Everyone knows that the normal coffee has different degree of dark color.We also know dark color of coffee will color our teeth but we can’t stop drinking.
Recently,Slovakian entrepreneur named David Nagy has developed clear coffee—a transparent coffee looks like water but it tastes completely like coffee.This coffee is design to appeal the consumers who want to keep their white because it does not color people’s teeth and it only has 2 calories.
Clear coffee is served cold and packaged in a 200ml PET bottle.It is loved and expected by many local consumers due to its magical coffee taste and convenience.
However,no matter how the coffee change,the material we sue is the same.Clear coffee is made of coffee bean and clear water.Therefor,any kind of delicious coffee is made of high quality coffee bean. Roasted coffee bean must be packaged in the coffee bag with WOJIN one way degassing valve to keep it’s flavor.Where there need roasted coffee,there need packaging and need WOJIN one way degassing valve.

When storing the coffee, we need to avoid light and heat, and keep it in a dry environment, we then need to use coffee packaging bags with coffee valves.
