Cellers Sant Rafel operates in Montsant, a subregion of Tarragona in Catalunya known for structured red wines built on indigenous and international varieties. The winery's portfolio centers on blended reds that marry Carignan and Grenache—grapes native to the region—with Cabernet Sauvignon and Merlot. Solpost Negre, a Carignan-Grenache-Merlot blend, leads the range. Solpost Tinto follows, anchored by Cabernet Sauvignon and Grenache with Carignan, while Solpost Fresc balances Merlot, Grenache, and Cabernet Sauvignon. These wines have been assessed by Decanter, Wine Enthusiast, Wine Spectator, and Wine Advocate. The house style reflects Montsant's terroir: wines with depth and complexity drawn from the region's schist soils and continental climate.
