About The Brand

Quamar is an Italian brand that specializes in manufacturing high-quality coffee grinders. The company was founded in 2000 and has since gained a reputation for producing precision grinders that are widely used in the coffee industry. One of the notable features of Quamar grinders is their burr sets. Quamar offers flat burr grinders, which are known for producing a uniform grind size. The burrs are made from hardened steel or titanium, depending on the specific model, to ensure long-lasting performance and optimal grinding results. While they may be pricier compared to some other brands, their reputation for quality and precision makes them a preferred choice for many coffee professionals and home baristas.
