Can you imagine creating some sort of narrow focus on what you like in a coffee and then setting out on a quest for it. Can you imagine trying to teach someone to find a specific sort of taste? Might as well attempt to describe "blue" to a person who has never had sight (one of my very least favorite creative writing assignments when I was in school).
I would say he's starting out backwards, and doing it too academically.
" I looked into coffee and espresso and there's an incredible amount to study and SORT through.."
He makes it sound like a negative. What he seems to fear is what has kept me interested.
All I need is someone to help me zero in to find what I like from all the origins, blends, roast levels, brands etc.
"Hey! Sir Arthur! Do me a solid. Go out and find me a Grail."
Tell your friend, it's all about the quest and all that you meet along the way. Coffee, like life, is a journey, not a destination.
Tomorrow morning I will make a very nice espresso, drink it, and then I will tell your friend he really liked it. That will definitely save him even more trouble.
OK, maybe some (SOME!?) of that was a bit facetious (A BIT!?), but really, what is the point of taking a "class" and having someone teach you what flavors you like.. that's what it sounds like to me. Crops change, roasts change, and tastes change. I quit buying Sumatran a few years back because the earthy taste was getting to taste a bit too much like earth to me. ("HEY! This coffee tastes like dirt!".. "I know,. it was GROUND this morning."). So even if he does find some narrow range of something he likes, a year from now it could all change.
Is coffee-education designed obsolescence the new job security? Hmm.. I have a teaching credential and class starts promptly at 9:00!
