closed wines?

"Auslese godcap 95 Elegant wine, with good acidity, a bit closed."
"Diel: Auslese Goldcap 95 Nose seemed closed, a hint of rhubarb "
"Riesling Kabinett trocken '94 Somewhat closed nose. Near Spaetlese density"

Talking about wines, what do they mean by "closed"?

It means the wine is lacking in character because it has not aged sufficiently.

Speaking of wine...
What does it mean when a wine bottle is "poled"??
Don't ask for the context because a friend of a friend asked the question.
