E-L stage 17. Consequently, net carbon assimilation of the permanent grass under no-till system was enhanced compared to those with barley and resident vegetation. On the other hand, the barley under no-till system reduced grapevine net carbon assimilation during berry ripening that led to lower content of nonstructural carbohydrates in shoots at dormancy. Components of yield and berry composition including flavonoid profile at either site were not adversely affected by factors studied. Switching to a permanent cover crop under a no-till system also provided a 9% and 3% benefit in cultural practices costs in Fresno and Napa, respectively. The results of this work provides fundamental information to growers in preserving resiliency of vineyard systems in hot and warm climate regions under context of climate change.

Modulation of berry composition by different vineyard management practices

High concentration of sugars in grapes and alcohol in wines is one of the consequences of climate change on viticulture production in several wine-growing regions. In order to investigate the possibilities of adaptation of vineyard management practices aimed to reduce the accumulation of sugar during the maturation phase without reducing the accumulation of anthocyanins in grapes, a study with severe shoot trimming, shoot thinning, cluster thinning and date of harvest was conducted on Merlot variety in Istria region (Croatia), under the Mediterranean climate. Four factors which may affect grape maturation and its composition at harvest were investigated in a two-years experiment; severe shoot trimming applied at veraison when >80% of berries changed colour (in comparison to untreated control), shoot thinning (0 and 30%), cluster thinning (0 and 30%), and the date of harvest (early and standard harvest dates). Shoot thinning had no significant impact on berry composition, despite the obtained reduction in yield per vine. Lower Brix in grapes were obtained with earlier harvest date and if no cluster thinning was applied, although at the same time a reduction in the concentration of anthocyanins in berries was observed in these treatments. On the other hand, if severe shoot trimming was applied when >80% of berries changed colour, a reduction of Brix was obtained without a negative impact on berry anthocyanins concentration. We conclude that in cases when undesirably high sugar concentrations at harvest are expected, severe shoot trimming at 80% veraison may effectively be used in order to obtain moderate sugar concentration in berries together with the adequate phenolic composition.

Spatiotemporal patterns of chemical attributes in Vitis vinifera L. cv. Cabernet Sauvignon vineyards in Central California

Spatial variability of vine productivity in winegrapes is important to characterise as both yield and quality are relevant for the production of different wine styles and products. The objectives were to understand how patterns of variability of Cabernet Sauvignon fruit composition changed over time and space, how these patterns could be characterised with indirect measurements, and how spatial patterns of the variation in fruit compositional attributes can aid in improving management. Prior to the 2017 vintage, 125 data vines were distributed across each of four vineyards in the Lodi American Viticultural Area (AVA) of California. Each data vine was sampled at commercial harvest in 2017, 2018, and 2019. Yield components and fruit composition were measured at harvest for each data vine, and maps of yield and fruit composition were produced for eight ‘objective measures of fruit quality’: total anthocyanins, polymeric tannins, quercetin glycosides, malic acid, yeast assimilable nitrogen, β-damascenone, C6 alcohols and aldehydes, and 3-isobutyl-2-methoxypyrazine. Patterns of variation in anthocyanins and phenolic compounds were found to be most stable over time. Given this relative stability, management decisions focused on fruit quality could be based on zonal descriptions of anthocyanins or phenolics to increase profitability in some vineyards. In each vineyard, dormant season pruning weights and soil cores were collected at each location, elevation and soil apparent electrical conductivity surveys were completed, and remotely sensed imagery was captured by fixed wing aircraft and two satellite platforms at major phenological stages. The data collected were used to develop relationships among biophysical data, soil, imagery, and fruit composition. The standardised and aggregated samples from four vineyards over three seasons were included in the estimation of ‘common variograms’ to assess how this technique could aid growers in producing geostatistically rigorous maps of fruit composition variability without cumbersome, single season sampling efforts.
