ASCA has a suite of judging talent that ensures our competitions are run to the highest standard in the world. As volunteers, they give up their time to help our competitors improve on their skills and prepare for the world stage.

We also encourage judges to sit for WCE-accreditation, to help contribute to the global coffee community.
