As in the style of SCA professional courses, the course is a long and articulated path with many practical phases.
· You start by analyzing with the Brew control chart cups prepared by changing the extraction parameters. The student must indicate how to modify them to obtain the desired result.
· It is tested how different extraction water temperatures affect the quality of the drink, and how preinfusion (so-called blooming) or turbulence affect the Brew Control Chart.
· The student will then be called to extract and measure with the Brew Control Chart beverages with a percentage of extraction of 16%, 20% and 24% while maintaining the same strength (ex 1.3%) and will have to best explain the different result in the cup.
· Three cups must be prepared with the same extraction percentage of 20% but with different strengths (1.15%, 1.35% and 1.45%)
· Using sieves (type Kruve) will be analyzed the impact of different measures of particulates for the extraction of coffee and the role of fines (under 400 microns) and Boulders (over 800 microns).
· We work on how to use the bypass technique to properly dilute the drink, a technique that is often used to extract large volumes of coffee or to speed up the extraction process.
· Water we measure with the new SCA Water Chart alkalinity, total hardness and Ph, to get a very precise picture of the water used and how it can affect the result in the cup .
*SCA suggests, to face this test, that you have already taken part in the SCA sensory intermediate level. It’s also required to have taken part in intermediate brewing at least three months before.
