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.

Ecophysiological performance of Vitis rootstocks under water stress

The use of rootstocks tolerant to soil water deficit is an interesting strategy to cope with limited water availability. Currently, several nurseries are breeding new genotypes, but the physiological basis of its responses under water stress are largely unknown. To this end, an ecophysiological assessment of the conventional 110-Richter (110R) and SO4, and the new M1 and M4 rootstocks was carried out in potted ungrafted plants. During one season, these Vitis genotypes were grown under greenhouse conditions and subjected to two water regimes, well-watered and water deficit. Water potentials of plants under water deficit down to < -1.4 MPa, and net photosynthesis (AN) <5 μmol m-2 s-1 did not cause leaf oxidative stress damage compared to well-watered conditions in any of the genotypes. The antioxidant capacity was sufficient to neutralize the mild oxidative stress suffered. Under both treatments, gravimetric differences in daily water use were observed among genotypes, leading to differences in the biomass of root, shoot and leaf. Under well-watered conditions, SO4 and 110R were the most vigorous and M1 and M4 the least. However, under water stress, SO4 exhibited the greatest reduction in biomass while M4 showed the lowest. Remarkably, under these conditions, SO4 reached the least negative stem water potential (Ψstem), while M1 reduced stomatal conductance (gs) and AN the most. In addition, SO4 and M1 genotypes also showed the highest and lowest hydraulic conductance values, respectively. Our results suggest that there are differences in water use regulation among genotypes, not only attributed to differences in stomatal regulation or intrinsic water use efficiency at the leaf level. Therefore, because no differences in canopy-to-root ratio were achieved, it is hypothesized that xylem vessel anatomical differences may be driving the reported differences among rootstocks performance. Results demonstrate that each Vitis rootstock differs in its ecophysiological responses under water stress.

Soil quality in Beaujolais vineyard. Importance of pedology and cultural practices

A pedological study was carried out from 2009 to 2017 in Beaujolais vineyard, to improve physical and chemical knowledge of soils. It was completed in 2016 and 2017 by the current study, dealing with microbial aspects, in order to build a reference frame for improved advice in soil management. Microbial biomass was measured on representative plots of the six most common soil types identified in Beaujolais and, for each soil type, on plots with different levels of the main impacting parameters: total organic carbon, pH, cation exchange capacity, extractable copper. A total of 59 soil samples were collected. Confirming the results of various trials carried out in Beaujolais over the past 20 years, the results of the present study showed that the soils were still alive, but exhibited a large variability of biological parameters, which appeared dependant on both pedological and anthropic factors. Therefore, a good interpretation of biological parameters and advice for vine growers must rely on a pedologically-based referential with differentiated main driving factors. For example, the control of pH is of primary importance in granitic soils and in no way organic matter addition can improve soil quality if pH is too low. Conversely, in calcareous soils, biological parameters are more directly affected by direct or indirect (cover crops for example) inputs of organic matter. The use of biological parameters, such as microbial biomass, is of great potential value to improve advice on agro-viticultural practices (soil management, fertilization, liming, etc.), basis of a sustainable wine production on fragile soils.

Vineyards and clay minerals: multi-technique analytical approach and correlations with soil properties

Purpose of this research is to quantitatively assess the mineral component of vineyard soils, with particular attention to the mineralogical analysis of clays, which represent an element of high importance in the vineyard culture as well as in general agriculture. An X-ray diffraction (XRD) / thermogravimetric (TG) multi-technique analytical approach was developed, tested on soil samples taken from vineyards around the world. This codified analytical procedure was necessary to obtain precise qualitative and quantitative mineralogical data, globally comparable to distinguish the geopedological identity of the vineyards. Soil samples from vineyards of various locations were analysed, in very different geological conditions. The bulk-rock quantitative phase analysis (QPA) was obtained by the Rietveld method while the detailed composition of the clay-sized fraction was determined by modelling of the oriented X-ray diffraction patterns. The research provided a precise classification of the mineral component of soils, distinguishing the mineral phases of the clays and the so-called mixed-layer clay minerals. We found that the content in mixed layers can be directly correlated with the water retention and the cation exchange capacity ​​of the soil, while the presence of other clayey minerals and phyllosilicates in this research did not affect this CEC parameter, which codes the fertility level of the soils. The study demonstrates that terroir, in particular soils formed in complex or very different geological conditions, can only be effectively interpreted by properly analysing its mineral phases, in particular the mixed-layer clay component. These are characteristic abiotic ecological indicators, which may have specific eco-physiological influences on the plant.

