Building of a hierarchy of wines based on terroirs: an initiative from the producers of Muscadet

Abstract

The Muscadet area is situated in the southeast of Nantes, close to the Atlantic coast. It constitutes the western extension of the French vineyard “Loire Valley”. The Muscadet is renowned and often spontaneously linked to a white wine.

However it remains misconceived as an ordinary wine, lacking authenticity. Proud of their wines, the Muscadet producers empowered themselves in an ambitious project dating back to the late 1980s. The essential aspects were established on: a fine selection of plots, distinctive vine growing practices and on a lengthening of wine maturation. This approach allowed them to rebuild the hierarchy of appellations, aimed at establishing strong “terroir” identification, which has led to the emergence of “crus communaux”.

The originality of the present study is twofold. First of all, it concerns implementing practical knowledge to identify the most capable fields to produce fine wines and to adapt oenological practices to express the variations of middle. Numerous questions need to be addressed, such as:

– what internal means does a vineyard have and which outside support mechanisms could the winegrowers successfully utilise to complete this step?

– The actors are also central to this study. How could so few innovators change the winegrowing process? And furthermore, how did the producers transform their vision about their natural environment, their knowledge base and their products? Finally, what are the features of these winegrowers, compared with the rest of the vineyard?

– The analysis is based on an intimate knowledge of the vineyard by the authors, coming from various scientific disciplines. Their account is established from a cartographic analysis on several levels. For example, on an enquiry questionnaire that included hundreds of winegrowers, and at meetings with the different actors who wanted to be part of this building process.

Effect of soil particle size on vine water status, leaf ABA content and berry quality in Nebbiolo grapes

The root and shoot abscisic acid (ABA) accumulation in response to water deficit and its relation with stomatal conductance is longtime known in grapevine. ABA-dependent and ABA-independent signalling response to osmotic stress coexist in sessile plants. In grapevine, the signaling role of ABA in response to water stress conditions and its influence on berry quality is critical to manage grapevine acclimation to climate change.

The Tokaj Kereskedőház Ltd. is the only state owned winery in Hungary. The company is integrating grapes for wine production from 1100 hectares of vineyard, which consist of 3500 parcels with average size of 0,3 hectares, owned by about 500 families of the region. The vineyards are unevenly spread in total 27 village of Tokaj region.

Anthocyanin accumulation and extractability during the maturation of the grapes of three varieties

Anthocyanin accumulation and extractability were studied in Tannat, Cabernet Sauvignon and Merlot grapes produced in the south of Uruguay in two consecutive seasons. Typical cultivation situations employed in the region for each variety were considered. A follow-up was carried out, considering 60 plants per vineyard, and the harvest was determined according to the technological indices of maturity. Samples of grapes were taken in duplicate in each vineyard periodically along grape maturation. The basic composition, polyphenolic potential and anthocyanin extractability were determined. Also, half of grapes were frozen and later peeled; skin extractions over 24 hs with a solution of 12% ethanol and pH 3.2 were carried out. The anthocyanin contents of the extracts obtained were determined by HPLC-DAD. The levels of anthocyanins reached the highest values before technological maturity. Anthocyanin extractability had a decrease during grape maturation.
