World Barista Champion's Hand Made Coffee Summary

Buy stale coffee beans.

Preservation is key to ensuring coffee beans are fresh, Erin said. Avoiding poor quality coffee is the first step to success. When buying coffee in some supermarkets, be sure to check the roast date on the package. Many supermarkets keep adequate stock on shelves resulting in coffee being stored past its freshness date.

II. Grinding into powder in advance

Do not pre-grind coffee if conditions permit. After coffee is ground into powder, coffee immediately begins to lose its aroma and other flavors.

Do not use unfiltered water

Erin strongly recommends installing qualified water purification equipment in coffee shops or homes to ensure that the quality of the coffee is excellent, even if the water supply in the city is not up to standard, even if there is a lot of pollution in the middle of transportation. With the above conditions, your coffee will taste better.

4. Water temperature when making coffee

Erin believes that most people extract coffee at too low a temperature, and if you keep brewing coffee with a hand brewer, you lose 10 degrees in the process. I would boil water from my kettle, or I would brew coffee using multiple pots during the process, keeping the same temperature for extraction, and these aromas and subtle fruity, floral, sweet notes would come out more at higher temperatures.

V. Abandonment

Erin: "When I get stuck, if I want the best cup brew, which I believe I can, I'll do it again." These mistakes are getting fewer and fewer,"and you can't give up groping anyway.
