I have a similar (though certainly more basic) question regarding Tawny Ports. I just recently received a bottle of 20-year Tawny, and I know there is essentially no chance that we will drink this bottle within a week.

Once I open this puppy, what is the preferred way to store (fridge?), and how long is it suitable for drinking after opening? I've heard everywhere from a week to six months, and, frankly, both seem a bit questionable to me.

Thanks. And let me say that I really enjoy reading these various threads on the WindBoard. While many topics are way, WAY, over my head, I feel I am soaking up quite a bit by just reading these various topics.
