Ognissole works with the native grapes of Puglia, the sun-soaked region at Italy's heel. The winery's portfolio centers on three distinctive reds: Essentia Loci Primitivo, a wine built on the dark-skinned Primitivo variety; Negroamaro, named for the grape that defines much of southern Puglian viticulture; and Magnus Nero di Troia, which draws from one of the region's historic cultivars. Each reflects the terroir of this warm, Mediterranean corner of Italy. Wine Advocate, Wine Enthusiast, and Wine Spectator have all assessed the winery's releases, with the Essentia Loci Primitivo earning particular recognition among prestige critics. Puglia's continental climate and limestone-rich soils shape wines of depth and structure—Primitivo and Negroamaro both tend toward ripe fruit and bold tannins, while Nero di Troia brings its own mineral character to the lineup. Ognissole's focus on these indigenous varieties anchors the winery to its place.
