Had an 09 on draught a few months ago and thought it held up great, only difference being it was a bit thinner than I remember.
I had it with a few years on it and I thought it didn't drink as well as I had remembered. Some of the nice maple flavor in there was completely gone.
I guess I just need to drink it to find out. Someone told me the brewers wanted to drink a batch one when both of their kids were of legal drinking age. That would be around 15 yrs or so
I went to a bar in Brooklyn in October and they had SN Life and Limb B1 (and Limb and Life) kegs on tap from a vintage event. I thought Life and Limb had held up pretty well over the years. I agree it isn't as maple-y, as I remembered it having a lot of maple, but I still enjoyed it quite a bit.
I just opened a Life and Limb 2011 thinking it was going to be creeping past its prime and it was UNBELIEVABLE, I wish I held onto it longer
