The domaine is 9.4 hectares (under plantation, there is 12 hectares total), 7 of which are located in the great terroir of Brézé. A little more than half of the surface is planted to Chenin with the remainder planted to Cabernet Franc. Age of vines varies between 4 and 80 years old, with a hefty proportion of old vines. In 2000, Romain converted the vineyards to organic management and in 2003 he began the process towards the AB organic certification, obtaining it in 2007. In only a few years, Domaine Guiberteau has become one of the most sought after domaines in Saumur, their wines already stringently allocated and found in the best restaurants in France.
