Many retailers select custom barrels in the Maker's Mark Private Selection series; this one is "Bev Max Edition #1", stave profile 1-2-2-4-1, bottled at 109.5 proof in February 2021. Very similar clear reddish mahogany color to the Maker's 46 that immediately preceded it. The nose is more focused and less plush than the MM46, showing carrot cake, butter pecan ice cream, Golden Grahams cereal, a whiff of molasses, and a dusty note. The wood jumps out on the palate, which has a wonderful, oily mouthfeel where the flavors explode, buoyed by the higher proof, which is well-integrated. Loads of vanilla on the finish which lingers like a long country road. 4.25 on the Distiller scale. I don't recall the price I paid for this--perhaps $60?--and while these Private Selection bottles aren't as polished as some of the other MM wood-staved products (FAE-01 and -02, BRT-01 and -02) in my experience, they're always reliable, and unique given the custom stave profile, offering a differentiated drinking experience. N.B.: All spirits tasted neat in a Glencairn glass.
