What are the best bottled in bond bourbons that are reasonable to come across?
"Bottled in bond" doesn't really get you anything if you're proficient in TTB "label-ese" and have a working knowledge of the various distilleries and their products. In essence, all it means is that the spirit in the bottle was distilled at a single distillery in a single year and barreled at 100 proof for four years (or more).
Hell, Old Forrester markets a bottled in bond bourbon. So does Beam.
