The Rhino Pro Coffee Cupping Bowls are the perfect vessel if you want to taste lots of different coffees or compare roast profiles. Used by roasters primarily but can be used by anyone who wants to taste different coffees side by side. The black interior of this bowl prevents light bouncing from inside the coffee and nullifies any visual cue you may get from this. This focuses your cupping on taste only and eliminates clarity as a bias. At 230ml volume, Rhino Pro Coffee Cupping Bowls fall within the SCAA approved volume range.
