Coffee Brewing Equipment
Coffee brewing machines and brewing equipment come in many forms, models, and designs that have continued to evolve over time, particularly in regards to the specialty coffee /premium gourmet coffee industry which is always in search of a better cup of coffee and more convenience in producing it. The top ways to make coffee are:
When looking for some milder flavour we recommend Southern American such as Brazil and Colombian beans. Some brighter (more pronounced) coffees come from places like Costa Rica and Guatemala. Heading east we get more earthy tones from Kenya and Ethiopia, which produce some of the highest quality Arabica beans in the world, along with Tanzania. For flavors that tend towards spice and hold a great dark roast, we recommend Sulawesi and Sumatra.
Then you will be ready to get started in learning how to make coffee, real coffee and the best coffee you ever tasted.
Always store the coffee in a cool, dark and dry place, and not in the freezer or refrigerator. This is essential to prevent the fine flavors and aromas of the freshly-roasted coffee from degrading due to exposure to light and air.
Ideally, you want to store your coffee in a 1-way valve seal container such as the Friis Coffee Vault. If you have opened the coffee bag already, the worst place is the freezer because the coffee beans will absorb moisture. Unopened coffee bags with a 1-way valve seal may be stored in the freezer, and this can actually extend the freshness.
According to the SCAA, the optimal water temperature for coffee is 92 - 96C (197.6 - 204.8F) for 90% of the contact time.
In manual brewing method such as french presses and pour-overs, this can be achieved by bringing the water to a boil and letting sit for 3-5 minutes before adding it to the ground coffee.

How to Grind Coffee
Many prefer to grind and brew their own whole bean coffees. The best choice among coffee grinders, in regards to preserving the coffee beans' flavors and aromas, is a conical burr grinder.
The worst type of grinder to use is a blade grinder because they generate too much eat and can actually re-roast the coffee beans. Only grind what you are going to use at the time because once the coffee has been ground it will lose its fine flavors and aromas very rapidly.
The most important point is to use the correct grind for your coffee maker.
Avoid using too fine of a grind because it can break up the coffee bean fibers to much as it can cause the aromatic oils of the coffee to be over-exposed to oxygen and result in a distinct bitterness. Grinding too coarse will result in underextracted coffee, as the water will pass through too quickly.
The most common coffee methods for filtering brewed coffee is using filter paper though a metal screen filter or even a cloth filter may also be used.
The best brewing method is often deemed to be the French Press, which allows coffee grinds to soak directly in hot water.
With no paper filter to remove the coffee's volatile oils, the French Press allows the coffee connoisseur to enjoy all of the best qualities of a premium gourmet coffee including its body, aroma, acidity, aftertaste, bitterness, and sweetness.
A good French Press has a stainless steel or gold mesh filter. Make sure your equipment is perfectly clean because old residues can impart a tainted taste to your perfect cup of coffee. It's also important that the glass be made of borosilicate - the same material as beakers in science labs - to deal with the heat without shattering. Glass is a poor choice.
There's a number of different brands and models as well as sizes, ranging from 1-cup (30 mL) all the way up to 8.6 cup (1500 mL).
Automatic Drip Coffee Makers
Much more common in U.S. households than the French Press is an automatic drip coffee makers (autodrip coffee maker) that employs the filter-drip method of coffee brewing. Water is placed into the automatic drip machine which then heats the water and drains it onto a bed of roasted, ground coffee.
The water seeps through the coffee grounds, absorbing the coffee's flavor materials that give coffee its flavors and aromas. The coffee beverage then pass through a paper filter into a coffee pot.
Drip Filter Coffee
Drip filter coffee is also commonly made without a machine by simply pouring hot water over the roasted, ground coffee that is placed in a filter. The Filter Drip method is also called the Drip Filter Method, Drip Brewing, and Drip Coffee.
Brew Turbulence and Brewing Formula
The agitation of coffee grounds within the coffee bed during coffee brewing is known as the brew turbulence and is created by the rate of the water flow during brewing as well as the water's spray pattern and the configuration of the brew basket on the brewing equipment.
The ratio of water to coffee used to create the optimal coffee beverage strength from a particular type of coffee brewing equipment is known as the brewing formula.
European Coffee Preparation
The hand-preparation of coffee beans for brewing is known as European Preparation. This involves meticulously removing, by hand, any foreign matter (e.g., pebbles, twigs) as well as any imperfect or defective coffee beans.
See: Cold Brew Coffee
The Cold Water brewing method involves soaking the ground coffee in a relatively small amount of cold water for about fifteen hours, then using a filter to separate the grounds from the beverage using the drip method.
The Cold Water method produces strong, concentrated coffee, which is often stored for ready use, and may be mixed with hot water when desired. The resulting brew tends to be a low acid coffee and have a light body and while some say the coffee has a bland flavor, others describe it as a very pleasing, delicate taste.

Keurig created the K-Cup® for brewing various beverages including coffee (the coffee K-Cup), and it is now also referred to as K Cup Coffee, K Cups Coffee, K Coffee Cups, K-Cups Coffee, Coffee K Cups, Coffee KCups, and K Cups for coffee.
A K-Cup is a pre-packaged plastic container of coffee, tea or hot chocolate, and the K-Cup is designed for use with a Keurig single-cup brewing system that brews the beverage in less than one minute without any preparation or clean up required.
Anatomy of a K-Cup
The coffee K-Cup has a coffee filter inside, and ground coffee beans are sealed into the K-Cup plastic container with a tin foil lid. The coffee K-Cup is placed into the Keurig brewer which then brews the coffee by puncturing the foil lid as well as the bottom of the K-Cup and forcing hot water through the cup, and then the beverage flows into a mug.
Hundreds of options are offered in Keurig K-Cups including numerous flavors and blends of coffee as well as Fair Trade coffee, organic coffee, flavored coffee, and coffees from Ethiopia, Sumatra, Kenya, Brazil, Nicaragua, Costa Rica, Mexico, and Guatemala.
K-Cup Coffee Brewers
Keurig sells both home and commercial models of brewers. Some commercial models are plumbed-in and also automatically remove used K-Cups into a disposal receptacle.
Keurig sells five household models of K-Cup brewers: the Mini, Platinum, Special Edition, Elite, and Breville (made by Breville). There are also seven commercial models including the DeskPro, OfficePro, B140, B150, B155, B200, B3000SE.
Keurig also offers an environmentally-friendly re-usable filter called the My K-Cup which allows users to provide their own ground coffee.
