We think we know how to appreciate wine--trained connoisseurs take dainty sips in sterile rooms and provide ratings based on objective knowledge and technical expertise. In Epistenology, Nicola Perullo vigorously challenges this approach, arguing that it is the enjoyment of drinking wine as an active and participatory experience that matters. Perullo argues that wine comes to life not in the abstract space of the professional tasting but in the real world of shared experiences; wines can change in these encounters, and drinkers along with them. Just as a winemaker is not simply a producer but a nurturer, a wine is fully known only through an encounter among a group of drinkers in a specific place and time. Wine is not an object to analyze but an experience to make, creatively opening up new perceptual possibilities for settings, cuisines, and companions.
