Perescuma operates in Alentejo, Portugal's expansive southern wine region, where warm continental conditions and diverse soils support ambitious red blends. The winery draws on indigenous Portuguese varieties—Touriga Nacional, Aragonez, Alicante Bouschet—alongside international grapes like Cabernet Sauvignon and Shiraz to craft structured wines. No 1 Reserva Tinto, a five-variety blend anchored by Cabernet and Shiraz with Portuguese depth, leads the portfolio. Orquestra Reserva follows, balancing Touriga Nacional's dark fruit with Alicante Bouschet's tannin and Cabernet's frame. The entry-level Tinto rounds the range, blending Aragonez, Shiraz, Cabernet, and Alicante Bouschet into an accessible expression. All three have been assessed by Wine Enthusiast, Wine Advocate, and Decanter, reflecting the winery's engagement with prestige critical standards. Alentejo's scale and terroir diversity allow for experimentation; Perescuma's approach emphasizes varietal complexity and balance across its tiers.
