From their website:

"Uncut, straight from the barrel without chill filtering, the nose, taste, and finish created by twelve years of aging are preserved in their simplest form. At full barrel proof, you can enjoy Elijah Craig much the same way our Master Distillers do when they sample straight from the barrel in our Kentucky rickhouses. Elijah Craig Barrel Proof is a bold and honest expression of what charred oak barrel aging can do for Bourbon, from the man who originated the process.

Reality: Varies by Release
Barrel Proof Batches

Each batch of Elijah Craig Barrel Proof is an uncut Small Batch of 12-year-old Bourbon bottled straight from the barrel. The variance in proof from batch to batch presents a unique opportunity to explore the impact of the angel's share and the resulting proof in a small batch of barrels.

The first letter of the batch number indicates which of that year's releases the bottle was a part of starting with "A", while the second digit is a number that determines the month of the year the bottle was released. The third and fourth digits indicate the year".

Absolutely honest and direct.

Now, I am going to throw in my two cents. This is a fantastic deal on high-quality bourbon. I have had multiple Barrel Proof Elijah Craig and they were always great. I am glad that Heaven Hill moved to this concept and think you will be too.

Since they are all different (yet readily available), I am not going to post detailed tasting notes, but here are quick notes from the small sample I had.

So the ONE I am tasting is from Jan 2017---
N: High, tight fruit candy/hard candy.oak, dried flowers, and stone fruit

T: Follows the nose that with emphasizes vibrant, spices and round fruit

F: The finish carries on with the aroma and flavor structure with a touch of warming alcohol made even more vivacious against strong the wood tones.

Great bourbon for fans of higher proof. Be careful when adding water, it is really easy to put this bourbon to sleep. That being said, I am sure it would sing with a bit of ice or in a lovely cocktail.
