Who are the Commando G producers rediscovering Garnacha?

The new generation of wine producers in the Spanish wine region of Gredos are part of a movement called Comando G – responsible for driving an exciting rediscovery of wines made out of Garnacha grown on granitic soils. Commando G held a masterclass in London called Breaking Buds to showcase these producers and their wines. Connie Hunter reports on which producers and wines shone on the day.
