Domaine du Cros has been in the Teulier family since 1882 and is today guided by fifth-generation Julien, who has steered the estate toward organic and natural viticulture while cementing its status as the reference producer of the Marcillac AOC — an appellation of fewer than 200 hectares in the Aveyron that was nearly extinct by the 1960s and owes much of its survival to this single domaine. The Vieilles Vignes cuvée is made entirely from Fer Servadou, locally known as Mansois, sourced from vines over 50 years old planted on steep hillsides atop the appellation's signature rougier soils — ancient Permian red clay rich in iron over a limestone base — the terroir that lends Marcillac its unmistakable mineral streak and trademark peppery lift.

Grapes are fully destemmed and gravity-fed into tank, where an extended maceration of around 35 days with regular pump-overs and délestage builds both structure and depth; the wine then rests for 12 to 18 months in large, well-seasoned 3,000-litre foudres before being bottled roughly two years after harvest. The 2020 vintage is widely regarded as one of the most complete and concentrated in recent memory, and this bottle delivers on that reputation with dark ruby colour, aromas of blackcurrant, blackberry, mint, graphite, black pepper, and liquorice, supported by fine-grained tannins, vibrant acidity, and a long mineral finish — a serious, characterful wine that drinks beautifully now and has the structure to reward cellaring through 2030, all for just €15.05.
