1.Power thickness: the pressure pot is not too demanding on the coffee beans, but on the power thickness:
(1)Fine coffee powder will be extracted more thoroughly, so the taste will be more intense. But it can lead to poor filtration and to bitter coffee.
(2)Coarse ground coffee will reduce the burning smell when the extraction of roasted coffee beans, but also to cover a lot of the flavor of the coffee itself.
2.The temperature of water: High temperature water extracts quickly, but coffee is bitter, low temperature water extracts slowly, coffee is a little sour, so the flavor can not be fully extracted. The best temperature of water is 85-95°C.

The one way degassing valve tells you that you want to control a good cup of coffee and you must control these three factors.
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’.
