Setubal Desert Wine

Setubal - 20yrs - desert wine - produced by Jose Maria da Fonseca - Portugal - 18%
Grapes: Moscatel de Setubal, Boal and Malvasia
No vintage on the bottle, but bought around 1997, so the wine is around 30 years.
Wow, what a dessert wine - complex, extremely sweet, nutty, dried raisin, fig and candied orange, sweet grape (from the Moscatel). Reminiscent of both Oloroso Sherry and LBV Port.
Totally unique flavours for a dessert wine, must have again if I can ever find it!
Perfect accompaniement for Foie Gras.
