Evolution of several biochemical compounds during the development of Merlot wine in the vinegrowing “Terroir” of Valea Călugăreasa

Abstract

The qualitative and quantitative distribution of the phenolic compounds in red wines depends on cultivars features, on grapes maturation state, on grapes processing technology including must obtention, as well as on maceration-fermentation method (Margheri, 1981). The last two factors are responsible for the different phenolic composition of the wines produced from the same cultivar. Dealu Mare vineyard offers favourable conditions for a higher capitalization of Cabemet Sauvignon, Pinot noir, Merlot and Fetească neagră cultivars. The red wines having a middle or high content in phenolic compounds and a well-balanced phenolic composition are advisable for being developed in oak barrels (Sommers and Pocock, 1990).

The study which was undertaken at the Research Institute for Viticulture and Enology, Valea Calugareasca, during 1987-1995 was pursuing both the evolution of phenolic composition and wines color, and the influence of the keeping container on the quality of Merlot wine.

Use of ultrasounds to accelerate aging on lees of red wines

Aging on lees (AOL) is a powerful technique to protect varietal aroma and color. Simultaneously, helps to soften tannins and increase and improve wine body and structure. AOL is complementary to barrel aging modulating the wood impact and protecting wine from oxidative conditions.

ANTHOCYANINS EXTRACTION FROM GRAPE POMACE USING EUTECTIC SOLVENTS

Grape pomace is one of the main by-products generated after pressing in winemaking.Emerging methods, such as ultrasound-assisted extraction with eutectic mixtures, have great potential due to their low toxicity, and high biodegradability. Choline chloride (ChCl) was used as a hydrogen bond acceptor and its corresponding hydrogen bond donor (malic acid, citric acid, and glycerol: urea). Components were heated at 80 °C and stirred until a clear liquid was obtained. Distilled water was added (30 % v/v). A solid-liquid ratio of 1 g pomace per 10 ml of eutectic solvent was used.

Reasoning a Terroir policy on the basis of the prospective study of the French wine sector

The prospective study of the French wine sector (Sebillotte et al., 2004) has identified “groups of micro-scenarios” at the end of the analysis of the characteristics of this wine sector.

Effect of the presence of anthocyanins on the interaction between wine phenolic compounds and high molecular weight salivary proteins

As a result of climate change consequences, there is a gap between the times at which the grapes reach the phenolic and the technology maturities.
