How much coffee beans does one cup need to be prepared And what is its caffeine content?

- Drip Coffee: Generally, a level tablespoon (or about 10-12 grams) of coffee grounds is used for every 6 ounces of water.

- French Press: Because the French press uses a steeping method, it typically requires more coffee. Approximately 2 tablespoons (or 15-18 grams) of coffee grounds are recommended for every 8 ounces of water.

- Espresso: Espresso involves a concentrated brewing process. For a single shot of espresso, about 7-8 grams of finely-ground coffee are used.

- Pour-Over Coffee: Similar to drip coffee, pour-over brewing typically requires 2 tablespoons (or around 12-15 grams) of coffee grounds per 6 ounces of water.

Caffeine Content in One Cup of Coffee:

- The amount of caffeine in a cup of coffee can vary depending on several factors, including the type of coffee beans, brewing method, and serving size.

- Generally, a standard 8-ounce cup of drip coffee contains about 95-165 milligrams of caffeine.

- Espresso, due to its concentrated nature, tends to have a higher caffeine content. One shot of espresso can contain around 63-90 milligrams of caffeine.

- Decaf coffee, while reduced in caffeine, can still contain a small amount. A cup of decaf coffee may have around 2-5 milligrams of caffeine.

Please note that these are approximate figures, and the actual amount of caffeine in coffee can vary among different brands and origins of coffee beans.
