Ah, coffee…my favorite morning ritual and source of caffeine. (As co-author of The Complete Idiot’s Guide to Coffee & Tea and a frequent contributor to Fresh Cup Magazine, I’ve given coffee a good deal of thought.)
Brewing a great cup of coffee seems easy, but how often does yours taste like it does at a local coffee shop? (Never?) The good news is, unlike other culinary endeavors, making good coffee is more about technique than splurging on gadgets. A bold and delicious cup is attainable at home if you avoid these common mistakes. Don’t worry if you spill coffee on your carpet, we’ll show you how to get the stain out.

Mistake #1: Using Water that isn’t Hot Enough
Many commercial drip brewers never reach the ideal temperature (195 to 205 degrees) for perfect coffee. Water in this range extracts the most flavor from the beans. Switch to a French press or pour-over method (Chemex or a ceramic filter), where water just off a boil is poured over ground beans and steeped for three to four minutes. These generally cost around $30, which is cheaper than the average electric brewer.

Mistake #2: Using Beans that were Ground a long Time Ago
Buying pre-ground beans is a no-no. The minute coffee beans are ground, they start to release their nuanced flavors. The longer you wait to brew, the more the flavor will have diminished. Grind whole beans in the grocery aisle or do it yourself at home: Invest in a low-cost blade grinder or spring for a burr grinder for an even finer grind. Power it up while the water is heating up. (For bonus points, amp up the flavor by adding spices to your beans.)

Mistake #3: Pouring into a Cold Cup
Think about it. If you pour hot liquid into a container of a lower temperature, it won’t stay hot for long, right? Prolong your sipping pleasure by pre-warming the cup. The best part is that the water is already on its way to boiling-just pour some of the water into the cup, leave it in there while the coffee’s brewing, and empty it before filling with coffee. It’s also a good idea to rinse out your French press or pour-over with hot water before adding grounds. Organize your coffee pods with this quick trick.

Mistake #4: Drinking from the Wrong Kind of Cup
Those dainty china teacups you pull out for a tea party or the super-functional Corelle coffee cup you’ve had for years are going to drop in temperature quickly, leaving you with (gasp!) room-temperature joe. A thick-walled cup maintains the coffee’s steaming hot temperature for longer. Try to find a diner-style white coffee mug with a thick wall. We also like sipping from sturdy, handcrafted ceramic mugs.
Mistake #5: Using Stale Beans
This is getting into coffee geek territory…but again, who wants to drink subpar coffee? Ideally, you want to use beans that have been roasted within the last three weeks. The easiest way to ensure this is to know the roast date. Coffee roasters who sell their beans on site will often label the bags with this info. If you grab a bag of local beans at your grocer or farmers market, check the bottom of the package-they often stamp the date there. (In the meantime, want to up the flavor of a dull cup? Try dunking a cookie.)
Mistake #6: Eyeballing the Measurements
Spooning your recently roasted and carefully ground beans into the filter by eye is a habit you’ll want to break now. Measuring grounds allows you to control the strength of the cup. A good rule of thumb is to use eight heaping teaspoons for a 34-ounce French press (standard size). This will result in coffee that is bold and assertive—but not as strong as espresso.
Mistake #7: Not Upgrading your Sugar and Milk
How one takes his or her coffee is a matter of personal choice, but we always recommend trying to get the most flavor for your sip. Many coffee shops have those little brown packets of raw sugar (aka turbinado sugar). This sweetener simply tastes better than white sugar. In terms of milk, we like to splurge and use whole milk or half-and-half. Nonfat milk can water coffee down. Really want to indulge? Make one of our best-ever coffee cakes and have an amazing morning.
Mistake #8: Using an Incorrect Coffee-to-Water Ratio
Ever taste a cup of coffee and think, wow, that’s really weak? Perhaps there is too much water—or not enough coffee—for the proportion to work. Convention is to start with two heaping tablespoons of coffee per cup and then modify future brews if needed. Check out this other amazing use for coffee filters around your home.
Mistake #9: Skimping on Water Quality
It’s tempting to use tap water because it’s free and you just flick on the faucet, but you really will taste a difference when you switch to filtered water or bottled spring water. That’s because these elevated waters are free of minerals and are not acidic. Otherwise, tap water’s impurities will affect the taste of your morning brew. Did you know you can also use coffee filters for dusting? They work great!
Mistake #10: Storing your Coffee in the Wrong Place
There isn’t one right place to store coffee. But you do want to find a spot free of humidity. This can mean using a container with an air-tight lid (such as a mason jar) or storing a bag or can of coffee on a shelf or back of the pantry (and, nope, not your freezer: it’s humid in there).
