Who doesn’t love a good cup of joe to kickstart the day? But let’s be real, brewing the perfect coffee at home can feel like rocket science sometimes. We reached out to six coffee pros to spill the beans on the biggest mistake folks make when brewing their morning brew. Spoiler alert: it’s not just about buying fancy beans! Once, I totally botched my coffee by using water that was way too hot—tasted like burnt toast. Check out these expert tips to avoid screwing up your next cup.


1. Using Water That’s Too Hot

Pouring boiling water straight onto your grounds is a rookie move. It scorches the coffee, making it taste bitter and kinda gross. Aim for water between 195-205°F to get that smooth, rich flavor without the burnt vibes.


2. Skimping on the Coffee Grounds

Don’t be stingy with your grounds, warns a head coffee roaster. Using too little coffee for the amount of water makes your brew weak and watery, like drinking brown sadness. A good rule is 2 tablespoons of grounds for every 6 ounces of water.


3. Grinding Beans Way Too Early

Grinding your beans days before brewing is a big no-no, according to a café owner. Freshly ground coffee loses its flavor fast, so grind right before you brew to keep those tasty aromas locked in.


4. Ignoring Your Brewer’s Cleanliness

A grimy coffee maker is a flavor killer, says a coffee blogger. Leftover oils and gunk build up and make your coffee taste funky. Clean your machine monthly with vinegar or a descaler to keep things fresh.


5. Using Crappy Water

Water quality matters, y’all, per a coffee consultant. Tap water with weird minerals or chlorine can mess up your brew’s taste. Use filtered water to let the coffee’s true flavors shine through.


6. Rushing the Brewing Proces

Patience is key, says another roaster. Rushing your pour-over or not letting your French press steep long enough leads to weak coffee. Take your time—let it brew for 3-4 minutes to get the full flavor punch.
