It is a mix of dry Oloroso (Palomino grapes from the Carrascal and Macharnudo areas) with 8-10% sweet, very old Pedro Ximénez. This results in a sugar contents of around 45-50g/l, which means the wine is off-dry rather than thoroughly sweet.
Valdespino Solera 1842 is a V.O.S. wine – it’s over 20 years of age, and more importantly: the wine spends almost half of its time as a blend. This makes the end result much more integrated and ‘naturally sweet’ than when the blend is brought together right before bottling.
