This is what good wine from the Tintilla de Rota grape tastes like

Tintilla de Rota is a rare dark-skinned grape from southern Spain that produces fairly dark red wines with notes of plum and cocoa. Several winemakers dry the grapes slightly and/or add alcohol during fermentation, making the wine sweet.

Tintilla de Rota originally comes from vineyards around the coastal town of Rota in Cádiz - right in the middle of Sherry country. In the eighteenth and nineteenth centuries, red wines from Tintilla de Rota had a great reputation. By the middle of the last century it had almost died out, because although it grows within the Sherry region, it is not permitted for making Sherry. You can only bottle wine from it as 'Vino de la Tierra'.

By now there are a number of leading winemakers in the region who have replanted Tintilla de Rota and make (excellent) wine from it. Most let the grapes dry slightly so they become relatively sweeter, and add alcohol during fermentation - after all, we're in Sherry country! This keeps the wine sweet.
