Modern Bar Cart what's shakin drinks fans? Welcome to episode 310 of the Modern Bar Cart Podcast. I'm your host, Eric Kozlick. Thanks for joining me for another interview episode where I track down the best and brightest minds in the spirits and cocktail world so that I can share their secrets with you. This time around. I'm joined once again by Dr. Kevin Peterson. You may recall him from his previous interviews here on the show, featuring his innovative Detroit cocktail bar and fragrance concept, Castalia and Sfumato, and his groundbreaking technical mixology book Cocktail Theory. I highly recommend those two interviews if you haven't already checked them out, but in this conversation, Kevin and I explore his latest project which involves sifting through several years of self reported customer cocktail ratings from his bar. But before we start crunching through these data sets, I think it's only prudent to limber up with a drink as a little preview of a topic we cover at length later in this conversation. This episode's featured cocktail is the perfect spicy margarita taken from Kevin's first book, Cocktail Theory. To prepare this recipe, you'll need 2 ounces of blanco tequila, 3/4 of an ounce of Curacao. Here Kevin recommends the Pierre Ferrand expression, 1/2 ounce fresh lime juice, 1 ML jalapeno tincture, 1 ML Serrano tincture and 1/2 ML Habanero tincture. Quoting directly from Cocktail Theory here, combine all ingredients in a set of shaking tins and and shake with 2 ounces of ice 4 to 5 ice cubes for 12 seconds. Strain through a tea strainer into a snifter glass and garnish with a dehydrated lime wheel. Dr. Peterson also goes on to write, flavors are not isolated single point sensations. They have both spatial locations like tip of the tongue, roof of the mouth, back of the throat and time evolutions. I used three tinctures to create an evolving time and space sensation of heat, as if a wave were traveling through your mouth from the tip of the tongue down your throat. Make three different margaritas using only one tincture at a time to feel the difference in timing and location of the three distinct pepper tinctures. End quote. By the way, if you'd like to play around with making tinctures like these at home, you can pick up some 151 proof Everclear or some other high proof grain alcohol and macerate some diced peppers in a small mason jar for a few days to a few weeks before straining them and filtering the tincture into eyedropper bottles for dispens. If you're like me, you'll discover the delightful differences in the flavor profiles of these pepper varieties and immediately start growing super hot peppers at home. Occasionally tear gassing your family out of the house when you try to make hot sauce. Or maybe you can just be a normal person and simply enjoy your perfect spicy margarita with that let's turn our attention back to the interview in this data driven conversation with Dr. Kevin Peterson. Some of the topics we discuss and include how winding down Castalia and Sfumato after a decade of service provided the impetus for this new project and why Kevin has set out to address a very different set of questions than in his last book, Cocktail Theory. Why? Matching a person with their ideal drink is very different and much more difficult, it turns out, from trying to make the optimal old fashioned or Negroni or daiquiri. This leads to a conversation about all the variables that go into cocktail sweetness, acidity, bitterness, booziness, effervescence, egg white spiciness and so much more. How does one begin to build such a high dimensional beverage algorithm in pursuit of aesthetic pleasure? We also discussed some of the algorithmic tests that good bar programs and bartenders can implement in order to zero in on guest preference more quickly. These include good menu writing, the classic bartender's choice speed interview, and the possibility for creating a guest profile with likes and dislikes. Along the way, we explore why spicy drinks might just be a trap, the sea change that I experienced the first time I tasted green chartreuse, the idea of perceptual thresholds in cocktails and in life, and much, much more. As always, I had a blast nerding out with Kevin and lucky for you, this is is a two part interview. So warm up your graphing calculators and enjoy this first half of our statistically significant conversation.
