The dosing ring helps the barista dose coffee grounds. Its conical-shaped walls mean it acts as a funnel, ensuring coffee grounds from the grinder fall accurately into the centre of the portafilter. This is a handy tool to assist filling the portafilter because it keeps waste to the minimum and ensures your coffee preparation area stays clean and free from coffee ground spillages. The Quamar dosing ring has a simple design and is ideal for ensuring precise dosing. Lightweight and easy to install. It’s fashioned from aluminium which is then coloured using anodising treatment. The process renders it corrosion resistant and ensures it’s reliable and extremely durable. Available in two colours: matt black and gloss copper brown. Diameter measurements: 58 mm.
