This actually reminded me of a friend of my father. This friend was a chef at some over-the-top fancy (or in my book, prissy) restaurants in his heyday. Anyway he pretty much lost the ability to just eat and enjoy food because he would constantly judge it. If I recall, he would generally just eat some bread and some cured meat for most of his meals. I honestly imagine he would jump over a chance to have Soylent. My thought on the matter is that if I ever get my head that far up my ass that I can't enjoy something that tastes good because of some stupid ideal of what something "should" be, well then I've seriously screwed myself over.
Are you claiming all espresso is burnt or chocolatey?
There's a lot that can go into making a good cup of coffee. New Zealand (where I'm from) has one of the higher coffee shops per capita in the world (mostly non chain) and you may be surprised how much a coffee can change from barista to barista even using the same beans in the same shop. If you're spending the money every day on that little moment of luxury you can notice the difference. (Whether or not it's suffering from the same biases in experience as expensive wine can I'll leave for someone else to speak on).
"But (nearly) everybody loves the Aeropress! It can't be comparable!"
I'd argue the Keurig's weak spot is not the brewing methodology, it's the coffee itself. The K-Cups are sealed with nitrogen and do their best to stay fresh, but no matter how many tricks you use to try and preserve the flavor of coffee that was ground three months before you brew it, it's going to take a massive quality hit -- and y weren't starting with beans that would bowl a coffee snob over in the first place. When I actually used the correct amount of fresh ground coffee from a good roaster, though, it produced a surprisingly good cup of coffee. And I've cut open a K-Cup and brewed the coffee within using a French Press; what came out tasted, well, a lot like what you'd expect out of a Keurig, just s slightly grittier.
(Then the pump broke and I bought a Chemex and lived happily ever after. The end.)
I use the Chemex when we have company over, it's the best combination of quantity and quality that I have found so far. As for one to two servings, I swear by the Kalita Wave[0]
I've heard good things about the Kalita Wave, but I'm not sure I want to add another coffee brewing device to the collection at this point. :)
