Where to Buy Coffee Beans If you're a lover of whole beans, the best place to buy them is at your local coffee shop or roaster. If you're not close to a roaster, go online for companies that will roast and then ship your order. Geography plays a huge impact on how coffee tastes like, so pay attention to the origins of the beans you're purchasing. Arabica vs. Robusta There are more than 100 coffee varieties. The two most commonly used are Coffea arabica (Robusta) and Coffea Canephora. Robusta is more resistant to drought, diseases and pests. It can be grown at lower altitudes and produces more coffee cherries each year. It is also cheaper to cultivate than arabica. Robusta is responsible for 40% of all coffee produced around the world. While it's true that an inferior batch of robusta might taste like burnt rubber, a good coffee made with specialty beans can actually compete with Arabica in flavor. The problem is, with few exceptions, the majority of the robusta available on the market comes from plantations concerned about quantity. Robusta plants thrive at lower elevations, and their resistance to diseases and pests is the result of the high caffeine content in the beans. This is the reason why Robustas a popular choice for traditional diner and instant coffee. However, even though some companies might advertise their product as 100 arabica-based, they usually mix it with some type of robusta to cut costs and offer their customers the least desirable cup of coffee. Robusta may have a harsher sharp, bitter and more granular taste than arabica. It also has the flavor of peanut or nutty. These flavors may be unpleasant to some or too strong for others. Origin Coffee beans are actually seeds that are cultivated inside small vibrant fruits, referred to as coffee berries. When they reach their peak, the fruit are removed from the coffee plant, and then separated into two beans. The beans are then roasted before being used to make our beloved beverage. The most popular variety of beans are Arabica and are renowned for their smooth taste which isn't bitter. These beans are also renowned for their richness, and they can offer many different flavors. They are typically grown in Africa, Central America, and South America where the conditions are ideal for the production of top-quality coffee. These beans usually have an expense that is higher than Robusta, due to the fact that they require more attention in order to flourish. They need specific temperatures and a sufficient amount of rainfall to develop their flavor profile. The best coffee beans in the entire world come originate from Africa. Many of the farms are owned by families and run on a smaller scale. Apart from the region of production another crucial aspect to consider when purchasing coffee is whether or not it's single origin. “Single origin” could mean a range of things, but generally it means that the coffee comes from one farm, crop or region within a single country. Third wave coffee is good because you can experience it in its purest form, knowing exactly where it came from. Grind A great-quality brew begins with the best coffee beans, but the process of grinding, brewing and serving can alter the taste of your coffee. You can discover the perfect blend of coffee by experimenting with different grind sizes and brew techniques. The size of the grind plays an important factor in the way that the soluble coffee solids are extracted from the ground during brewing, and this impacts the taste of your coffee. If the grind is too coarse it is unable to penetrate the grounds to get the coffee's soluble solids out. This is known as under extraction and may result in a weak cup of coffee. If the grind is too fine, water is able to pass through the ground too quickly and undergoes an over extraction, resulting in bitterness. You can purchase pre-ground coffee but it is best to purchase whole beans and grind them yourself immediately before brewing. This will ensure that your beans are fresh and will last longer than if you were to purchase the pre-ground coffee. The burr grinding machine is ideal to ensure a consistent grinding however, you can make use of a food processor hand grinder or mortar and pestle. Burr grinders come with two cutting discs that can be adjusted to produce a specific consistency in the grind. A smaller gap leads to an easier grinding, whereas the larger gap results in the coarser grinding. Storage It is best to keep your bean bag tightly closed and only grind as much as you'll need for your next brew. You might want to invest in a resealable canister that will eliminate air and allow CO2 to escape after the beans are crushed. Whole bean coffee can remain in its best condition for up to a month if stored correctly. Once the coffee is ground, its quality will diminish in less than 30 minutes. 500g coffee beans is why it's recommended to only grind as much as you'll need, and then keep the remainder of your beans in an airtight, clear container. You can choose from a variety of attractive and convenient containers to store coffee. Some are vacuum sealed to stop moisture from getting inside. Some even have a one-way valve that releases the gases created by freshly roasted beans, which can prolong the beans' freshness. The best place to keep your unused coffee is a dark, cool place with constant temperature. Avoid placing your coffee in close proximity to your stove or oven since the heat can speed up chemical reactions that weaken the coffee. It is also important to keep the beans out of direct sunlight as they will absorb it and reduce their flavor.
