The following general rules apply to each coffee making process discussed.
Coffee should be brewed for 4.5-5 minutes using a ratio of 55 grams (about 2 tablespoons per 6 oz of water) of ground coffee per liter of filtered water (195-205°F). We recommend filtered water or spring water as tap water frequently adds off flavours to the coffee and some minerals are essential to coffee flavor. We do not recommend distilled water for brewing coffee as it lacks the minerals to bring out the natural flavors of the coffee.
Methods of Making Coffee
French Press: The best way to control the time and temperature is to use a French press coffee maker. The French press offers unparalleled flavor due to perfect extraction time and delivery of the volatile oils that are often trapped in paper filters. A French press is also the least expensive coffee brewer available. To make coffee in a French press: boil the correct amount of water, pour some into the glass to warm the carafe for a minute or two. Freshly grind the coffee beans using a course setting, remove the plunger, place the coffee grounds at the bottom of the glass, add the hot water, stir by shaking, and after 4-5 minutes press the plunger down to separate the grounds from the extracted coffee. Note: You do not want to pour boiling water directly onto the coffee. The goal is to brew coffee at a temperature between 195-205°F.
Automatic Drip Coffee Maker: The easiest way to brew coffee is by using an automatic drip coffee brewer. Unfortunately, few coffee machines brew at the right temperature for the correct amount of time. The best drip coffee makers currently available are produced by Techni Vorm with the insulated carafe is probably the best drip brewer available on the market.
If your brewer has a hot plate under a glass carafe, remove the carafe after the coffee is fully brewed to prevent the coffee from burning. An insulated carafe is the best way to keep coffee hot because allowing a pot of coffee to sit on a hot plate only burns the coffee.
