10 steps for testing high-quality coffee

1. Prepare a little (about 10 grams) freshly roasted and immediately ground coffee in a small cup.

2. Smell it and see its dry fragrance.

3. Pour in the hot water of about 95 degrees Celsius. Do not boil and immediately pour it into the coffee powder. Let it stand for about half a minute and then pour into the coffee powder after the temperature drops slightly.

4. Smell the aroma coming from the rising steam.

5. Leave the cup sample for three to five minutes and then stir with a long spoon.

6. Smell and evaluate the aroma and concentration of steam while stirring.

7. Pick up the coffee grounds floating on the surface and throw them away.

8. Scoop a tablespoon of coffee without residue into the mouth and sip it straight to the root of the tongue ~ feel the smell ~ don't swallow it in a hurry ~ let the coffee flow in the mouth and feel the consistency of the tongue ~ whether the taste is still strong before swallowing it into the throat.

9. Slide your tongue to the upper edge of the mouth to feel its texture and taste.

10. Stay in the mouth for three to five seconds and then spit it out. Whether the aftertaste remains or even turns sweet.
