Someone else has recently started a thread on age stated bourbons, but I want to go the other direction. Of those common but well thought of bourbons we all drink, just how much barrel age do they have? Ones I'm specifically interested in are OGD BIB and 114, 4R SmB and YL, and OFS BIB. In particular, the OFS BIB tastes at least 8 yo and could even be 10 by my palate. Please give the source of your info, and how sure you are it is authoritative. Thanks much.
