Reginato produces wines from Mendoza, Argentina's premier wine region. The winery's portfolio spans sparkling and still wines across multiple varietals. Its Brut sparkling wine has drawn attention from major critics including Wine Advocate, Wine Enthusiast, and Wine Spectator. The Celestina Rosé of Malbec showcases the region's signature dark-skinned grape in a dry rosé format. A Torrontés-Chardonnay blend rounds out the core range, pairing the aromatic white varieties that thrive in Mendoza's high-altitude vineyards. The winery's output reflects the diversity of Argentina's most established wine region, where elevation and continental climate create conditions for both structured reds and crisp whites.
