Aletta operates in Campo de Borja, the Aragonese region celebrated for its bold, structured Garnacha. The winery's portfolio centers on this signature variety, with Granate Garnacha standing as its flagship expression. Wine Enthusiast and Wine Advocate have both assessed the winery's releases, with Granate earning particular recognition among the lineup. The region's high altitude and continental climate shape wines of depth and concentration—characteristics evident across Aletta's Garnacha-focused range, which includes Veraz Garnacha and a core bottling under the varietal name alone. Campo de Borja's terroir produces Garnacha with dark fruit intensity and mineral backbone, qualities that define the winery's approach to this traditionally Spanish expression.
