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.

Assessment of alternative sweetening methods for dealcoholized wine

In recent years, there has been an increase in demand for non-alcoholic wine with an ethanol content of less than 0.5% v/v. The dealcoholization process can take place by various methods, such as vacuum distillation or membrane technologies like osmotic distillation. Compared to distillation, membrane systems often require multiple passes or a combination of multiple separation methods. Complete or almost complete removal of ethanol significantly changes the sensory characteristics of wine.

Management of water status in vineyards: meta-analysis of its effects on yield and grape composition

Mediterranean vineyards have been traditionally grown under rainfed conditions, but in recent decades the irrigated area has increased significantly, seeking to minimize the adverse effects of severe water stress on grape quality and yield. Given the large area occupied by vineyards, and the increasing scarcity of water resources, it is necessary to develop strategies for the optimization and efficient use of water to reduce the risk of its overexploitation. The present study aims at valorizing previous knowledge generated in different research projects by means of a meta-analysis of the effects of water status management on vineyard performance.

Detection of spider mite using artificial intelligence in digital viticulture

Aim: Pests have a high impact on yield and grape quality in viticulture. An objective and rapid detection of pests under field conditions is needed. New sensing technologies and artificial intelligence could be used for pests detection in digital viticulture. The aim of this work was to apply computer vision and deep learning techniques for automatic detection of spider mite symptoms in grapevine under field conditions. 

Proposta per un parco produttivo agrovitivinicolo dei “colli piacentini”

Le Dipartimento di Progettazione dell ‘Architettura del Politecnico di Milano et l’Istituto di Viticoltura della Facoltà d’Agraria di Piacenza dell’Università Cattolica del Sacra Cuore, ont elaboré une proposition pour réaliser, dans l’aire de colline de la province de Piacenza, un Parco Produttivo Agrovitivinicolo.

Changes in grape-associated microbiome as a consequence of post-harvest withering

AIM: Grape withering is an oenological post-harvest process used for production of reinforced and sweet wines. Drying can be carried out by keeping the ripe grape in traditional large, well-aired rooms (non-controlled environment) or, more and more often, in a warehouse under controlled conditions of airflow and relative humidity (controlled environment)[1].
