Milam & Greene Unabridged Volume 3 is a cask strength bourbon bottled at 59.0% ABV. As a bourbon, it is made primarily from corn and is presented at full proof, so it will usually taste richer, fuller, and more intense than a lower-strength release.
For a novice drinker, expect a bold style with concentrated oak, sweetness, and spice, along with a warming finish from the higher alcohol. A small splash of water can help open it up and make the aromas and flavours easier to explore.
