He married Emma Bernard Le Saint, heiress of the Château Fortia on the southern Rhone. In his new role as a winery owner he was faced with major problems in the département Vaucluse faced. Through the ravages of phylloxera There had been a decline in wine quality. Falsifications with grapes from other areas such as the département Gard were the order of the day. Already in 1923 he defined an area which, according to his analyzes (today one would say: after ecological ) was most suitable for viticulture. His criterion was the wild plants thyme and lavender that grow together here. For this area, he determined the still valid grape varieties, which are most suitable due to soil and climate. He is the founder of the then but in 1935 classified Appellation Châteauneuf-du-Pape,

Therefore, in 1924 he founded a winegrowers' association in Châteauneuf-du-Pape and in 1929 the Union Côtes du Rhône. In 1930 he founded with the restaurateur and writer Maurice E. Sailland alias Curnonsky (1872-1956) the L'Académie du Vin de France modeled on the Académie Française. And with the friendly agriculture professor Joseph Capus (1868-1947) became the forerunner of today in 1935 INAO created its president Boiseaumarié 20 years from 1947 to 1967. Boiseaumarié and Capus are considered to be the founders and pioneers of the French system of origin (see Appellation d'Origine Protégée ). Due to his contribution to the quality of the wine, Pierre Boiseaumarié was named Officer of the Legion of Honor and President of the OIV (Organization Internationale de la Vigne et du Vin).
