Who would think that rose could be used as a botanical in gin? But the damask rose, so named after Damascus in Syria from which it originated, is often used in the creation of liqueurs, perfume and gin through the processes of infusion and distillation.
Frankincense is one of the noblest gin botanicals. Its name derives from the Old French for 'noble incense'. Used for centuries in religious ceremonies it is now being distilled in gin. But beware. Too much of the noble incense and your gin can taste like men's soap.
