Since its foundation, Quamar has always focused its efforts on product development. In recent years, the company has taken a step forward by acquiring technical-scientific equipment to accurately measure the particle size distribution through the analysis of ground coffee particles. Thanks to research and laser-controlled granulometry technology, significant progress has been made, allowing for the refinement of the entire range of coffee grinders. This has enabled the acquisition of skills to achieve the most uniform shape of ground coffee possible, thus ensuring optimal extraction control within a specific particle size class.
