GR-10 is named after a hiking trail that connects the Atlantic and the Mediterranean and runs through the Sierra de Gredos. It’s the entry-point red from 4 Monos (their whole range is worth buying) and is a pale, tangy, refreshing cuvée of Garnacha with 10% Cariñena and 5% Syrah. Mostly aged in foudres, with a touch of new, 500-litre oak, it’s a wonderfully refreshing, high-altitude red from vineyards in Cadalso de los Vidrios, San Martín de Valdeiglesias and Cenicientos showing bramble, red cherry and raspberry flavours and refreshing granitic grip.
