Heaven Hill introduced Elijah Craig Barrel Proof in 2013, and have since released three new batches each year. The first letter of the batch number indicates which of that year’s releases the bottle was a part of (A, B, or C). The second digit indicates the bottling month, and the third and the fourth the year. This is the February 2015 release of Elijah Craig Barrel Proof, aka Release #7, aka Batch A215. The bourbon aged for 12 years, before being bottled straight from the barrel at 128 proof.
