The secret extraction technology of coffee and dripping coffee, how to judge the poor taste of 5g coffee if the extraction is wrong?
After the barista grasps the advantages and disadvantages of coffee by cup test, he will use various methods to adjust the most suitable extraction parameters, and use this as the basis to complete the ideal coffee.
Generally speaking, even if different beans are used, the coffee bean parameters currently used will be applied for extraction; when it is judged that there is a need to change, the particle size, extraction amount and other variables will be readjusted.
At such times,"not departing from the intended flavor range of the cup test" is far more important than "extracting the best coffee (Good Shot)". Because it is difficult to guarantee the best quality coffee at all times except at the competition site of the barista competition.
When setting the extraction parameters, you can use the various variables mentioned above for espresso and brewed coffee."The following provides several professional coffee site extraction parameter adjustment processes and settings tables for reference.
EI CAFE Coffee Roasters uses double the amount of ground coffee for espresso extraction. They extract coffee within a basic set of criteria, then adjust the variables according to flavor tonality to determine the final extraction parameters. Determining these extraction details is left to the discretion of the barista.
Under the condition that the weather does not change rapidly, the composition of raw beans does not change, and the comprehensive bean types are all the same, the error between the powder filling amount and the extraction amount and the basic parameters will only fall within 1~2g; the fineness will hardly exceed the basic set mesh number (Mesh) * of the bean grinder.
If the amount of powder and extraction differs from the basic settings by more than 5~ 10g, or the grinder scale needs to be adjusted to more than two spaces, check whether there is any abnormality in the roasting process, whether the espresso machine is malfunctioning, or whether the water purification filter is approaching the replacement time... And then find out the crux of the problem.
