Chateau de Reignac uses premium grapes from its own vineyards, combining advanced winemaking equipment with traditional techniques to consistently produce high-quality wines that perfectly reflect the unique terroir of its grapes. Currently released wines include Grand Vin de Reignac, Chateau de Reignac, and Chateau de Reignac Blanc, all of which are highly popular.

Grand Vin de Reignac, in particular, gained initial acclaim after a blind tasting event in 2009. The tasting panel comprised 15 professionals from diverse backgrounds, including financial experts, company chairmen, wine merchants, wine journalists, columnists, and sommeliers of the year. Reignac ranked second overall in the tasting, receiving the most enthusiastic discussion and praise from the judges. The most striking aspect was that it was compared to other wines in the blind tasting, including top-tier wines like Haut-Brion, Latour, Lafite, Mouton, and Margaux, as well as Petrus, Ausone, Cheval Blanc, La Mission Haut-Brion, and Angelus, among others. Despite the vast price differences, Reignac only lost to Château Angélus in terms of score. While a single blind tasting may not seem significant, the results were quite interesting for the wine world. The resulting video became a lasting promotional tool for Reignac, and it was even featured in volume 21 of the manga "Drops of God," described as "a powerful groom."
