Viñas produces wines from Mendoza, Argentina's premier wine region. The winery focuses on two signature varietals native to the region's terroir: Malbec and Bonarda. The Malbec, a dark-skinned grape that thrives in Mendoza's high-altitude vineyards and continental climate, represents the winery's core expression. Bonarda, a traditional Argentine variety, rounds out the portfolio with its own character and structure. Both wines have been assessed by Wine Enthusiast and Wine Advocate, reflecting their standing within the region's competitive landscape. Mendoza's elevation, mineral-rich soils, and diurnal temperature swings create conditions that favor ripe, structured reds—characteristics evident in Viñas's approach to these two grapes.
