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.

Origin of unpleasant smelling sulphur compounds during wine fermentation

The wine sector is undergoing considerable transformation, particularly as a result of climate change and increasing consumer expectations for quality products, in a globalised and increasingly competitive market.

Vineyard management practices to reduce sugar content on ‘Monastrell’ grapes

Climate change is resulting in more dry and hot summers, accelerating grape ripening and increasing berry sugars concentration. This results in wines with a higher alcohol content, which has a negative impact on wine quality, as well as, on consumer health. Agronomic practices that minimize these effects on berry composition and, consequently, on wine quality must be defined. In this work, different management practices have been assessed on rainfed ‘Monastrell’ grapevines in Jumilla (Murcia, Spain) from 2021 to 2023 vintages. Mulching, shading, application of kaolin and different types of pruning were evaluated, among others field adaptation practices.

Effect of ozone application for low-input postharvest dehydration of wine grapes

The postharvest dehydration of grapes is a traditional practice to obtain wines with unique traits (e.g., sweet, dry/reinforced).

Exploring changes in browning kinetics, color, and antioxidants due to dealcoholization of wine

The global consumer demand for low or non-alcoholic wine is growing steadily in recent years, driven by health concerns, religious beliefs, and personal taste preferences etc.. Consequently, the removal of alcohol from wine can significantly alter its chemical and sensory properties, including color, aroma, and taste, which make a significant challenge for consumer to accept these products. Ethanol plays a crucial role in various chemical reactions and interactions that contribute to the development of wine’s characteristics.
