Alicante Bouschet, Trincadeira, Grand NoirAppointment onlyCasa Branca, Sousel
A 900-hectare cork and vine estate near Sousel farmed by the Reynolds family since 1901, still foot-treading Alicante Bouschet in open stone lagares and ageing it in century-old wooden vats.
DOC Alentejofield blend old vines, Grand Noir, Tinta GrossaFounded 1878Reguengos de Monsaraz
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.
