**FAQs about coffee**
1. **What is coffee?**
Coffee is a beverage made from roasted and ground seeds - often called beans - of different varieties of the coffee plant. It is known for its unique taste and its caffeine content, a natural stimulant.
2. **Where does coffee originally come from?**
Coffee originally comes from Ethiopia, where it was discovered in the 9th century. It spread across the Arabian Peninsula in the Middle Ages and finally reached Europe in the 17th century.

4. **How does caffeine affect the human body?**
Caffeine is a central nervous system stimulant. It can help reduce fatigue and improve alertness and focus. Caffeine works by blocking the effects of the neurotransmitter adenosine, which increases feelings of alertness.
5. **How do you prepare the perfect coffee?**
The perfect coffee brew can be very subjective and depends on personal preference. However, there are some general guidelines: use freshly roasted and ground beans, watch your coffee to water ratio (a general rule is 1 to 18), and make sure your water is the right temperature (between 90- 96 degrees Celsius).
6. **Is coffee healthy?**
Moderate coffee consumption can have a number of health benefits, including increased alertness, improved cognitive function, and reduced risk of some diseases, such as type 2 diabetes and Parkinson's. However, it's important to note that too much caffeine can cause side effects like trouble sleeping, nervousness, and increased blood pressure.
7. **What is Fair Trade Coffee?**
Fair Trade coffee is coffee produced by farmers who receive fair wages and work in an environment that respects both social and environmental standards.

8. **What is the difference between espresso and filter coffee?**
Espresso and filter coffee differ mainly in the preparation method. Espresso is brewed under high pressure, resulting in a strong, concentrated drink. Drip coffee is made by slowly filtering hot water through ground coffee, resulting in a lighter and larger beverage.
9. **What is Decaffeinated Coffee?**
Decaffeinated coffee is coffee from which most of the caffeine has been removed. The decaffeination process usually occurs before the beans are roasted. Decaffeinated coffee still contains a small amount of caffeine, but is a good option for those looking to reduce their caffeine intake.
