Summary

This part of the standard establishes a method to determine the extraction yield and soluble solids of the coffee beverage, which has been called the direct contact method. This method is recommended to evaluate roasted and ground coffee with a coarse grinding degree corresponding to an effective particle size between 701 11m - 900 11m (see NTC 3534 and NTC 2441). For roasted and ground coffee with a medium grinding degree the drip method described in NTC 4602-1 is recommended.
