Agronomical assessment of a vine « terroir » map: first results in the « AOC » Minervois region

Abstract

Minervois is a vine region where the first detailed soil map was begun 30 years ago. In 2003, a new map was drawn plotting the soil-landscape associations. This map distinguishes 8 large soil units based on geology. The widest (called « marnes ») is the most complex : it is made of 57 sub-units, which leads to a high variability of the vine behaviour on this unit. We proposed a way to simplify that very complex soil information in order to understand the relationship between vines characteristics and the map sub-units of soil. The 57 first sub-units were turned into 5 new ones. Water constraint and agronomical data were examined for 2 vine cultivars on 47 vine plots among the « marnes » unit and compared to 3 of our simplified sub-units (87% of the total area of the « marnes » unit). Shoot elongation and carbon discrimination were used for estimating water regime during summer. The soil-plant water regime is revealed to be the main factor classifying the 3 sub-units : we show good relationship between grapes and vines characteristics and the new sub-units.

Significance of factors making Riesling an iconic grape variety

Riesling is the iconic grape variety of Germany and accounts for 23% of the German viticulture acreage, which comprises 45% of the worldwide Riesling plantings. Riesling wines offer a wide array of styles from crisp sparkling wines to highly concentrated and sweet Trockenbeerenauslese or Icewines. However, its thin berry skin makes Riesling more vulnerable to detrimental environmental threats than other white wine varieties.

Winemaking techniques and wine tasting methods at the end of the Middle Ages

Les pratiques de vinification et de dégustation du vin sont souvent perçues, à travers un discours marketing très puissant, sous l’angle d’une tradition millénaire qui perdure depuis le Moyen Âge. En Bourgogne, il est courant de rattacher les racines de ces pratiques à l’activité des institutions ecclésiastiques qui possédaient d
