How the Perfect Grinder Can Make or Break Your Cup of Coffee
Many well-meaning coffee lovers kill the goodness locked within the coffee beans with the wrong type of grinder, one that should never have been designated for coffee.

In another post, I addressed how important the water is that you use to brew your coffee. Now we need to address the second most frequent way people murder their coffee beans: By using a blade grinder that’s really meant for pulverizing spices.
Only Grind Coffee with a Burr Grinder
Why not grind coffee with a blade, you ask? Because blade grinders result in uneven grinds. This is terrible for coffee, which must be evenly ground in order to have a balanced extraction (the process by which the water passes through the ground coffee and produces and “brews” the resulting cup of coffee).
Do yourself a favor, and relegate that blade grinder to your spice cabinet.
Coffee beans last much longer in their whole bean form (when kept away from oxygen). Once the coffee has been ground, we recommend brewing and consuming the coffee within one to two weeks. As whole beans, roasted coffee can remain fresh for 3 months, and sometimes even longer.
Which burr grinder do we recommend? We sell Baratza grinders in our store (you can get one online here) and their affordable Encore model is the best seller. But it depends on how you brew (you should invest in a more sensitive, higher quality grinder for an espresso machine, for example), your budget, your aesthetic, and so on.
If you would prefer to mix it up—using some coffee for French press, and some for pour over, then I recommend getting a burr grinder. Then you control when and how often you grind your beans and the way you will use them, depending on the brew method.
Bonus Tip: Don’t Refrigerate Your Coffee Beans!
Never store whole bean or ground coffee in the fridge. The refrigerator can cause condensation inside the bag or container of coffee, which will begin a brewing and degradation process. Coffee beans or ground coffee will be kept freshest when stored at room temperature either closed within the foil-lined bag it comes in, or inside a vacuum container made for coffee.
Essential Coffee Gear—Including a Favorite Grinder
Important: Boiling water is not a friend of coffee! Depending on your preference, you want water that’s between 195 and 202 degrees, and to control that temperature, you need one of these highly precise Bonavita kettles, which warm the water quickly and pour quite elegantly.

Scales: Not Just for Geeks
Okay, we know what you’re going to say: Seriously, a scale? I am not a coffee geek! Fair enough. But if you want to make better coffee, you need to know precisely how much coffee you’re using, and the Hario is going to tell you that, measuring beans to 0.1 grams. Trust us, within days of starting to do this, it’ll seem entirely natural, and the idea of using a scoop will sound ridiculous. Bonus: You can use it to measure things other than coffee, like artisan flour.

Easy Espresso: AeroPress
When it comes to roughing it, most of us draw the line at giving up morning coffee. Luckily, there’s the AeroPress, invented by the same entrepreneur behind the Aerobie, the magical flying disk. This innovative coffee maker has garnered thousands of rave reviews for its ability to brew perfect americano or espresso in 30 seconds. Easier and more reliable than a French press, it uses air pressure to press boiling water through coffee grounds and straight into your cup. Cleanup takes about a minute, and the durable pieces store neatly in a travel bag, making the AeroPress the perfect camping gadget to bring along for a cuppa.

The Virtuoso: La Marzocco Linea Mini
Used in many commercial contexts, the Ferrari of espresso machines boasts a dual boiler system for keeping the brew head and steam wand ready for action simultaneously. You’ll coax wonderful shots out of this unit, but like a Leica rangefinder camera or a vintage manual race car, it requires finesse to see top results. Isn’t that part of the goal?

A Smarter Sip
Smart technology comes to the teahouse with this mug that keeps your coffee consistently toasty warm at your desired temperature. Sitting with your drink for a spell? Keep your mug resting in the battery-powered base to ensure the warmth stays in check. Want to take it to go? The Ember comes in a travel mug version, powered by a portable battery (although it won’t stay warm for as long as the desktop version). Originally available in white, we love the matte black finish for its neo-noir vibe.
