Grupo Peñaflor, Gran Mascota Malbec, Uco Valley, Argentina, 2021

Calling all Malbec lovers: don't miss this dark and delicious incarnation, new on the shelves at Tesco. It's the creation of Rodolfo Sadler, better known as Opi, one of Argentina's most well known winemakers. Made from fruit sourced from sites across the Uco Valley, the wine spent time in concrete vats before ageing for 18 months in second- and third-use French oak barrels. The result: a gorgeously plummy, glossy dark fruited red with earthy notes and a touch of vanilla. A perfect winter warming red.
