Burled Walnut Knockbox

Handcrafted from burled walnut veneer and stainless steel, these knockboxes from Café Kultur in Germany are unrivalled in terms of aesthetics, function and quality.

The exterior of the knockbox is handcrafted from burled walnut veneer mounted on hardwood. The veneer is sliced from Persian walnut burl (Juglans regia), considered one of the most valuable veneers and highly prized by cabinet makers, prestige car manufacturers and musical instrument makers. Native to southeast Europe and southwest and central Asia, the Persian walnut is hard, dense, tight-grained and polishes to a very smooth finish. The color ranges from creamy white in the sapwood to a dark chocolate color in the heartwood. Café Kultur purchases the burled walnut from a German timber broker that sources its wood from responsibly managed forests and is certified by the Forestry Stewardship Council (FSC).

The interior of the knockbox is manufactured by Rieber GmbH & Co. of Germany from premium food-safe stainless steel. Rieber is one of the leading suppliers of kitchen technology for professional gastronomy operations and private households, and supplies customers such as Bosch, BMW, Deutsche Telekom, and Gaggenau.

The knockbox is designed with "triple suspension" to reduce the shock, vibration and noise from knocking an espresso puck out of the portafilter. A layer of dense foam is sandwiched between the stainless steel interior and the burled walnut exterior, the knockbox has dense foam padding on the bottom (also reduces slippage), and the bar is spring mounted and rubber coated.

We are able to obtain a limited quantity of these beauties as the exclusive North American reseller. A must have for the espresso connoisseur.
