Nitrogen status of vines influences aged wines aromas. Examples of aged Champagne reserve wines and red Bordeaux wines

Abstract

The sensory definition of the aging bouquet of red Bordeaux wines has been shown to be structured around seven main aromatic nuances: “undergrowth”, “spicy” “truffle”, “fresh red- and black-berry fruits”, “liquorice”, “mint”, and “toasted” (1). Some of these descriptors are also used to describe the aromatic notes of old Champagnes (2) suggesting common volatile compounds between these two types of wine.

The wine quality is closely related to its aromatic expression, influenced by the grape variety, viticultural management techniques and environmental factors, such as soil and climate (3). It has been shown that the soil influences the taste of wines and the typicity of organoleptic expression. This is largely mediated by the availability of water and nitrogen (4). The climate effect is mediated by air temperature and water balance (5).

The volatile compounds developed during wine aging and involved in the expression of the bouquet may be affected by vine water and nitrogen status (6). High nitrogen status in vines favors high nitrogen levels in both grape berries and wine. Thus, compounds such as tabanone, DMS, esters and aromatic heterocycles were measured in aged Bordeaux and Champagne reserve wines. Their concentrations were correlated to the water and nitrogen status in vine (evaluated during the season for the year production with Bordeaux vine) and the amino acids concentration in wines for Champagne reserve wine.

For both wines types, it has been revealed that the vine nitrogen status and the wine nitrogen composition have an important role on DMS, ester and aromatic heterocycles formation. Furthermore, a correlation between tabanones concentrations and the vine water status was observed.

Data collection for both red Bordeaux and Champagne reserve wines, which bouquet is well disguised, highlighted that nitrogen is involved in the various stages, common and/or different for both wine type, from vine formation to aged wine.

Etude des effets millésime, situation et sol à partir d’un observatoire du Gamay en beaujolais

Des expérimentations sur Gamay ont été réalisées en Beaujolais de 2000 à 2006 sur 10 parcelles d’AOC différentes. De nombreuses mesures ont été effectuées à différents stades (vigne, baies récoltées, vinification et bouteille avec ou sans vieillissement). Ces mesures sont également de natures différentes (données phénologiques, analytiques, dégustation). Des analyses de la composition des sols sont également disponibles.
