The Comprehensive Sensory Training Kit offers the most important flavors and aromatics found in beer. It is composed of 25 vials, each with a specific flavor and concentration that allows for spiking 1 liter of beer. While breweries with established tasting panel structures will find this kit extremely valuable, it can also be used for “taster calibration” by brewers’ guilds, homebrew groups and beer judges. Visit the Siebel Sensory Station YouTube channel for a complete library of instructional and tasting videos.
