Interaction Between Armenian Clay-based Ceramic and Model Wine

Abstract

Clay-based ceramic vessels (jars, pyhtoi, etc.) for wine fermentation and aging processes have been used in several cultures for millennia. This know-how still in practice in several countries of the Armenian highland is gaining worldwide in curiosity, popularity, and interest. Ceramic pots are famous among traditional winemakers for their benefits such as temperature regulation, natural cooling system, favorable oxygen exchange, and impact on pH, which are different from those of stainless steel, wood barrels, or concrete.

Despite a 5000-years-old history of the use of clay-ceramic vessels (amongst other in Armenia), there is only few scientific regard on the impact on wine quality. To approach this subject, it is necessary to recourse to many analytical techniques and we only report some results obtained by ICP-AES and proton NMR relaxometry on a model wine.

ICP-AES is used to identify the migration of elements from the ceramic to the model wine. The results of the elemental analysis of the model wine in contact with ceramics over time showed that a large number of elements were transferred from the ceramic to the model wine with different migration behaviors. The noticeable amount of migrating iron attracted attention.

NMR relaxometry is used to follow in situ, the migration of paramagnetic elements (like iron), reduction of iron, but also the consumption of dioxygen in the model wine in contact with the ceramic.

It is also shown that coated ceramic (e.g .with bee wax; a traditional Armenian method) can drastically limit chemical exchange.

DOES LIGNIN AN ACCEPTABLE MARKER OF GRAPESEED MATURATION AND QUALITY?

Usually the winemaker consider polyphenols from the grape berry as an actor of the wine quality. There are frequently consider as a marker of grape maturity. It is commonly known that winemaker consider tannins and anthocyanins as main polyphenol actors for winemaking practices and wine quality. Here we will focus on the characterisation of lignins in grape seeds. Previous studies suggest that the seed is lignified [1], which could explain the change in colour of the seed when it reaches maturity and thus provide a reliable indicator for describing the maturity stage in the seed.

Text mining of wine reviews to investigate quality markers of ‘Nebbiolo’ wines from Valtellina

In Valtellina zone (north Italy), the winemaking of ‘Nebbiolo’ grapes leads to the production of two main wine types: classic red wines from fresh grapes, usually classified as Valtellina Superiore DOCG (mandatory oak aging) or Rosso di Valtellina DOC, and the Sforzato di Valtellina DOCG, which is produced using withered grapes according to traditional product specification and subjected to mandatory oak aging process. The withering process influences grape chemical composition and, in turn, the wine sensory profile, which is strongly linked to the wine quality and typicity perceived by consumers.

Health space in vine spa in the world

This elaboration presents vine spa has precious contribution of social development health and well being in culture of wine regions. The majority of the vine-spas in the world draw raw materials from the vineyard; both for cosmetics treatments and for dishes in their restaurants. Vitis vinifera vine provides fresh grapes for dishes and massages, seeds and oil from the seeds, as well as the leaves, and its extracts, and above all the wine.

Genetic determinism of grapevine development stages as a tool for the adaptation to climate change

A major goal of modern grapevine (Vitis vinifera L.) breeding programs is the introgression of resistance genes along with desirable traits for better adaptation to climate change. Developmental stages have an impact on yield components and berry composition and are expected to shift towards earlier dates in the future. We investigated the genetic determinism of phenological stages in the progeny of a cross between two grapevine hybrids, each carrying several quantitative trait loci (QTL) for downy mildew and powdery mildew resistance.
