COFFEE PREPARATION
Making great coffee is not rocket science, you just have to pay attention to a few details. Regardless of the preparation method you prefer (auto drip, French, vacuum brewer, cold Brew, etc) consider the following tips:
Buy whole bean coffee
Purchasing whole bean coffee helps preserve and protect the coffee from exposure to oxygen and other contaminants. This sustains, as much as possible, the coffee's natural oils, aroma, and flavor.
Store coffee in an air-tight container
A glass container with a rubber seal works best. Store coffee in a cool, dry place, preferably in the freezer. Coffee absorbs moisture and other odors, so regardless of where you store your beans, be sure that it's either kept in sealed glass container or, at the very least, a zip-lock bag. We ship our coffee in mylar zip-lock bags with a one-way gas valve that allows the beans to expel gases, but prevent contamination from oxygen and other environmental sources.
Grind the coffee just prior to brewing and use the proper grind level
The grind level is one of the single most important elements to making a "good" cup of coffee. Different coffee brewing methods require different grind levels. Use a coarse grind in a French press or cold brew system, and a bit finer grind for a vacuum pot. Grind even finer for automatic drip. Generally, coffee that is ground too fine produces a more bitter cup. Coffee that is ground too coarse produces will produce a watery cup.
Use fresh water
Always use fresh, cold water and avoid chemically treated water whenever possible. Also, use the right ratio of coffee to water. While tastes vary from person to person, a good rule of thumb is to use between 1 and 2 tablespoons of coffee for every 6 ounces of water. Too little coffee won't necessarily make a weaker brew...it'll most likely make a bitter brew. If your coffee is stronger than you like, you can always dilute it with a little hot water.
Brew at the proper temperature
Be sure to brew the coffee at or around 200 degrees F. This temperature is commonly referred to as "off-boil", or a notch below boiling temperature. To achieve this temperature when boiling the water, remove the kettle once the water has reached the boiling point and wait 30-60 seconds before pouring.
Drink the coffee when it's fresh
You can keep coffee warm on a burner or hotplate for only about 20 minutes before its flavor starts to turn and become bitter. Interestingly enough, Tasting coffee when it is cool, gives you the true essence of your cup of coffee, heat can mask some flavor characteristics. So if your cup of coffee taste good cool you know it is an excellent cup of Joe.
