Women May Have Biological Edge in Tasting Bourbon, Experts Say
Scientific evidence suggests women possess a keener sense of smell and taste, potentially offering an advantage in appreciating the nuances of bourbon.
A theory within the bourbon community posits that women may possess a superior ability to taste the spirit compared to men, a claim supported by some experts who point to scientific evidence. This advantage is largely attributed to differences in olfactory perception.
Whiskey expert and author Susan Reigler stated that women generally have a keener sense of smell and taste. Reigler, a former president of the Bourbon Women organization, referenced a 2014 scientific paper that examined the olfactory bulbs in men and women. The study indicated that women have nearly 50% more neurons in their olfactory regions than men, which could contribute to a more acute sense of smell.
Caitlin McLean, vice president of Qualitative Solutions at MMR Research Worldwide's North American offices, noted that factors beyond smell influence taste perception and can affect men and women differently. She highlighted the roles of orthonasal and retronasal olfaction in the tasting experience. Orthonasal olfaction involves smelling aromas directly, while retronasal olfaction occurs when aromas travel from the back of the palate to the nose from within. McLean explained that key bourbon characteristics, such as notes of vanilla, cinnamon, leather, smoke, and dark fruit, are identified through retronasal olfaction. The complexity and finish of bourbon, which significantly contribute to the overall enjoyment, are heavily influenced by this process, as the palate's taste capabilities are limited.
Hormonal factors, particularly estrogen, are also believed to play a role, as estrogen has been linked to a heightened sense of smell. McLean pointed out that hormonal fluctuations, such as those during pregnancy or menopause, can lead to noticeable differences in olfactory sensitivity.
While the idea that women are biologically predisposed to have a stronger sense of smell to protect their offspring is a theory, McLean noted that it is difficult to prove scientifically, though some evidence supports women outperforming men in olfactory tasks on average.
Historically, women have also held significant roles in bourbon production. Reigler mentioned that tasting and quality control panels at Kentucky distilleries have traditionally been predominantly comprised of women. She added that while men can also be excellent tasters, developing exceptional tasting skills for anyone, regardless of gender, requires practice.
