This product tester job is an actual, paying job. Nice work if you can get it, a professional beer taster works for a specific brewery and travels to bars and pubs and ensures that its beer tastes the way it's supposed to.
This means making sure it's being stored and served correctly, as well as kept at the right temperature. The technical name for this job is "beer quality technician," and the job doesn't just entail tasting the beer. It also includes troubleshooting and pinpointing any issues with the keg lines or coolers [source: Merz]. Because of the technical aspects, this can be an on-call, 24-hour-a-day job. Beer tasters check their products for the perfect pour, the right clarity, taste and aroma. And if the beer isn't up to snuff, they can ask a pub to stop serving the beer until the problem is resolved.
