Components & Equipment
The quality of the components and equipment used to brew the coffee plays a key role as far as brewing is concerned. Be it the grinder, filter, or dripper, everything matters when it comes to brewing a cup of coffee.
Many people prefer a manual dripper as it filters sediment and oil. Under manual drippers also, a wide range of variety is available in the market. The same goes for grinders and filters. Hence, select the right equipment that can help you make a cup of coffee to suit your taste buds.
The taste and flavor of coffee are stored in the coffee beans. Coffee beans of different countries differ from each other in terms of aroma, taste, and flavor. The two most popular coffee beans are:
- Robusta beans are rich in chlorogenic acid and caffeine content.
- Arabica beans are known for their balancing flavors.
Be selective while purchasing the coffee beans. If you love having coffee, try looking beyond supermarket aisles. Specialty coffee might be a good change for your taste buds.
Roasting of beans is the step where beans tend to get their rich taste. Numerous methods can be used to roast the beans. The most suitable temperature for roasting is between 180-250 degrees Celsius. Duration for roasting is generally around 2-25minutes. Those fresh green coffee beans are transformed into flavorful, aromatic brown beans when roasted.
The aroma of coffee results from various chemical changes taking place in the beans during roasting. The quantity of aromatic compounds formed during roasting varies with the temperature and duration of roasting. For example, more roasting means less chlorogenic acids.
Type & Quality of Water
Pure water is not just essential for living but also for making good coffee. The taste of coffee made from tap water is quite different from that made up of distilled water. The reason being the distilled water is clean and free from impurities and other contaminants.
Recent studies have shown that hard water enhances the flavor of the coffee. Calcium and magnesium ions present in hard water are responsible for increasing the flavor.
Grinding & Brewing Perfect Coffee
Nothing can beat the taste of freshly ground coffee. The size and shape of the grounded beans play a vital role in giving aromatic smell and flavors to the coffee. Uniformly grounded beans tend to provide much better results. Many grinders are available in the market. Do thorough research before finalizing your purchase.
The brewing method used determines the taste of your coffee. You can select any of the brewing methods:
- Brief boiling
- French Press
The factors essential to get most from the coffee beans are
- Turbulence during brewing
The first thing that hits our senses when we hold a coffee mug is its addictive aroma. It is the aroma that compels us to taste it. If we leave the aroma aside, coffee is no more than a bitter, sour, and umami drink. The aromatic compounds are generated during the roasting process. Volatile compounds responsible for the aroma in coffee are released when coffee beans are roasted.
