Observations made in the departments of Gard and Vaucluse in southern France show a high level of symptoms of downy mildew, a severe fungal disease, on several supposedly fungus-resistant grape varieties, sometimes called piwi grapes.
A new study by INRAE, a French research institute, in collaboration with the universities of Bordeaux and Québec, shows the tolerance of different grapes to drought. Coping with dry weather is a grape characteristic that
Champagne Bollinger’s flagship Vieilles Vignes Françaises (VVF) is made in ever smaller quantities. The grapes come from vines planted franc de pied, a French expression for planted on its own roots. Thus, these vines are
