Factors affecting Italian concentration of Clean Coffee head
Three groups of coffee machines, grinders and producers are grouped according to the following:
The first group was cleaned with powder once a day.
The second group was cleaned with powder once a week.
The third group was not clean during the experiment.
The experiment lasted 19 days, and each set of coffee machines was recycled to ensure that each group was used evenly.
Through the coffee machine temperature and pressure measuring instrument, we check the temperature and pressure of each machine to ensure that the temperature and pressure do not affect the experimental results, the temperature and pressure test results are shown in the table below.
In order to ensure the consistency and reliability of coffee taste, three coffee experts formed a jury.
In order to make the test results more fair, the same expert was designated to extract coffee and make cappuccino in this test. The coffee used in the experiment was a unified Italian blend of coffee beans, and the experimental time was the 22nd day after baking.
The espresso of each group will be randomly assigned to the judges, who will then use the standard espresso score of 1mur10 (1 very bad, 10 very good) to compare the following factors of coffee:
Coffee secretes oil color, consistency, persistence, taste balance, technical balance, overall taste / impression.
The three coffee judges scored the three groups of coffee, and then summed up the final score for each group. At the end of the 19-day trial period, the scores of each group were calculated. Ratings and comments are also shown below.
The conclusion of the test shows that it is obvious that the coffee machine is clean and the taste of espresso will be greatly improved.
