Stellum Bourbon is a delicious prototypical high-rye bourbon that lives up to expectations. I had been waiting for Stellum ever since I heard it was being produced because I'm a fan of Barrell products. However, I had to wait until my third or fourth tasting to review Stellum. Frankly, I was not a fan of it my first two tastings, but since it was a Barrell product, I gave it the benefit of the doubt. In my experience, Barrell products always get better the longer they are open. I'm so glad I stayed with this bourbon which is a blend of three bourbon mash bills, two of which are high-rye.
