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.

French wine sector facing climate change (part. 2) : the implementation of the national strategy

This summary follows this made by Hervé Hannin et al. Entitled “French wine sector facing climate change (part. 1) : a national strategy built on a foresight and participatory approach “. The french wine sector has taken a collective approach to the issue of climate change, and has officially submitted its strategy to the minister of agriculture in 2021. This industry policy is the result of multidisciplinary work carried out through the “laccave” project (metaprogramme accaf, inrae) and its prospective study designed to anticipate climate change in the french wine industry (aigrain p. Et al., 2016). French wine professionals decided to structure a strategy to deal with climate change du in particular to the presentation made at the 2016 OIV congress in Brazil.
