I recently discovered an unopened bottle of St Germain that was originally purchased at the tail end of 2008. It has been in a temperature-controlled environment for the past 4+ years. Is this still good for drinking? I have heard that unopened St Germain is only good for about two years, but am not sure if I buy that.
Otherwise, I am a cheap bastard, so I suppose the second part of that question would be if it's not still "good," is at the very least safe for a less discerning drinker?
