Ceramic imprint in wine: influence of hydraulic ratio on ceramic dissolution and wine pH in amphorae systems

Abstract

This interaction is primarily due to an acidic attack on the ceramic by the wine. It results in (1) the dissolution of the ceramic into the wine and the release of a wide variety of elements; and (2) an increase of the wine ph. The extent of these effects depends on the mineralogical and chemical composition of the ceramic, as well as the hydraulic ratio of the ceramic-wine system (the term hydraulic ratio (ρ) defines here the volume of wine over the surface area of the ceramic in contact with the wine). Drawing upon an avrami law describing the dissolution kinetics of the ceramic, we propose and discuss an approach to model the evolution of wine ph as a function of time and ρ ratio. This analysis promises valuable insights into understanding and potentially predicting the dynamic ph changes within the wine as it interacts with ceramic materials over time.

Керамический отпечаток в вине: влияние гидравлического коэффициента на растворение керамики и рн вина в амфорных системах

Это взаимодействие в первую очередь связано с кислотным воздействием вина на керамику. Это приводит к (1) растворению керамики в вине и высвобождению широкого спектра элементов; (2) повышению ph вина. Степень этих эффектов зависит от минералогического и химического состава керамики, а также от гидравлического соотношения системы керамика-вино (термин гидравлическое соотношение (ρ) определяет объем вина по отношению к площади поверхности керамики, находящейся в контакте с вином). Опираясь на закон аврами, описывающий кинетику растворения керамики, мы предлагаем и обсуждаем подход к моделированию эволюции ph вина в зависимости от времени и соотношения ρ. Этот анализ дает ценные сведения для понимания и возможного прогнозирования динамических изменений ph в вине при взаимодействии с керамическими материалами с течением времени.

Empreinte de la céramique dans le vin : influence du rapport hydraulique sur la dissolution de la céramique et le pH du vin dans les systèmes d’amphores

Cette interaction est principalement due à une attaque acide du vin sur la céramique. Elle entraîne (1) la dissolution de la céramique dans le vin et la libération d’une grande variété d’éléments ; (2) une augmentation du ph du vin. L’ampleur de ces effets dépend de la composition minéralogique et chimique de la céramique, ainsi que du rapport hydraulique du système céramique-vin (le terme rapport hydraulique (ρ) définit ici le volume de vin sur la surface de la céramique en contact avec le vin). En s’appuyant sur une loi d’avrami décrivant la cinétique de dissolution de la céramique, nous proposons et discutons une approche permettant de modéliser l’évolution du ph du vin en fonction du temps et du rapport ρ. Cette analyse offre des perspectives intéressantes pour comprendre et éventuellement prédire les changements dynamiques du ph dans le vin lorsqu’il interagit avec les matériaux céramiques au fil du temps.

Enhancing vineyard resilience: evaluating sustainable practices in the Douro demarcated region

In mediterranean agriculture, sustainability and productivity are seriously threatened by climate change and water scarcity. This situation is exacerbated by poor management practices such as excessive use of agrochemicals, overgrazing, and monoculture. The Douro demarcated region (ddr) is an emblematic region, classified world heritage site by UNESCO in 2001. Viticulture is the main agricultural activity in DDR, widely known to produce port wine.

Sensory study of potential kokumi compounds in wine 

Kokumi is a complex sensation perceived as enhanced palatability. Under the influence of kokumi substances, foods/beverages tastes become more flavorful with increased intensity, spread, continuity, richness, harmony, and punch which are the six related characteristics corresponding to the kokumi sensory concept (Yamamoto & Inui-Yamamoto 2023).

Plastic cover film on table grapes from field to cold storage

Plastic film covering is a technique largely used in viticulture to protect table grapes vines from adverse weather conditions and to reduce the negative effects of grapevine fungi disease. Plastic film composition affects solar radiation income inside the covering with effects on sunlight wavelengths in relation to different absorbance and reflectance. The interaction of selected light ranges with vines could influence grape ripening and yield and consequently influence shelf life.

Sustainable geographical indications? Inclusion of sustainability criteria in the Denomination of Origin Campos de Cima da Serra, Brazil

The objective of this study is to assess the potential for integrating sustainability guidelines into Geographical Indications of wine, especially in the case of the Denomination of Origin Campos de Cima da Serra (CCS), Brazil.

Plastid genomics of Vitis vinifera L. for understanding the molecular basis of  grapevine (Vitis vinifera L.) domestication

The precise molecular mechanisms underlying the domestication of grapevine (Vitis vinifera L.) Are still not fully understood. In the recent years, next-generation sequencing (NGS) of plastid genomes has emerged as a powerful and increasingly effective tool for plant phylogenetics and evolution. To uncover the biological profile of the grapevine domestication process comprehensively, an investigation should encompass both the cultivated varieties (V. vinifera subsp. Vinifera) and their wild ancestors V. vinifera subsp. Sylvestris) across all potential sites of their distribution and domestication.
