A general phenological model for characterising grape vine flowering and véraison


The timing of phenology is critical if grape quality potential is to be optimized. Phenological process based models are used to predict phenology. In this study, three different models were tested to predict flowering and veraison of grapevine (Vitis vinifera L.) using a new extensive phenological database. The Spring Warming model was found optimal in its trade-off between parsimony (number of parameters) and efficiency. The optimal parameter combination found for this model to calculate the degree-days was 0°C for the base temperature and the 60th day of the year for the starting day of accumulation (northern hemisphere). This model was validated at the varietal level, performed better than the classic Spring Warming model with Tb of 10 °C and t0 of 1st January (northern hemisphere) and remains easy to use.

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
