You can also buy "crappy" coffee and make it taste better just by dialing in how you make it. Watch a couple youtube videos, spend about an hour and a half practicing making cup after cup of coffee, and you can make pre-ground Folgers taste pleasant.

Most people aren't aware that they can practice cooking many times in a row and get noticeably better in a day. You can't make 25 roast dinners in a row, but you can make 25 omelettes, or 25 cups of coffee, and dramatically increase your proficiency. If you only practiced once a day, you would actually not get much better, and it would still take you 25 times as long.
