The movie star couple have been working with French winemaker Marc Perrin starting with the 2012 harvest, the website said. The Miraval wine will be on the market in March, and white wines will begin arriving by the end of this summer.
"They ... want to ensure they are making the best Provence wines they can," Perrin told Britain-based Decanter.com. on Wednesday.
"They were present at the blending sessions this year, and are relooking at everything from the installations in the winery - where we have already switched to stainless steel tanks - to reworking the labels across the range of wines," he added.
The back label of the Miraval wine carries the names Jolie-Pitt and Perrin.
Pitt and Jolie began renting Chateau Miraval in Correns, southern France, about four years ago and later bought the property, which has about 148 acres (60 hectares) of vines.
The Miraval wine was formerly called Pink Floyd because the British rock band recorded their 1979 album "The Wall" in a studio on the estate, Decanter.com said.
Pitt last year unveiled a high-end collection of furniture that he helped create with designer Frank Pollaro. He has also worked with architects to create affordable quality housing for victims of Hurricane Katrina in New Orleans.
