I haven't had Maker's 46 in years. I recall trying it over a decade ago when it first came out, and I loved it. Since then, I've been weaving and wending my way through the vast world of whisk(e)y, and had not thought much about it--especially given Maker's Mark's continued development of the wood-stave finishing process that was started with MM46, leading to the amazing FAE-01 and -02, and BRT-01 and -02, among others.
I had this unopened bottle hidden behind several others and decided to open it. What a pleasant surprise! It was everything I remembered.
Clear red mahogany color. Cinnamon, pound cake, vanilla, banana pudding, dried orange, pepper, and a pleasant sawdust on the nose. Young wood on the palate, where the ethanol makes an appearance on the back end, smoothly. The 94 proof goes down easy, with some pleasant oak on the finish. Not terribly complex, but very good--and a fantastic value in today's market at ~$40. 4.0 on the Distiller scale.
As the photo shows, mine is the old-style bottle; I've not yet had the newer one yet, but very much hope it's the same. MM is widely available, so as soon as this one gets low, I'll grab a new one. But with as much bourbon I've got in the barn, that's not going to happen soon. ;)
N.B.: All spirits tasted neat in a Glencairn glass.
