Produced and bottled in the 1960s, this Four Roses Imperial Quart was unavailable in the US, like all whiskey that was produced by Four Roses at that time. The imperial quart is equal to one quarter of an imperial gallon, or exactly 1.1365225 liters, just in case you were wondering how much you are getting by purchasing this bottle of old and rare bourbon. The Four Roses Imperial Quart was partly made in the famous Four Roses Distillery in Indiana, which is known as MGP these days. As a blend of straight whiskies and grain neutral spirits, it probably tastes like ass. And of Four Roses export history!
