- Start by pouring hot water little by little slowly, in a circle, on the coffee grounds. Let the water soak and slowly add more water until you reach the desired volume.
- Wait for the water to brew the coffee to finish, and then pour the brewed coffee into a cup or pitcher.
French Press Brew Method:
- Heat the water to about 90-96 degrees Celsius.
- Put coarse coffee grounds into the French Press, with a common ratio of 1:15 (for example, 15 grams of coffee for 225 ml of water).

- Attach the top of the Moka Pot to the bottom and make sure it’s tight.

Negatives of coffee
Although coffee has many benefits and is enjoyed by many people around the world, there are some negatives to be aware of when it comes to coffee consumption. Here are some of the negatives associated with coffee:
Caffeine is a stimulant compound present in coffee. While caffeine can provide an energy boost and increase alertness, excessive consumption or sensitivity to caffeine can cause sleep disturbances, anxiety, irritability, or digestive upset. In more susceptible individuals, excessive coffee consumption may also cause irregular heartbeats or increase the risk of high blood pressure.
Addiction and withdrawal:
Regular and large amounts of coffee consumption can lead to physical dependence on caffeine. If someone who is dependent on coffee suddenly stops consuming it, they may experience withdrawal symptoms such as headaches, fatigue, mood disturbances, or difficulty concentrating.
Caffeine in coffee can affect the digestive system and trigger excess stomach acid. This can cause digestive disorders such as heartburn, increased stomach acid (GERD), or irritation of the digestive tract.
Caffeine in coffee can interact with some medications, including blood pressure lowering medications, sleeping pills, or pain relievers. These interactions can change the effects of the drug and affect a person’s health.
Additives and sugar content:
Some types of coffee sold commercially contain additives such as artificial sweeteners, added flavors, or preservatives. Consumption of coffee that contains added sugar can also increase the risk of obesity, diabetes or other health problems.
Stain on teeth:
Caffeine in coffee can cause stains on teeth if consumed in excess or if not followed by good oral hygiene. This can reduce dental esthetics and affect self-confidence.
