The coffee valve tells everyone that coffee contains 98% of the moisture.So the quality of water is very important for coffee.
Coffee should be made in fresh water, with minerals and oxygen, and the water should be medium or lower in hardness. If the hardness of water exceeds 10 degrees (dH), we recommend using a filter cartridge called CLARIS.
If possible, the carbonate hardness of the coffee-brewing water should be low, because carbonate hardness negatively affects the taste of the coffee and produces an insoluble carbonate precipitate. When this happens, it is recommended that CLARIS be used with a filter to remove most of the toxins and chlorinated compounds in the water.
When you or your customer have high requirement on the coffee kit, please also remember to have your coffee bean packed with a coffee valve without filter.
Brewing methods have different requirements on the powder thickness, exhaust valves without filter is suitable for whole-bean product that can be grinded at home.
Brewing method and the storage condition are both affecting coffee taste, and the exhaust valve with filter installed on package is suitable for powdery product.
We recommend you keep coffee beans in containers with one-way degassing valve, it helps to prevent quality change and to extend shelf life during ‘resting’.
