Casa Solar produces Tempranillo from Castilla, Spain's vast central plateau. The region's continental climate—hot days, cool nights, high altitude—shapes wines of structure and precision. The winery's portfolio centers on Tempranillo in varied expressions: a rosé that captures the grape's bright red-fruit character, a three-month barrel-aged version that adds subtle oak influence, and Plata, a lighter interpretation. Wine Enthusiast and Wine Spectator have rated these releases, with the rosé and barrel-aged bottling earning particular recognition. Castilla's terroir favors Tempranillo's natural acidity and tannin framework, and Casa Solar's approach reflects the region's tradition of straightforward, food-friendly reds and rosés.
