Today you will learn exactly how a coffee bolsacon valvula (bag with valve) operates to keep your brown gold fresh!
They were developed to solve a problem in
factories. You see freshly roasted coffee beans can emit co2 for up to 24 hours
after coming out of the roaster. When coffee was initial bagged into air tight
bags they would quickly refill with C02 and burst open. This was bad for the
coffee companies. They'd several orders returned and shop owners started looking
elsewhere for their coffee.
So the solution looks easy right? All you have
to do is let it sit out for twenty-four hours before packaging. Well if it were
that simple we would not have a bolsa para cafe (coffee bag) with valve today.
You see when coffee is exposed to open air it goes stale very quickly. Consumers
would hardly have their coffee a number of days before it became tasteless.
So, a smart people operating for a smart
company, developed a special bad that will let CO2 out without permitting
oxygen in! This was done by the use of a simple valve. As a result consumers
around the world rejoice as coffee fresh from the roaster is bagged into air tight packaging that keep
their wonderful coffee beans fresh.
