Got into the Stille Nacht on Christmas. '08 purchase this year with 'bottles in 2008' sticker on it was pretty meh. My perception threshold for wet paper/cardboard is very high, but even I picked it up here. '12 I've had cellared since purchase was in fine shape, but probably not the best year to begin with. Opened an SNR10 that was the first not great bottle I've had. Cork was about 3/8" past the lip and had beer on top of it and was soaked. Cap was black underneath. Not awful and thankfully not overly acetic, so it was still enjoyed, but undercarbed and lacking the depth and roundness that's made this one so enjoyable before. Still have '13-'15 Stille Nacht in the fridge we didn't get into.
