To make coffee with international standards, follow these steps..

1. Choose high-quality coffee beans: Start by selecting freshly roasted coffee beans. Look for beans that are sourced from reputable coffee-growing regions and have been recently roasted.

2. Grind the beans properly: Invest in a good-quality burr grinder to ensure consistent and even grinding. Grind the beans just before brewing to preserve the flavors and aromas.

3. Use the right coffee-to-water ratio: The generally recommended ratio is about 1:15, which means 1 gram of coffee for every 15 grams of water. Adjust the ratio according to your taste preference.

4. Control water temperature: The ideal water temperature for brewing coffee is between 195°F (90°C) and 205°F (96°C). Use a thermometer or an electric kettle with temperature control to achieve the right temperature.

5. Use clean, filtered water: Coffee is about 98% water, so using clean and filtered water is crucial to avoid any off-flavors. Tap water with unwanted impurities can affect the taste of your coffee.

6. Brew with the right technique: There are various brewing methods like pour-over, French press, AeroPress, espresso machine, etc. Follow the specific brewing instructions for your chosen method to ensure consistency and accuracy.

7. Pay attention to brewing time: Different coffee brewing methods have different brewing times. Over-extraction or under-extraction can affect the taste of your coffee. Follow the recommended brewing time for your chosen method.

8. Properly store your coffee: Proper storage is essential to preserve the freshness of your coffee beans. Store them in an airtight container in a cool and dark place. Avoid exposing them to moisture, sunlight, or oxygen.

9. Clean your brewing equipment: Regularly clean your coffee-making equipment, including the grinder, brewer, and any other accessories. Coffee oils and residue can build up over time and affect the flavor of your coffee.

10. Experiment and find your preferred taste: Coffee preferences can vary, so don't be afraid to experiment. Adjust the brewing variables like grind size, coffee-to-water ratio, or brewing time until you find your desired flavor profile.

11. Master the art of brewing techniques: Each brewing method requires a slightly different technique to extract the best flavors from the coffee. Invest time in mastering the technique that suits your preferred brewing method. For example, if you're using a pour-over method, learn the proper pouring technique and water flow rate to achieve optimal extraction.

12. Pay attention to the grind size: Grind size affects the overall flavor and extraction. Different brewing methods require different grind sizes. For instance, espresso requires a fine grind, while a French press needs a coarse grind. Experiment with grind sizes to find the perfect balance for your preferred brewing method.

13. Preheat your brewing equipment: Before brewing, preheat your coffee maker or equipment to ensure even extraction. This step prevents temperature fluctuations and helps in maintaining consistency throughout the brewing process.

14. Practice proper water distribution: When brewing with pour-over methods, make sure to distribute the water evenly over the coffee grounds. This helps in promoting uniform extraction and prevents over or under-extraction in specific areas.

15. Consider the coffee-to-water ratio for each brewing method: Different brewing methods have varying ideal coffee-to-water ratios. For instance, espresso typically follows a 1:2 ratio (1 part coffee to 2 parts water), while a French press usually requires a 1:15 ratio. Adjust the ratio according to the brewing method and your taste preference.

16. Keep an eye on the brew time: Depending on the brewing method, pay attention to the recommended brew time. Under-extraction results in weak and underdeveloped flavors, while over-extraction can lead to a bitter and unpleasant taste. Use a timer or follow brewing guidelines to ensure consistent results.

17. Experiment with water quality: Apart from using clean and filtered water, you can also experiment with different water profiles to enhance the flavor of your coffee. Some coffee enthusiasts prefer using mineral-rich water or even adding specific mineral salts to the brewing water.

18. Serve coffee in appropriate cups: Presentation also plays a role in coffee enjoyment. Serve your brewed coffee in clean and appropriate cups, such as a ceramic or glass cup. Ensure they are preheated for optimal temperature retention.

19. Train your palate: Developing a discerning palate is key to appreciating coffee at an international standard. Train your taste buds to recognize different flavors and aromas found in various coffee beans and brewing methods.

20. Stay updated with coffee trends: The coffee industry is constantly evolving, with new brewing techniques, equipment, and flavor profiles emerging. Stay informed about the latest trends, attend coffee workshops, and explore specialty coffee shops to expand your knowledge and refine your coffee-making skills.

By following these additional steps, you can further enhance your coffee-making skills and ensure that you're brewing coffee that meets international standards. Embrace the journey of discovering and enjoying the world of coffee.
