Finally found and was explained what this thing is on my coffee bag, thanks. (Ecuadorian high altitude coffee, brand: montañes, like it becouse it's organic GMO free)
hi John, a rubber disk inside the valve will bend partially due to the pressure inside, thus allowing co2 to pass. it will be flat (closed) with a minimum pressure again to ensure nothing passes from the outside. kind regards, Arthur
@@EduardO-gm7hx why it's used is explained, but not how it works. The principal of operation is that you have a rubber disk held against the outside of the pack with a perforated cover. The perforated cover holds the disk against the bag, keeping it sealed. However when pressure inside of the bag is sufficient the disk is forced away and a small puff of gas is released until the pressure can no longer keep the opening. The disk once again seals the bag. The idea is that a small amount of positive pressure is always in the bag, so that no gas can ever enter, only escape.
As the video says, the intention is to vent excess CO2 so that the bag does not burst. And to also prevent oxygen from getting in. Coffee shouldn't be moist at all... If anything a regular opening would allow moisture in, causing the coffee to degrade faster and go stale.
What a pointless video! The one-way valve is there purely for the convenience of the manufacturer, otherwise the build up of carbon dioxide would burst the bag... then they couldn't sell it - duh. Unfortunately most of the precious 'notes' also escape through the valve together with that wonderful elusive aroma that is soon lost forever. To test this is true, leave a bag of freshly ground coffee in your car for a few hours with all the windows closed - then open the door and you will be shocked. The only way to enjoy a quality, full bodied cup of coffee (80% arabica & 20% robusta ideally) is to freshly roast and grind the beans then infuse with pure / low TDS water and consume immediately. That's it - there are no short cuts known to science!
I always thought it was made for customers to smell the coffee.. I feel stupid now
Well... not a stupid thought tho, 'cause I thougth the very same
Well, I will try the smell of the coffee from those holes, so never wondering why it is there. Good to know.

Thanks for the video. I didn't realize they use the valve bags for ground coffee too. I guess its not vacuum packed?
Thank you ❤️
And no explanation of how it actually works. Nice.

It literally explains how it works

Now I know. And knowing's half the battle.
No it’s for smelling the coffee to see how good it is or something idk
The more you know.
I asked, UA-cam delivered.
It's there to let excess moisture out of the bag
no it's not

I never was curious about this, but it makes total sense from a packaging perspective
