Wine sediments

[Kayden]

Ok, As long as every one agrees that I should open her, I'm doin' it (for new years). The wine (looking through the bottle) is as clear as day. Just Powdery/dusty (not chunky) debris built up, on the bottom/side of the bottle. Will have a backup bottle anyway. It's a 79' Pieroth Kabinett (K. Ferdinand Pieroth).

I've had this Wine stored since I was 14, no kidding '(mothers' divorce deal) so I've stored it ever since, and understanding the deteriation level of wine, I Just need some confidence from you guys, that the time is now, to open this Wine!..

Thanks, A very important decicion for me!
