Maybe the coffee bean after roasting by you,it is fresh and aroma.We can ensure that all the coffee are fresh after they have been roasted by all the roaster.
But how to keep the coffee fresh when they are on the shelf at the supper market? Or when they are one the coffee shop? Or when they are on the way to your clients' hands?
How to keep the coffee bean fresh,it seems not a very difficult question,maybe you will think that a good coffee bag that is ok. And maybe you also will think that a good coffee bag with zipper that is ok.
I agree with your thought,a high quality of coffee bag is one of the most important role for keeping the coffee fresh.But not enough.
As you can see,some bag of coffee ,have done the vacuum package.Yes,that also a good way to keep the coffee fresh,it have vacuum all the air outside the coffee bag.That also one of the good way to keep the coffee fresh.But how about the coffee aroma?
Why don't you try to install a coffee valve into your coffee bag?
First,the coffee valve not only can release the co2 outside the coffee bag,but also can keep the coffee aroma into your coffee bag.Why you can smell the coffee aroma through the holes on the bag? That is because of the coffee valve have the close pressure,while the inside co2 not enough their lowest value,they will stop releasing the co2 outside the coffee bag,and keep the coffee aroma in the bag.
So you can know whether a bag of coffee fresh,smell the coffee aroma through the coffee valve,I think that is the vacuum package can not do it.
