THE COMPLEXITY OF ALCOHOL FOLLOWING THE TRAIL IN LOUISVILLE AND NAPA VALLEY AUTHOR Tom James, MD W hat makes one bourbon better than another? What makes one wine superior to grapes of the same varietal? It’s not really about the alcohol, although that does play a role. Instead, it has to do with the taste, the nose, the body, the look and the general expe- rience one has with that beverage. At the most elemental level, the process of making a bourbon or a wine involves yeast, fermentation and storage. However, for bourbon the emphasis is more on the corn percentage and the wheat or rye in the “mashbill” and the storage. For wines, it has to do with the varietal of grape, the environmental factors of grape growth and the sugar content. Therefore, it only makes sense that the manufacturer of bourbons and wines highlight those aspects of production that make its product unique. 16 LOUISVILLE MEDICINE The Kentucky Bourbon Trail and Louisville’s Urban Bourbon Trail focus on displaying the process of fermentation and storage. It involves the management of these processes that give bourbons their individual character. Unlike with wines, the nature of the organic substrate is not as important. No one would include a tour of a cornfield or show waves of wheat or rye blowing in the wind. However, in Napa Valley the highlights of the vineyard tours are seeing the different varietals growing in unique sections of each vineyard. Typically, the Napa Valley guides are effusive about the subtleties of soil, drainage and climate in adjacent acres. These basic differences help to frame the backdrop to Louisville’s Urban Bourbon Trail and the Napa Valley Wine Trail. Early this past summer, I brought a bourbon-naïve Pittsbur- gher to Louisville. Traveling Main Street gave us the opportunity to enjoy the experience of the Urban Bourbon Trail from different vantage points—one of a local native and one from a bourbon-in-
