The Mas d'en Gil winery is located in the Catalan town of Bellmunt del Priorat in Spain. Its history began around 1860, when the businessman, journalist and farmer Francesc Gil acquired the estate in the Priorato region. 

After his death, his descendants took care of the estate until it was taken over by the Barril family in 1930. The Barril family changed the name of the estate to Masia Barril. Rafael Barril Figueras and his son Rafael Barril Dosset, together with Magdalena Vicente Jordana, made the groundbreaking decision to grow wine on the estate's lands and bottle it for sale.

In 1998, the Rovira Carbonell family bought the estate and gave it back its historic name. Around 2000 the first Mas d'en Gil wines appeared.

Mas d'en Gil has 125 hectares of vineyards planted with Garnacha Tinta (locally called Lladoner Pelut), Cariñena and Syrah. The mineral-rich slate soil gives the wines, which are produced here surrounded by the Montsant and Serra de Llaberia mountain ranges, a special complexity. The winery is now run by Marta Rovira Carbonell. It is also responsible for the introduction of organic farming methods in the vineyards. She is assisted by her father Pere Roviras and her older sister Pilar.
