The albarizas and the viticultural zoning of Jerez­-Xérès-Sherry and Manzanilla-Sanlúcar de Barrameda registered apellations of origin (Cadiz, Spain)

Abstract

Le terme ”Albariza” (du latin “albus“, blanc) déterminait à l’origine un type particulier du terrain calcaire, mais à présent il sert aussi à définir les sols et la bibliographie géologique actuelle le cite également pour de roches sédimentaires originaires du Neogene Betic.
Dans ce travail, les auteurs montrent la distribution et la géomorphologie des formations “albarizas” et sa participation aux UTB des Appellations d’Origine Contrôlée citées (AOC).
Les horizons du sol, du sous-sol et la roche mère des parcelles viticoles avec le cépage Palomino Fino sont décrits.
Le profil type du sol est ApC avec des variantes (ApC1 C; ApCkC) et avec une profondeur > 4 mètres. Dans le terre fine (Ø < 2 mm) le niveau de matière organique est très faible (< 20 g kg-1 ), les niveaux des carbonates très élevés(≈ 400 g kg-1 ) et la calcaire actif variable (120- 300 g kg-1 ). La CEC est de 20 cmolc kg1 environ et la saturation en bases du 100% (Ca2+ prédominant). La texture est argilo-limoneuse.
Le densité apparente (Da), dans des échantillons inalterés, variable (800-1400 kg M-3) et la porosité totale (Pt) du 58%. La capacité d’aireation (CA) est très élevée dans l’horizon superficiel (30% environ) et faible quoique variable dans le sous-sol (7-17%). L’eau disponible (RU) est de 12-20% et la permeabilité des echantillons saturés lente.
Ces paramètres dont nous venons de parler se complémentent avec des études en lame mince.
L’information ainsi obtenue ajoutée aux doMées climatiques, géomorfologiques, viticoles … est utilisée pour la delimitation des terroirs “albarizas” dans le zonage des AOC citées ci­ dessus.

The term albariza (L. albus, white) was originally applied to a special type of calcareous terrains. Nowadays it is also applied to soils and, in recent geological bibliography, to sedimentary rocks from the Betic Neogene with a particular origin, composition and structure.
In this work, we report the distribution and the geomorphology of the albarizas as well as its presence in diverse UTB in Jerez-Xérès-Sherry and Manzanilla-Sanlucar de Barrameda Registered Appellations of Origin (AOC) zones. The soil cover, subsoil and geological substratum horizons from a number of vineyards have been studied, being the predominant cultivar Palomino Fino.
The soil profile type is ApC with its variations (ApC1C; ApCkC), being high the effective soil depth (>4 m). Organic

matter content in fine earth is very low (<20 g Kg1 ), and total carbonates very high (≈ 400 g Kg-1 ); active lime content is diverse (120-300 g Kg-1 ). The CEC is about 20 cmolc Kg-1 , with a 100% base saturation, mainly due to Ca2+. The predominant soil textural classes are silty clay and silty clay loam.
Bulk density, in unaltered samples, ranges from 850 to 1300 kg m-3 being the average total porosity of 58 %. The air capacity is extremely high in the plough horizon (≈ 20 %). Available soil-water varies from 6 to 21 %. Permeability in saturated samples is slow (0.2-4 cm h-1).
The parameters cited above are completed and explained through the study of thin sections from that material. This information together with other data (climate, geomorphology, vitivinicoles data …) are used for the zoning of the albarizas terrains in Jerez-Xérès-Sherry and Manzanilla-Sanlucar de Barrameda AOC zones.

Characterization of a Sémillon clonal population: exploring genetic diversity, metabolomic profiles, and phenotypic variations

Sémillon is a cultivated grape variety known for contributing to dry and sweet white wine production. However, only seven approved clones have been officially recognized in France[1]. In this study, we aimed to characterize the genetic diversity and metabolomic profiles of a Sémillon clonal population, shedding light on the potential variations within this important grape variety.

Drought tolerance of varieties in semi-arid areas: can the behavior of Tempranillo be improved by varieties of its own lineage?

Tempranillo is the most widely grown red grapevine variety in Spain, currently representing 42% of the total number of red varieties and 21% of the total vineyard area. Due to the economic importance that this variety represents in Spanish viticulture, in some areas where it is traditionally grown, there is a special concern about the viability of the future growing of this variety is being compromised by the climate change effects.

Enological technics to enhance the aromatic qualities of white spirits 

Eugenol has been identified as a quality marker in armagnac white spirits.

The varietal compound of Baco blanc, eugenol has many original properties.
