Hi,
I realise this isn't really the correct NG, but can find no other in use
that is similar.

I have been given three bottles of wine A chateau neuf du pape 1976, St
Emillion 1973, and another which I don't have the name of but will get later
1976. I don't know the vineyeards of the top of my head. But is there
anywhere online I can find if the wine is likely to have kept, what to look
for in the wine, or if it is likely to be vinegar.
They've been stored horizintally in a basement for the last 25 years, and
the colour looks OK, except one which is quite light.

or is it all a gamble?

Thanks

Ali
