Find out how water quality and grinding size impact the extraction process. Ultimately, the perfect cup of coffee is the one you enjoy the most!

Key insights

🌱Coffee beans come from coffee plants, not legume plants, despite their name.

🌍Different coffee beans have different chemical compositions, resulting in varying flavor profiles.

💧Water temperature plays a crucial role in coffee extraction, affecting the taste of the final brew.

🔍Grinding size determines the surface area of the coffee grounds and impacts the extraction process.

👨‍🔬Experimentation with different brewing methods and variables can lead to your perfect cup of coffee.

Q&A

Do different coffee beans taste different?

Yes, different coffee beans have varying chemical compositions, resulting in distinct flavor profiles.

Does the roast level affect the caffeine content?

No, the caffeine content remains relatively unchanged between light and dark roasts.

Do lighter roasts have more caffeine than darker roasts?

No, the caffeine content in coffee beans is not significantly affected by the roast level.

Does water quality matter when brewing coffee?

Yes, water quality, including mineral content, can impact the flavor of the final brew.

What is the best brewing method for a milder cup of coffee?

Infusion methods, like pour-over, tend to result in a milder and less harsh cup of coffee.
