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.

Spatial variability of temperature is linked to grape composition variability in the Saint-Emilion winegrowing area

Elevated temperature during the grape maturation period is a major threat for grape quality and thus wine quality. Therefore, characterizing the grape composition response to temperature at a larger scale would represent a crucial step towards adaptation to climate change. In response to changes in temperature, various physiological mechanisms regulate grape composition. Primary and secondary metabolisms are both involved in this response, with well-known effects, for example on anthocyanins, and lesser known effects, for example on aromas or aroma precursors. At the field scale or at the regional scale, however, numerous environmental or plant-specific factors intervene to make the effects of temperature difficult to distinguish from overall variability. In this study, it was attempted to overcome this difficulty by selecting well-characterized situations with differing temperatures.
A long-term study of air temperature variability across several Merlot vineyards in the Saint-Emilion and Pomerol wine producing area found significant temperature differences and gradients at various time scales linked to environmental factors. From this study area, a few sites were selected with similar age, soil and training system conditions, and with repeated and contrasted temperature differences during the maturation period. The average temperature difference during the maturation period was about 2°C between cooler and warmer sites, a difference similar to that expected under future climate change scenarios. In close vicinity to the temperature sensors at each site, grape berries were sampled at different times until full maturity during 2019 and 2020. Also, berries from bunches on either side of the row were analyzed separately, allowing an investigation of bunch exposure effect associated with the coupling of berry temperature and solar radiation. Four replicates of pooled berries for each time – site – bunch exposure combination were obtained and analyzed for biochemical composition. Analyses of variance of the biochemical composition data collected at different sampling times reveal significant effects associated with temperature, site, and bunch azimuth. For instance, anthocyanins in grape skins are clearly influenced by temperature and solar radiation exposure, with up to 30% reduction in warmer conditions.

Variations of soil attributes in vineyards influence their reflectance spectra

Knowledge on the reflectance spectrum of soil is potentially useful since it carries information on soil chemical composition that can be used to the planning of agricultural practices. If compared with analytical methods such as conventional chemical analysis, reflectance measurement provides non-destructive, economic, near real-time data. This paper reports results from reflectance measurements performed by spectroradiometry on soils from two vineyards in south Brazil. The vineyards are close to each other, are on different geological formations, but were subjected to the same management. The objective was to detect spectral differences between the two areas, correlating these differences to variations in their chemical composition, to assess the technique’s potential to predict soil attributes from reflectance data.To that end, soil samples were collected from ten selected vine parcels. Chemical analysis yield data on concentration of twenty-one soil attributes, and spectroradiometry was performed on samples. Chemical differences significant to a 95% confidence level between the two studied areas were found for six soil attributes, and the average reflectance spectra were separated by this same level along most of the observed spectral domain. Correlations between soil reflectance and concentrations of soil attributes were looked for, and for ten soil traits it was possible to define wavelength domains were reflectance and concentrations are correlated to confidence levels from 95% to 99%. Partial Least Squares Regression (PLSR) analyses were performed comparing measured and predicted concentrations, and for fifteen out of 21 soil traits we found Pearson correlation coefficients r > 0.8. These preliminary results, which have to be validated, suggest that variations of concentration in the investigated soil attributes induce differences in reflectance that can be detected by spectroradiometry. Applications of these observations include the assessment of the chemical content of soils by spectroradiometry as a fast, low-cost alternative to chemical analytical methods.

Exploring resilience and competitiveness of wine estates in Languedoc-Roussillon in the recent past: a multi-level perspective

The Languedoc-Roussillon wineries are facing a decline in wine yields particularly PGI yields due to many factors. Climate change is just ones, but is expected to increase in the future. There is also structurally a large heterogeneity of yield profiles among terroirs, varieties and strategies. This work investigates the link between yield, competitiveness and resilience to explore how resilient winegrowers have been in the recent past. To this end two approaches have been combined; (i) an accountancy database analysis at estate scale and (ii) municipality level competitiveness analysis. A new resilience indicator that characterizes the capacity of an estate to absorb yield variation is also defined. The FADN database between 2000 and 2018 of ex-Languedoc-Roussillon (France) and other data are used to analyse the current situation and the past evolution of competitiveness and resilience by type of estate (type of farm: PGI and/or PDO & type of commercialization: bulk and/or bottles). The net margin, which defines competitiveness, is not correlated to yield for all types but depends on the type of commercialization and the level of specialisation. The resilience indicator shows that the net margin of estates specialized in PGI is particularly sensitive to yield declines. We also show that price evolutions seem to compensate the effect of yield losses for the majority of types. Municipality scale analysis shows the links between local pedoclimate, yield, commercialization strategies and price. Overlapping a PDO with a PGI does not always increase a municipality’s PGI competitiveness. It is difficult to make links between causes and effects due to the complexity of the wine production system. Production diversification may be a solution. Resorting to the two level of analysis helps resolving the data gap that is necessary to explore the links between yield and economic performance of the wine estates in the long term.

20-Year-Old data set: scion x rootstock x climate, relationships. Effects on phenology and sugar dynamics

Global warming is one of the biggest environmental, social, and economic threats. In the Douro Valley, change to the climate are expected in the coming years, namely an increase in average temperature and a decrease in annual precipitation. Since vine cultivation is extremely vulnerable and influenced by the climate, these changes are likely to have negative effects on the production and quality of wine.
Adaptation is a major challenge facing the viticulture sector where the choice of plant material plays an important role, particularly the rootstock as it is a driver for adaptation with a wide range of effects, the most important being phylloxera, nematode and salt, tolerance to drought and a complex set of interactions in the grafted plant.
In an experimental vineyard, established in the Douro Region in 1997, with four randomized blocs, with five varieties, Touriga Nacional, Tinta Barroca, Touriga Franca and Tinta Roriz, grafted in four rootstocks, Rupestris du Lot, R110, 196-17C, R99 and 1103P, data was collected consecutively over 20 years (2001-2020). Phenological observations were made two to three times a week, following established criteria, to determine the average dates of budbreak, flowering and veraison. During maturation, weekly berry samples were taken to study the dynamics of sugar accumulation, amongst other parameters. Climate data was collected from a weather station located near the vineyard parcel, with data classified through several climatic indices.
The results achieved show a very low coefficient of variations in the average date of the phenophases and an important contribution from the rootstock in the dynamic of the phenology, allowing a delay in the cycle of up to10-12 days for the different combinations. The Principal Component Analysis performed, evaluating trends in the physical-chemical parameters, highlighted the effect of the climate and rootstock on fruit quality by grape varieties.
