FINALLY! A topic for me! 😁
Two of the most important things for the best cup of coffee:
1) Use GOOD water. Your coffee coming out is only as good as your water going in. Filtered coffee is a good step. Something that still has a little minerals in it is great. Reverse Osmosis water is BEST! Not a fan. But use good bottled water if you can get a hold of anything else.
2) FRESH ROASTED AND FRESH GROUND! Stay away from grocery store coffee. It's mostly likey been sitting on the shelf for months since it's been roster. Explore your local coffee roasters and find something you like. Best recommendation is having a burr grinder and grind EVERY time you want to brew your coffee. The more time your coffee has been 'exposed' to air after it's been ground the more stale it gets.
Just those 2 steps will GREATLY increase your coffee quality experience.
Lastly, enjoying coffee is like growing a beard. The only ones doing it wrong are the ones telling you you are doing it wrong!
