I still need to research cognac...
I'd be interested in where it takes you. I would like to get a nice bottle when winter rolls around here again. That would also mean I would have to get a balloon glass to do it properly.
I'm keen on trying a few ports as well, as I have not had one in years.
I've also been considering getting a LBV Port for my 50th and aging it for enjoying on my 60th.
