While bottling Barrell Bourbon Batch 007, we decided to keep a few barrels behind for research and development purposes. A month later, bottles of Barrell Bourbon Batch 007 had flown off the shelf faster than we ever could have imagined. And so, back to the old, Old Taylor warehouse we went to load up the remaining barrels of Batch 007 and truck them down to the bottling line. When we tasted them again, something had changed. In a mere 14 weeks the onset of summer, the agitation of two truck rides, and the general mystery of Bourbon maturation had taken hold. We had a much woodier, mellower Bourbon at a slightly lower proof. This was not our light and buttery Barrell Bourbon Batch 007 anymore, but it still WAS barrels from batch 007... and Batch 008 was already on the way. Our solution? Barrel Bourbon Batch 007b, our smallest batch yet.
