Four Roses is one of my favorite Kentucky bourbon distillers. The regular Single Barrel hits the sweet spot for me in terms of flavors, proof, and price. I like the higher-rye mash bills that they use. I have an open bottle of the Single Barrel Barrel Strength that I poured next to this one to compare. The sample of the LESB was generously provided by the venerable @PBMichiganWolverine The color of the LESB is quite noticeably darker. On the nose, the LESB actually doesn't distinguish itself from the SB as much as I expected. It's a punchier version of the SB, and perhaps shows more sweetness, balanced with wood and a little rye herbalness. The palate is a different story. Vanilla, buttery caramel, cherry, clove, mint, slightly herbal. Great balance. In comparison, the SBBS I have open (which I think is pretty good) comes across as flat, bitter, and unbalanced. Really pleased to have had the opportunity to try this one. Big thanks, Pranay!
