Coffee is one of the favorite drinks on the planet. Most coffee lovers start their day enjoying an aromatic and stimulating cup of coffee, it is a ritual.
This ancient drink has not only been studied for its health benefits, food scientists have also taken on the task of identifying the key points to consider for get a perfect cup of coffee. There are five basic things that you should always keep in mind.
1. Choose the right grains
There are two main types of coffee species, Arabica and Robusta. Arabica is a coffee with a smooth and tasty flavor. Robusta has low acidity and high bitterness.
Arabica is more expensive to grow because the Arabica plant is sensitive to the environment and requires constant shade, humidity and temperatures.
2. Roast matters
Roast also plays an important role in the taste of coffee. The lighter the roast, the lighter the color and the higher its acidity. Dark roasts make the coffee low in acidity and have a bitter roast flavor.
Too high a roast will increase the bitterness, although there will be more complex flavors. “A medium roast is a good place to start with a good balance and a bittersweet finish,” says food scientist Makenzie Bryson Jackson to Well + Good. Jackson recommends trying a variety of toasts to find what suits your palate best.
As for caffeine, lighter roasts have a slightly higher concentration.
Preferably use beans that have been roasted in the last three weeks, suggests Kristine Hansen, co-author of The Complete Idiot’s Guide to Coffee & Tea.
3. Store correctly
Store your coffee in an airtight container in a place without moisture and without exposure to light to prevent your coffee from going stale.
4. Grind properly
The beans should not be ground too long before preparation, this alters the flavor, since it has exposed a greater surface of the bean to oxygen. The more time passes the more it will have decreased.
It’s best to grind it while the water is heating up, but if you don’t have a coffee grinder at home, grind the beans at the store. Ground coffee is best within two weeks of opening.
5. Water temperature
The water should not be too hot or too cold. “If the water is over 205 degrees, the coffee will be prone to being over-extracted and will be bitter and harsh. If it is below 195 degrees, it will be more difficult to remove, leaving you with a bitter coffee without volume“Says Jackson.
The hardness of the water also affects the taste of the coffee; harder water has more minerals. If you are a perfectionist, experts use distilled water.
Lastly, when you add too much coffee you can get more sour flavors. If you want a stronger coffee, instead of adding more beans, buy a lighter roast. A suggested measure for your coffee is 2 tablespoons of coffee for every 6 ounces of water.
