Le Prince wine is made from old Cabernet Franc vines aged around forty years. These vines benefit from a remarkable terroir: they are rooted in a clay-limestone soil from the Upper Turonian period, on a mother rock of yellow tufa, perfectly representative of the Saumur-Champigny appellation.
The Rocheville vineyard has been under sustainable viticulture since 2005, the Prince’s first vintage. In 2011, the estate obtained Terra Vitis certification and it converted to Organic Agriculture in 2016.
In the vineyards, this means maintaining natural grass cover, constant attention to the preservation of the biodiversity, mechanical tilling of the soil and plant care designed to limit the production of bunches of grapes in order to increase juice concentration (such as short pruning).
The objective is therefore to produce quality wines but also to respect nature and your health for a multiplied pleasure.
The vines are harvested by hand at optimal maturity. With a yield of 40 hl/ha, the Prince is well below the average for the appellation.
