Sena produces red wines in Chile's Aconcagua Valley, a region defined by its warm continental climate and elevation. The winery's flagship, Rocas de Seña, blends Shiraz, Cabernet Sauvignon, Grenache, Malbec, and Petit Verdot into a structured wine that has earned recognition from Wine Advocate, Decanter, and Wine Spectator. The Aconcagua Valley bottling—built from Carménère, Malbec, Cabernet Sauvignon, and Petit Verdot—offers a complementary expression of the region's dark-fruit character and tannin depth. Both wines reflect the valley's capacity to ripen Bordeaux and Rhône varieties while maintaining acidity and complexity. The blending approach here prioritizes balance across multiple varietals, a strategy well-suited to Aconcagua's variable microclimates and vintage conditions.
