This is solid intorductory information and history for anyone interested in mixology. I recommend it for new bartenders to get the basic facts down. i.e. distinctions between whiskeys, the origins of many varieties of liquors, etc. Customers ask a lot of questions and part of a bartenders job is to educate to the extent that it's possible. Not every bartending situation is the same. Some of this is more usefull in certain situations than others. I would definitely reccomend it for someone who is working in a slightly more upscale/dining situation where knowledge is part of the job. As far as instruction goes, well there is no way to learn how to do something via a podcast, you have to simply walk behind the plank and do it. To be sure, none of this is of much use when you're in the weeds serving a bunch of amateurs, cutting off badly behaved people, bandaging bleeding fingers, what to do when someone hands you a ten and claims it was a twenty, what to do when you break a glass in your ice well and its 3 deep at the bar, and everything else that comes with the job. Nonetheless, it's beneficial for anyone working in the industry to actually know a thing or two about the science and history of booze for the times when you actually do get to engage your customers in polite conversation, and this is a good primer to get your feet wet.
