As opposed to his ancestors (high-ranking officers in the French army and industrialists who only paid serious attention to the estate once they had retired) Baron Louis-Gabriel de Jerphanion decided to call a halt to his career in aeronautical and petroleum engineering in 1980 to look after the family estates.

These consist of Château Moncets in Lalande de Pomerol (the wine is also sold by Bordeaux merchants under the name of Château Gardour) and Château La Bastidette (Montagne Saint-Emilion).
Since he took over the estate, Louis-Gabriel de Jerphanion has increased the area under vine by a third, while maintaining quality as more of a priority than ever. His wine is produced with the greatest of care, in the most traditional way possible: ageing in oak barrels, racking with a bellows, fining with egg whites, light filtration, etc.
