The one way degassing valve knows that in order to ensure the optimal solubility of the coffee, the boiling water temperature should be lower than boiling point. If the water temperature is too high, the taste of coffee will become bitter, but if it is too low, the taste of coffee will become sour, losing the aroma and flavor of coffee.
The barista's mastery of the coffee machine's performance keeps the water at the optimum temperature so that the coffee's aroma is released without reservation.
Of course, the barista must take the time to figure out the performance of the coffee machine.
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’.
