BREW & GRIND
Good coffee doesn't just happen. It's all about your water, your coffee, the grind you use, and the way you choose to brew it. Some could say it's a science, and maybe it is. Here's a few tips they we think will help you find your perfect cup at home.
The water you use is VERY important to the quality of your coffee. Use filtered or bottled water if your tap water is not good or imparts a strong odor or taste, such as chlorine. If you are using tap water let it run a few seconds before filling your coffee pot. Be sure to use cold water. Do not use distilled or softened water.
Use the proper amount of coffee for every six ounces of water that is actually brewed, remembering that some water is lost to evaporation in certain brewing methods. A general guideline is 1 to 2 tablespoons of ground coffee for every six ounces of water. This can be adjusted to suit individual taste preferences. Be sure to check the 'cup' lines on your brewer to see how they actually measure.
Your brewer should maintain a water temperature between 195 - 205 degrees Fahrenheit for optimal extraction. Colder water will result in flat, underextracted coffee while water that is too hot will also cause a loss of quality in the taste of the coffee. If you are brewing the coffee manually, let the water come to a full boil, but do not overboil. Turn off the heat source and allow the water to rest a minute before pouring it over the grounds.
The amount of time that the water is in contact with the coffee grounds is another important factor affecting the taste of your coffee. In a drip system, the contact time should be approximately 5 minutes. If you are making your coffee using a plunger pot, the contact time should be 2-4 minutes. Espresso, as the name implies, means that the brew time is short—the coffee is in contact with the water for only 20-30 seconds. If the taste of your coffee is not optimal, it is possible that you are either overextracting (the brew time is too long) or underextracting (the brew time is too short) your coffee. Experiment with the contact time until you can make a cup of coffee that suits your tastes perfectly.
Purchase coffee as soon after it has been roasted as possible. Fresh roasted coffee is essential to a superb cup of coffee. And purchase your coffee in small amounts—only as much as you can use in a given period of time. Ideally you should purchase your coffee fresh every 1-2 weeks.
The objective of a proper grind is to get the most flavor in a cup of coffee. How coarse or fine the coffee is ground depends on the method by which the coffee is to be brewed. Generally, the finer the grind the more quickly the coffee should be prepared. That is why coffee ground for use in an espresso machine is much finer than coffee which will be brewed in a drip system.
If you purchase whole bean coffee, always grind your beans as close to the brew time as possible. A burr or mill grinder is preferable because all of the coffee is ground to a consistent size. A blade grinder is less preferable because some coffee will be ground more finely than the rest. If you normally grind your coffee at home with a blade grinder, try having it ground at the store with a burr grinder. You may be surprised at the difference!
Do not underestimate the importance of the size of the grind to the taste of your coffee. If your coffee tastes bitter, it may be overextracted, or ground too fine. On the other hand, if your coffee tastes flat, it may be underextracted, meaning that your grind is too coarse. Tell the professionals where you purchase your coffee exactly how you will be brewing it. For example, will you be using a plunger pot? A flat drip filter? A cone drip filter? A gold mesh filter? They will grind it specifically for the preparation method you have chosen and the equipment you use.
Before using the coffee, try rubbing some of the grounds between your fingers so that you can 'feel' the grind and become acquainted with the differences in size.
Never reuse your coffee grounds. Once brewed, the desirable coffee flavors have been extracted and only the bitter undesirable ones are left.
Storage is integral to maintaining your coffee's freshness and flavor. It is important to keep it away from excessive air, moisture, heat, and light -- in that order -- in order to preserve its fresh-roast flavor as long as possible. Coffee beans are decorative and beautiful to look at but you will compromise the taste of your coffee if you store your beans in ornamental, glass canisters on your kitchen countertop. Doing so will cause them to become stale and your coffee will quickly lose its fresh flavor.
It is important not to refrigerate or freeze your daily supply of coffee because contact with moisture will cause it to deteriorate. Instead, store coffee in air-tight glass or ceramic containers and keep it in a convenient, but dark and cool, location. Remember that a cabinet near the oven is often too warm, as is a cabinet on an outside wall of your kitchen if it receives heat from a strong afternoon or summer sun.
The commercial coffee containers that you purchased your coffee in are generally not appropriate for long-term storage. Appropriate coffee storage canisters with an airtight seal are a worthwhile investment.
