Coffee is like pizza: All of it is good, even though most of it is terrible, and only a little bit of it is truly amazing. The thing is, making killer coffee is reeeeeallllly easy.
Step 1: Buy good coffee
If it doesn't have a roast date on the bag, it's not good coffee. You've got less than a month from the roast date to drink it. (~$15)
Step 2: Get a burr grinder.
The cheapest good electric burr grinder you can get is Baratza's Encore, which starts at $130 new, but can be had for around $100 refurbished from Baratza. (If it's not there, check back every Thursday.) It's expensive, but I actually could not find a single pro barista to recommend a cheaper electric grinder; it doesn't exist.
Alternatively: Hario's Skerton hand grinder is just under $40. ($40-$100)
Step 3: Get a scale.
It sounds insane, and friends will make jokes about how you look like a drug dealer (lololol), but it's actually less annoying than measuring by volume. Also it's more precise: Coffee beans have irregular shapes, and the volume of water changes when it's basically boiling. And making good coffee is largely about consistency. Grams are your friends. (~$20)
Step 4: Get a Clever dripper.
It's called a Clever dripper, and it is perhaps the most hassle-free, foolproof way to make coffee ever invented. (~$20)
