As it's a while since i last tackled anything from '85, I thought I'd indulge one.
Decanting was very slow, as the bottle had at some point in its life been stored on it's head, with the result that flakey sediment immediately emerged, blinding my decanting funnel..

Colour very dark - in the decanter almost black.
First sip - no bottle stink, fruity, classic Fonseca - very promising.
D + 12 Lovely nose, fruity wine.
D + 24 Little changed, excellent sipping.
But this is nowhere near mature, another ten years at least is required.
This is a classic Fonseca, one of their greats. To score it almost warrants a 9 for immediate gratification, but I'll give it an 8 for being so immature still.
This could easily earn a ten score in a few years time, but for now I'll be a little more cautious
Score 8-9
