Geography plays a significant factor in the taste of coffee like, so pay attention to the source of the beans you're purchasing. www.coffeee.uk . Robusta There are more than 100 coffee varieties, but the two most frequently used are Coffea arabica and Coffea canephora (Robusta). Robusta is more resistant to diseases, drought and pests. It can be grown at lower elevations and produces more coffee cherries per year. It is also less expensive than arabica to grow. Robusta is responsible for 40% of the world's coffee production. While it's true that a subpar robusta batch can taste like burnt rubber, a premium coffee made with specific beans can easily compete with Arabica in taste. The issue is that there are some exceptions, however, the majority of the robusta available on the market comes from plantations that are concerned about quantity. Robusta plants thrive at lower elevations and their resistance to disease and pests is because of the high caffeine content in the beans. This is what makes Robusta a popular choice for traditional diner and instant coffee. Even though some companies advertise their coffee as being 100 percent arabica, they often mix it with a sort of robusta in order to save money, but provide their customers with a lower quality cup of coffee. Robusta may have a harsher bitter, sour and more grainy taste than arabica. It can also have an nutty, peanut or dark chocolate flavor. Some people find these flavors unpleasant or overpowering. Origin Coffee beans are actually seeds that grow inside tiny, vibrant fruits called coffee berries. These berries are removed from the coffee plant at the time they are ripe and then split into two beans. The beans are then roasted before being then used to make our favorite coffee brew. The most sought-after variety of beans are Arabica, and they're known for their smooth flavor that doesn't taste bitter. These beans are also regarded for their richness and capacity to offer a variety flavors. The main growing regions for these beans are Africa, Central America and South America, where the conditions for the production of high-quality coffee are perfect. These beans typically have more expensive prices than Robusta due to the fact that they require more attention to ensure their growth. They require certain temperatures and sufficient rainfall to establish their flavor profile. In reality, the best coffee beans originate from Africa in the region where a lot of coffee farms are owned by family-owned farms that operate on a micro-scale. When purchasing coffee, it's important to determine if the coffee is of single origin or not. “Single Origin” can mean many things, but it most commonly indicates that the coffee is from only one farm, or region within the country. Third wave coffee is great because you can taste it in the most pure form by knowing where it originated from. Grind A high-quality brew starts with the finest coffee beans, but the process of grinding, brewing and serving can alter the flavor of your cup. Making a variety of grind sizes and brew methods will help you discover the best blend of beans that suits your individual taste. The size of the grind has a major impact on the extraction of soluble coffee solids from the ground. This affects the flavor of the coffee. If the grind is too fine, water cannot penetrate the ground and extract the soluble coffee solids. This is known as under extraction and can lead to weak coffee. If the grind is too fine, the water goes through the coffee too quickly and undergoes an over extraction, resulting in bitterness. It is possible to purchase pre-ground coffee but it is recommended to purchase whole beans and grind them yourself before making. This will keep your beans fresher and longer than if they were pre-ground. A burr grinder is the most popular tool for creating a consistent grind. However, you can also use a hand-grinder, a food processor or a mortar and pestle. The burr grinder is equipped with two cutting discs which can be adjusted to ensure a particular grind consistency. A smaller gap produces an easier grind, while an increased gap creates a coarser grind. Stores It is recommended to keep your coffee bag tightly closed and only grind the amount you'll need for the next coffee. You may also think about purchasing a resealable container, which will block out air and allow the CO2 off-gassing that happens when the beans are first ground to escape. Whole bean coffee will stay at its freshest for up to a month if stored properly. However, once ground the quality of your coffee will decrease in just 30 minutes. This is the reason it's important to only grind as much as you'll need and then store the rest of the beans in an airtight, opaque container. You can pick from a range of attractive and convenient containers for storing coffee. Some of them are even vacuum-sealed, which stops moisture from getting in. Some have a one-way valve that will release the gases produced by freshly roasted coffee which will extend the freshness of the beans. The best storage space for your unopened coffee is in a cool, dark space that is at a constant temperature. Avoid keeping your coffee near your stove or the oven as the heat can speed up chemical reactions that degrade the coffee. Keep the beans out of direct sunlight will cause the beans to absorb the caffeine and lose its flavor.
