Influence of edapho-climatic factors on grape quality in Conca de Barberà vineyards (Catalonia, Spain)

Abstract

Soil and climate of 3 vineyards have been characterised in order to determine their influence on grape quality. These vineyards are located in Conca de Barberà (Catalonia, NE Spain) and belong to Cabernet sauvignon and Grenache noir cultivars. All 3 plots are very close, so only interannual climatic data of the nearest meteorological station have been considered. Different climatic indexes have been calculated from climatic data. The studied vineyard soils present very different textural classes and rock fragment contents, causing very distinct soil water regimes. Besides determining chemical and physical properties of soils, the soil water availability has been characterised using capacitance sensors at different depths for the period from 2003 to 2005. Data of quality of grapes were available. Statistical techniques, concretely Principal Component Analysis and Multiple Regression Analysis, have been used to relate edapho-climatic factors to grape quality. The results show that edapho-climatic data have a high power of estimation on grape quality (generally, R2 higher than 0.75). Climate appeared to be the most influencing factor, followed by water availability. Soil had also influence on grape yield and some must data.

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
