Although Jensen's Old Tom is a faithful reproduction of an 1840s recipe, it is unique on the modern day gin market in that it is unsweetened, & in fact Christian Jensen found historical evidence that this is the most accurate recreation of the Old Toms that were being used in cocktail making in the 1800s. It is rooty, intensely complex & a fantastic base for many a cocktail, as well as making a divine gin & tonic!
