The Ceramill De Luxe spice mill is great design combining WMFs Cromargan stainless steel and their own glass. This mill comes empty and can be filled with any spices or herbs.The clever aroma protection lid sits tightly on the De Luxe spice mill and not only protects the grinder but preserves the spice flavour. The mill includes the WMF exclusive grinding mechanism made from high quality ceramic material, not plastic (which has a limited life cycle or steel, which is prone to corrosion). The ceramic mechanism is harder than steel and is non corrosive so grinding salt crystal is not problematic, it is also food neutral and abrasion free. The mills are easily refilled and the grinding level can be adjusted from coarse up to totally fine by using the inside adjustment wheel which allows the continuous adjustment of the grinding fineness. For cleaning purposes the mechanism can also be removed easily.WMF offers gourmets products that are as beautifully designed as they are functional. They can be found in kitchens and households all over the world and are known for their premium product quality and outstanding designs. This relentless focus on design is what has set them apart since they started in 1853.
