Melrose Rare is an American “blended whiskey”, composed of 40% 12 yo whiskey (bourbon, or the used wood parallel using bourbon mash) and 60% grain neutral spirits. “Back in the day”, i.e. the 1960s, 1970s, and early 1980s, when vodka was becoming king in the US spirits world, and Canadian Club was in the US the whisky model for “hard” liquor, there were a lot of these “mild” “mellow” “smooth” bourbon cousins on the market. There are still a few of these fossils around nowadays, but they have almost no popularity anymore.
