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.

Sustainable wine industry challenge: optimised cork powder us new sustainable fining agent to remove negative volatile phenols

AIM: Cork, the bark of Quercus suber L. is a natural, renewable, sustainable, and biodegradable raw material, representing an abundant and cheap source of raw material. Portugal is the major cork producer (185,000 tons) processing about three-quarters of the world’s cork, generating up to 25 wt % of cork dust as a by-product.

Determination of steviol glycosides in wine by HPLC

The SCL laboratory in Bordeaux is one of the two official control laboratories for wine and wine products in france, under the authority of the ministry of finance and two of its general directorates: the DGCCRF (directorate general for competition, consumer affairs and fraud control) and the DGDDI (directorate general of customs and excise duties). In this capacity, it verifies the regulatory compliance of wines and investigates any possible falsifications or fraud. Steviol glycosides are natural sweeteners that are not authorized as additives in wine.

UNRAVELING THE CHEMICAL MECHANISM OF MND FORMATION IN RED WINE DURING BOTTLE AGING : IDENTIFICATION OF A NEW GLUCOSYLATED HYDROXYKETONE PRO-PRECURSOR

During bottle aging, the development of wine aroma through low and gradual oxygen exposure is often positive in red wines, but can be unfavorable in many cases, resulting in a rapid loss of fresh, fruity flavors. Prematurely aged wines are marked by intense prune and fig aromatic nuances that dominate the desirable bouquet achieved through aging (Pons et al., 2013). This aromatic defect, in part, is caused by the presence of 3-methyl-2,4-nonanedione (MND). MND content was shown to be lower in nonoxidized red wines and higher in oxidized red wines, which systematically exceeds the odor detection threshold (62 ng/L).

Des enjeux individuels à l’action collective

With the Federation of Wine Syndicates of Anjou and the Wine Syndicate of Angevin for direct sale to the Property, the Higher School of Agriculture of Angers was led to carry out, in 1995, a survey of winegrowers in Maine and Loire, with a view to grouping the supply of some of the wines intended for direct sale (Huet, 1995).

Oenological performances of new white grape varieties

The wine industry works to minimize pesticides and adapt to climate change. Breeding programs have developed disease-resistant grape varieties, particularly against downy and powdery mildew, to minimize pesticide applications [1]. However, their enological potential remains underexplored.
