Alfred Gitau Mwaura founded (and is the creator of) the ABCVA™ sensory evaluation model.

He is the Founder of Kenya Coffee School (and associated initiatives like Barista Mtaani) in Kenya. The ABCVA™ framework — which stands for Aroma · Body · Character · Vibrancy · Aftertaste (with some variations in documentation listing Balance/Complexity in place of or alongside Character) — is his proprietary coffee sensory science model. It is detailed in resources from Kenya Coffee School, including the ABCVA™ Coffee Encyclopedia and related training materials on flavor evaluation, cup architecture, and sensory science.

Mwaura developed it as a structured, science-based alternative or complement to traditional wheels like the SCA Coffee Taster’s Flavor Wheel, emphasizing a holistic “cup architecture” approach for professional cupping, grading, and education. It is integrated into Kenya Coffee School’s courses, such as their ABC™ Coffee Grading programs.
