Where to Buy Coffee Beans If you're a big fan of whole beans the best place to purchase them is at your local coffee shop or roaster. If you're not fortunate enough to live near one, try searching online for companies which roast and ship to you. Geography plays a huge impact on how coffee tastes like therefore, pay attention to the origins of the beans you purchase. Arabica vs. Robusta There are more than 100 coffee species The two most commonly used are Coffea arabica and Coffea canephora (Robusta). hyperlink is more resistant to drought, pests, and diseases. It can be planted at lower elevations and produces more coffee cherries each year. It is also less expensive than arabica for cultivation. Robusta is responsible for 40 percent of all coffee that is produced around the world. While a poor quality batch may taste like burnt rubber, a superior brew using specialty beans can compete with Arabica's taste. The problem is there are a few exceptions, but the majority of the robusta available on the market comes only from plantations that are concerned about quantity. Robusta plants thrive at lower altitudes and their resistance to disease and pests is the result of the high amount of caffeine in the beans. It's this fact that makes Robustas a favorite option for traditional cafes and instant coffee. However, while certain companies advertise their product as 100% arabica, they often mix it with a variety of robusta to cut costs and provide their customers with an unsatisfactory cup of coffee. Robusta may have a harsher bitter, sour and more grainy taste than arabica. It also has the flavor of peanuts or nutty. Some people find these flavors unpleasant or overwhelming. Origin Coffee beans are actually seeds that grow inside small, vibrant fruit called coffee berries. When ripe, these berries are removed from the coffee plant and split into two beans. The beans are roasted, and then used to make our most-loved brew. Arabica is the most well-known variety of bean in the world. They are renowned for their soft, non-bitter flavor. They are also renowned for their richness, and they can offer an array of flavors. They are typically grown in Africa, Central America, and South America where the conditions are ideal for the production of high-quality coffee. They are more expensive than Robusta due to their growth requires more care. In order for the flavor profile to develop, they require specific temperatures and adequate rainfall. The top coffee beans in the entire world come from Africa. Many of the farms are family-owned and operated on a small scale. In addition to the region in which it is grown another crucial aspect to take into account when buying coffee is whether or not it's of single origin. “Single origin” could mean a range of things, but most often it means that the coffee is sourced from one farm, a crop or region within a particular country. This is an important part of what makes third wave coffee so appealing – knowing exactly where your coffee came from allows you to experience it in its purest form. Grind The quality of the coffee you drink is affected by the way it is prepared. You can find the perfect blend of coffee by playing around with different grind sizes and brew methods. The size of the grind can have a significant impact on the extraction of the soluble coffee solids from the ground. This impacts the flavor of the coffee. If the grind is too coarse it will be difficult for water to penetrate into the grounds to extract the soluble coffee solids. This is called under extraction, and could result in weak coffee. If the grind is fine, the water will pass through the grounds more quickly and suffer from an over extraction. This can lead to bitterness. You can purchase coffee that has been ground but it's recommended to purchase a whole bean and grind your own beans directly prior to making. This will keep your beans fresher and longer than if they were pre-ground. The burr grinder is the most popular to ensure a consistent grinding but you can also make use of a food processor, hand-grinders or a mortar and pestle. Burr grinders have two cutting discs that cut beans into a particular grind consistency by changing the distance between the burrs. A smaller gap will result in an easier grinding, whereas an increased gap produces the coarser grinding. Storage It is recommended to keep your bean bag tightly shut and only grind what you'll require for the next brew. You may also look into buying a resealable canister, which will remove air and allow the CO2 off-gassing that happens when the beans are first ground to be released. When stored properly, whole bean coffee can remain fresh for up to one month. Once your coffee is ground, its quality will begin to diminish in just 30 minutes. That is why it's best to only grind the amount you'll need and then store the rest of the beans in an airtight, clear container. There is a huge variety of attractive, easy-to-use coffee storage containers. Some are vacuum-sealed to keep moisture from getting inside. Some come with a one-way valve that lets out the gasses created by freshly roasted beans, which can prolong the freshness of beans. The best place to store the coffee you haven't used is in a dark, cool place with constant temperature. Avoid storing it in a cabinet next to your oven or stove, as the heat could accelerate the chemical reactions that destroy coffee. Keep the beans out of direct sunlight will cause the coffee to absorb and lose flavor.
