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.

Chemical and microbiological evaluation of Ribeiro wines (NW Spain)

Wine produced under Designation of Origin (DOP) Ribeiro, the oldest DOP in Galicia (NW Spain), are elaborated using local grape cultivars, grown at the valleys of Miño, Avia and Arnoia rivers. The landscape formed by slopes and terraces and the peculiar climate of continental character, softened by the proximity of Atlantic Ocean, make it an area of excellent aptitude for vine cultivation. In addition, small-scale farming and the use of traditional techniques for vineyard management provide a great diversity to Ribeiro wines. This study presents the evaluation of red and white wines (bottled or bulk wines) from DOP Ribeiro, produced between years 2018-2022.

“Silex vitioeno module porte-greffe”: an information system to gather experimental results on grapevine rootstocks

Maintaining stable yields and quality over time is a major challenge for the wine industry. Within the context of climate change, the choice of the rootstock is an important lever for adapting to current and future climatic conditions. Within a vineyard, the choice of the rootstock depends on the environmental conditions, the scion variety and the objectives of production. Many experimental data on the performances of rootstock already exist and can guide our decision-making.
