Port..how long does it last?

[winoweenie]

Rad, Vintage Port is normally in the 18 % range and residual is from 15-20 depending on the shipper. The alcohol AND the sugar are the reasons that VP take so long to mature and also why they last so long. Haven`t had a lot of experience with tawneys or LB`s but I agree with Foodie that several months for ANY port that`s opened has to have a severe negative effect. Try his idea. WW
