Celler El Masroig, located in the up-and-coming region of Montsant, is a role model for how a cooperative ought to function. The winery keeps only the best grapes and sells off the rest to other producers, some of whom are quite well known. The wines are very fairly priced and offer an excellent price to quality ratio from the top to the bottom of the portfolio.
Celler el Masroig is situated in the southern part of Montsant, bordering on Priorat. Montsant, which became a DO in 2001, extends from the banks of the Siurana River to the Montsant hilltops. The soil is mainly chalky, with some areas of clay and shist, all with high mineral content and low yields. Because it is located on the border of the Mediterranean and the continental climates, the summers and winters are dry while the springs and falls are moist.
Celler el Masroig was founded in 1917 as the Cooperativa of El Masroig. It is an association of grape and olive oil producers with approximately 300 members who are associated owners of the company. In the early years of the Cooperativa, the focus was on producing quantities of wine rather than quality wine. They produced wines with high alcohol content and very deep color that were sold to the domestic market and often used to "improve" other wines. Then followed a period in which the major products were mistelas -cordials made from red wine, and grape spirit.

Solà Fred is a blend of 90% Carignan and 10% Grenache.
