my former experiences with port are up untill now limited to drinking some cheaper (SUpermarket) Tawnys, and a few medium priced bottles like
Oporto 10, Dows LBV 1998 or a Barao de Vilar Vintage Charactere.
Now i went to a local dealer and purchased a Bottle of Warre's Vintage 1991 to celebrate with three good friends of mine.
We plan to drink the port after a good meal (we'll see what there will be) and have some tasty Red Wine with dinner. Afterwards the port.
For the preparations i have the standard question of decanting. I now found in the Board two opinions where this bottle was decanted once 5 once 19 hours beforehand. Now i'm not sure about how long to open it beforehand. As I dont have the experience of tastting how it should be perfectly i dont think i'll be able to decide when to stop the decanting if decantet too long as i will only recognize it when it has been much too long

For the decanting itself - do you usually decant free hand or through some kind of Muselin (or cheese) cloth / Metal sieve?
I planned to use my standard 1,5l decanter from Eisch and decant either directly or through some cloth. Im also not sure if i will just keep a part of the port stored in small 100ml flasks filled up to the top (1 or 2) or if I should just decant all and force me to drink it all within 2-3 days.
If you could answer some of these questions or if you have some additional advice i'd apreciate it.
Thanks, Xaverin
