Château Mourgues du Grès is one of the pioneers of the Costières de Nîmes and is recognized as one of the very best estates in the region in the Wine Advocate and in the French magazines Revue de Vin de France, Guide Hachette, and Gilbert et Gaillard. Mourgues du Grès is run by Anne and François Collard. François’s father was the first owner and he made wine, but mostly sold grapes in bulk. François started his career in Bordeaux, working in the cellar at Château Lafite-Rothschild. In 1990, soon after the Costières de Nîmes received appellation status, François was inspired by the potential to make great wines from this little known appellation and he moved back to run the family winery. The first vintage bottled under the Château Mourgues du Grès name was in 1993.

The Costières de Nîmes is the southernmost region of the Rhône Valley. The terroir is influenced by the Rhône and the Mediterranean Sea. Like most of the southern Rhône, there is abundant sunshine, the weather is hot and mostly dry, and the Mistral wind helps to keep the vines healthy. The vineyards are covered with galets, the same round, flat stones that are famous in Châteauneuf-du-Pape. The Costières de Nîmes is unique within the Rhône region because of the influence of the Mediterranean. The sea cools the nighttime temperature, giving the wines a lot of freshness.

François and Anne are both very passionate about nature. They have practiced organic agriculture since 2004 (certified in 2011); meticulous care and attention are paid to the work in the vineyards. François and Anne Collard never rush to make changes, but at the same time, are constantly searching for the best way to manage their vineyards to get a very pure expression of the Costières de Nîmes. In 2018, they began the process for biodynamic certification and from the 2020 vintage, the wines are certified.

Like the work in the vineyards, in the cellar, all decisions are carefully taken with the aim of getting the best expression. For the Collards, this means making wines in a natural way while maintaining a classic style. Whites and rosés are fermented and aged in stainless steel tanks; the reds are fermented in cement so that there is an oxygen exchange, and then are aged in cement or barrels depending on the cuvée. Since 2015, no sulfur is used during vinification or aging on any of the wines, only a small amount at bottling. Total sulfur used is approximately 50mg/L on the whites and rosés and 40mg/L on the reds. Making wine without sulfur has its challenges, but it is worth the risk for all that is gained in greater fruit purity.
