Kevin Peterson is a unique blend of perfumer by day and mixologist by night. He runs Sfumato Fragrances, where he began his career, but his journey took an interesting turn when he opened Castalia, a craft cocktail bar in Detroit. At Castalia, Peterson not only serves drinks but also creates cocktails that are designed to harmonize with specific aromas. His exploration into mixology led him to write Cocktail Theory: A Sensory Approach to Transcendent Drinks, which encapsulates his extensive experiments in creating the perfect cocktail matched with the science of scent.
Peterson’s career path has been anything but conventional. He started out as a line cook and auto mechanic before pursuing culinary arts, then transitioned to earning a degree in physics and a PhD in mechanical engineering. After a decade in engineering, he reignited his passion for perfumery, which eventually led to the establishment of Sfumato and Castalia, allowing him to combine his interests in both scents and flavors.
Over the years, Peterson meticulously studied the interactions between scent and flavor, perfecting the ratios and components of classic cocktails in search of their "Platonic ideal." He incorporates feedback from customers at Castalia into his research and writing, resulting in a comprehensive dive into cocktail chemistry and enjoyment, encompassing flavor profiles, textures, and presentation. His book provides not just theoretical insights but also practical advice for home bartenders, including recipes and tips for building a personal bar.
Peterson’s approach introduces a scientific perspective to cocktail creation, notably through what he refers to as the "Mr. Potato Head" theory, which emphasizes the substitution of ingredients based on their roles rather than their specific identities. This method allows for experimentation, encouraging both amateur and professional mixologists to consider new ingredient pairings while maintaining the essence of classic cocktails.
When discussing the integration of scent into cocktails, Peterson highlights the parallels between perfumery and mixology, where building flavors and aromas can significantly enhance the drinking experience. He emphasizes motifs and intentional themes in drink creation, suggesting that each component should embody a purpose, whether spotlighting a particular ingredient or achieving a harmonious blend.
In his experiments, Peterson surprises patrons with unconventional combinations, demonstrating how seemingly incompatible ingredients, such as blueberry and horseradish, can work together deliciously. He also shares insights on trends in cocktails, including achieving consistent smoky flavors and the subjective nature of taste. He acknowledges differing preferences and sensitivities in flavor perception, advocating for a personalized approach to cocktail creation based on customers’ individual tastes.
Peterson’s philosophy extends beyond mere flavor; he also views cocktails as narratives. By thematically linking drinks to stories or concepts, he enhances the customer experience, making it both memorable and engaging. His practical advice for aspiring mixologists is simple: start with a drink you enjoy, and gradually expand your palate with new ingredients, ensuring an enjoyable journey into the world of cocktails.
