Chateau la Tour de Mons 1966

[BlondeBuffoon]

Greetings my wine drinking friends!

Firstly, I want to say thank you for all the excellent information I have read on this site over the past few weeks. I have just started developing an interest in wine since a friend gave me a bottle at christmas.

Now, I have a bottle of Chateau la Tour de Mons, 1966 vintage. I understand that la Tour de Mons is a well-respected vineyard that is allowed to use the appellation of Margaux. I also understand that 1966 is a good vintage. My question is, should I drink up this bad boy asap or can I hold it for a little while longer? Also, do you have any idea of its value? This might be a foolish question, but what grape variety is it likely to be?

I also have a bottle of 1977 Laurent Perrier champagne (extra dry) which was made for Queen Elizabeth II's Silver Jubilee. My questions are simlar: when should I drink it and is it valuable? I used to have two, but I drunk the other around a year ago and it tasted great (in my opinion).

These are both the oldest bottles I possess, and they look great in my rack! The idea of opening one seems like sacrilege. Of course I don't want to leave them too long, only to find that they are over the hill (if they aren't already).

Thanks again and greetings to you all from a surprisingly sunny London!
