What to Expect
This slate mill wine collective offers a blend of Cabernet Sauvignon, Barbera, and Malbec grapes. While specific origins are unknown, these varietals come from regions known for their distinct characteristics—Cabernet Sauvignon for its full body and dark fruit character, Barbera for its high acidity and Italian-American heritage style, and Malbec for its deep color and plummy flavor profile. Expect a nuanced and versatile selection that reflects the collective's commitment to quality and diversity in wine.
