Bosinakis operates in Mantinia, the high-altitude heart of Arkadia in Greece's Peloponnesos region. The winery focuses on Moschofilero, the indigenous white variety that defines the appellation. Grown at elevation, Moschofilero develops crisp acidity and mineral character—qualities that anchor Bosinakis's flagship Mantinia Moschofilero. The wine has drawn assessment from major critics including Wine Advocate, Wine Spectator, and Wine Enthusiast. Mantinia's cool climate and limestone soils create conditions suited to aromatic, food-friendly whites, and Bosinakis's expression reflects the region's capacity for precision and balance.
