I have been seeing the term "beer expert" recently, mainly in the non-nerderatti press aimed at the general population. Like this:
IGA is proud to be working with beer expert Philippe Wouters to assist their customers in discovering a variety of flavours. Mr. Wouters has created an association system of colours and sensations available exclusively at IGA that indicates a flavour profile for every beer sold in store. This partnership is a perfect reflection of IGA's commitment to the joy of eating better which encourages Quebecers to eat healthier, choose local products, discover new flavours, and cook more.
Excellent. I have an association system of colours, too. In fact, after more than a decade of this stuff, it's really time I am honest with you. I am an expert. I have all the qualifications. First, you don't need any qualifications. That's me. Next, I can spot most of the more attractive great simplicities when they are in the room. They don't call me McSimple for McNothing. Also, I am cheaper than the next guy. Not cheap. Just cheaper. Finally, I am discrete. You will hardly know I am there and, in fact, as I represent no one other than myself so you know that the advice I offer will be without hardly any steering or strings. Topics you may care to retain my services for include: stemless glassware recommendations, faux history avoidance, menu preparation confirming pretty much anything largely goes with everything except when it doesn't, preventative hipster tips for the bouncer and inordinately detailed descriptions of the beers that aren't really available to you.
