Maison la Berthaude is a private-label Châteauneuf-du-Pape produced exclusively by Domaine Roger Perrin in the Rhône Valley, which is wholly owned by Roger Perrin. The wines draw on centenary vines planted in the early 1900s. Winemaking is led by second-generation winemaker Véronique Perrin-Rolin, with her son Xavier Rolin also credited on recent releases. The available information does not specify vineyard area, production volume, sustainability certification, or particular farming practices.
