The biggest problem is that really good coffee ruins bad coffee foreger. After making my own for so long, traveling and dealing with gas station or hotel breakfast coffee is especially jarring. Sometimes I wish I could forget how good coffee could taste.
McDonalds has surprisingly “good” coffee in this regard.
—do you have tips on how to actually brew it in a home setting? Or this is something can only be achieved by brewing large batches of the stuff, keeping it warm somehow, and letting it go stale for a few hours?
I think -actually- serving crappy diner coffee in Melbourne might be considered a hate crime against our culture though lol.
Third wave fancy coffee I make at home in our Chemex or Technivorm or get in really really good shops, as you describe.
McDonald's, gas station, donut shop coffee. It's swill but you confectionize it with cream and sugar. Double double as we say up here. It's not good, but it it's a utility. You just don't expect much from it, and that's fine
The problem coffee is the stuff in-between. Stuff that pretends to be specialty coffee, overroasted, overpriced ... but not actually good. Starbucks or restaurant espresso. Grocery store whole bean coffees that markets itself in a nice bag but turns out to be stale oily overroasted mediocrity. Simultaneously expensive, raises your expectations... and then just turns out to be junk.
You hit the nail on the head with this one. Disappointment tastes so much worse than the humble donut shop coffee.
but dark roasting can also cover up faults (especially around freshness, etc), and masks the more complex berry notes in beans if not done well
I find the good stuff to basically be a totally different category of drink, I think is what helps. Most coffee is pretty much just "coffee flavored" with just a little variation. The good stuff... it sits somewhere between coffee and tea, often has surprisingly little "coffee flavor", and delivers all kinds of interesting and delicate notes.
Like if you ask me "where can I get some good coffee around here" I've got recommendations, but if you follow up with "no, I mean good coffee" I'm going to have a different set of recommendations. Good coffee is a separate category of drink, LOL.
