Bay rum may sound like something you'd pour in a glass over ice, but you're more likely to find it in a shaving soap. Older recipes called for clove, bay and pimento oils combined with a good bit of rum, while more current recipes add some citrus notes, like lime, and other spicy scents, such as cinnamon. The result is a fresh, spicy and very manly scent. Bay rum is mainly found in shaving products, like soaps, creams and aftershave, but can also be found in lotions and colognes. While there are essential oil recipes that come close, most bay rum scents are fragrance oils.
