Jose de Sousa ★ 4.5
A 19th-century Reguengos de Monsaraz winery that never abandoned talha fermentation, its subterranean cellar of century-old clay vessels a living link to the Alentejo's Roman-era winemaking method.
Tip: Ask to see the talha cellar itself rather than just tasting in the shop; the neat rows of century-old clay vessels are the reason this producer matters.