austrianvineyards.com: online viewer of all designations of Austrian wine

To digitally record and present all the origins of Austrian wines in the same perfect and clear way was the motivation for the Austrian Wine Marketing Board (Austrian Wine) to start with the project in 2018. In June 2021 the results were presented to the public in an online viewer showing all the designations of Austrian wine, available at https://austrianvineyards.com in a largely barrier-free manner. The online viewer provides tailored individual maps fitted to the respective zoom level. The smallest unit of wine-origins in Austria is called Ried and is displayed in a plot-specific manner highlighting areas under vine. Information on the Ried include administrative district, winegrowing municipality, cadastral municipality, large collective vineyard site, specific winegrowing region, generic winegrowing region, winegrowing area and, in many cases, an illustrative picture. Complementary data on the size, elevation (minimum-maximum), orientation (in 8 sectors plus flat) and gradient (minimum, maximum, average) are based on the area under vine according to the EU’s Integrated Administration and Control System. Additional information covers climate data. The diagrams are taken from the monthly breakdown of data in the annals of the Central Institute for Meteorology and Geodynamics, Austria provide a display of values for air temperature, precipitation, and sunshine hours for the reference year and the long-term average. Seasonal aggregated data on temperature, precipitation, and sunshine hours complete the display. Short descriptions with emphasis on geology and soil, field name in historical maps, etymology of the denomination, and main planted variety complements the available information for the main designations in the online viewer. These descriptions are compiled by winegrowers, geologists, historians, and journalists. All the information and data can be extracted to a pdf-file. Printed vineyard maps are also available. Missing content regarding wine origins in Styria will be completed in winter 2021/22.

Influence of climatic conditions on grape composition of Tempranillo in La Mancha DO (Spain)

The aim of this work was to analyze the variability in grape composition of the Tempranillo cultivar related to climatic conditions, in La Mancha Designation of Origin. Grape composition (sugar content, total acidity, pH, malic acid, and total and extractable anthocyanins) recorded during ripening, were analysed for the period 2000-2019. The weather conditions at daily time scale, recorded during the same period, were also evaluated. The relationships between grape parameters with climatic variables related to temperature and to water deficits, referring different periods between phenological events along the growing cycle, were evaluated using regression analysis. High variability in grape composition was observed in the period analysed. Total acidity varied between 3.7 and 7.3 gL-1 while malic acid varied between 1.2 and 4 gL-1. The extractable anthocyanins ranged between 526 and 972 mgL-1, and total anthocyanins ranged between 922 and 1388 mgL-1, being the lowest values recorded in the hottest year (2017). Total acidity decreased 0.77 gL-1 for an increase of 100 GDD, while malic acid decrease in 0.42 gL-1 for the same GDD increase, being the period between veraison and harvest the one that seemed to have higher influence on acidity. In addition, it was confirmed that increasing water deficits decreased acidity. Total and extractable anthocyanins increased in about 210 and 105 mgL-1, respectively, with an increase of 100 GDD from veraison to harvest, and the increase in water deficits favour the increase of anthocyanins, both total and extractable anthocyanins. Total and extractable anthocyanins concentration increased in 35 and 22 mgL-1 per an increase of 10 mm in the water deficit. These results can be of interest to understand the potential changes that grapes composition may suffer under future warmer climates.
