I’m first! Four bottles of B521 on the shelf in SW Michigan this evening. Grabbed two....neck pour very nice....easy on the nose, no blast of ethanol. Let it sit for 30 minutes, then gave it a go....easy drinker as one might expect at 118 proof. Good balance of oak, spice, and sweetness....not super viscous, but hits right down the middle like a nice line drive, with all the ECBP characteristics and quality that we all expect, sans the HazMat proof. Liking this....has a very nice oak backbone without being bitter. If you want to be overwhelmed with flavor and proof, then this ECBP isn’t it. If you are looking for a premium Whisky at less than a premium price, then look no further. Feeling like this could be a great go-to drinker all summer long....could definitely drink this on an 85° day. B520 is superior to B521 based on the first date, but no regrets in grabbing two of these. A very nice change-up if I must continue with the baseball metaphors. Simply stated, this is good Bourbon.
