Recently,we did an experiment to test the quality of our one way degassing valve. We used Belgian coffee pot to make coffee to get the answer. The coffee bean we used was stored in the aluminum foil bag with WOJIN one way degassing valve on March 28th,2015.The coffee’s flavor was the same as original though it has been stored in the bag over 5 months.The coffee was wonderful and all of us enjoyed it.We can taste such wonderful coffee due to WOJIN high quality one way degassing valve.WOJIN one way degassing valve can help coffee keep it’s freshness for a longer time than others .So all of the coffee we store in the office still in high quality.

We’ve ever used some coffee valves of other companies and placed them in the aluminum foil bags to store our coffee.As a result,they really let us down because their coffee valve is in a low quality.The coffee we’ve stored in the bag only for several weeks has lost it’s flavor and aroma due to the negative effect of the air entered the bag.The result shows that their coffee valve can’t help to fresh the coffee for a longer time.So the coffee actually shortens it’s life and causes the bitter and stale taste that customers hate.
