The valley of La Geria, which has been declared a 'Protected Area', is Lanzarote’s main wine-growing region, occupying about 20 square miles (52 square kilometres) and stretching on both sides of the road from Masdache to Uga and right up to the volcanic slopes. This area produces most of Lanzarote’s excellent wines, of which 75 per cent are made from the Malvasía grape, one of the oldest known grape varieties. Best known as a honey-coloured, very sweet wine with a rich flavour, already praised by Shakespeare hundreds of years ago, today the Malvasía grape produces a wide variety of quality white, red or rosé wines, from very sweet to very dry.
