Barletta is located in Clare Valley, a subregion of Mount Lofty Ranges in South Australia known for its cool-climate viticulture and mineral-driven wines. The winery produces Grenache, a variety that thrives in the region's distinctive terroir. Barletta's Grenache has earned recognition from Wine Spectator and Wine Advocate, reflecting the wine's structure and balance. Clare Valley's elevation and diurnal temperature variation create conditions suited to Grenache's ripening, yielding wines with both depth and freshness. The region's limestone soils and continental climate have long supported quality fruit production, and Barletta's focus on this varietal demonstrates the potential of South Australian Grenache.
