Bodegas Toro Albalá, Don PX Pedro Ximénez Gran Reserva, 1990

Wow! Dried grapes are fermented as far as possible (this has 387g/litre of residual sugar) then lightly fortified and freshened up with some Amontillado before ageing for 28 years in old US oak butts. Complex, rich walnuts, spiced rye, dried fruit, iodine, coffee, liquorice and treacle. Try with dark chocolate or pour over ice cream.
