The world is filled with people who love
coffee and drink it every day. The coffee industry rakes in roughly $32 billion per
year today.
Because it's such a coveted product that has
to be made just right, the way that it's stored means a lot. Today, many bags
of coffee are outfitted with a special valve that helps with storage.
So what should you understand about these
valves? How can you compare bags of coffee with valves to those without?
Here are some tips you should know about
choosing the coffee bags that are best at preserving your goods.
Understand What the
Valve Is and How It Works
Seeing a coffee bag with a valve is quite
common in this day and age. You'll see this technology included on both coffee
bean bags and pouches for ground coffee.
These valves are circular and come with air
vents. They're typically found near the top or bottom of the coffee bag, where
they apply one-way pressure.
It's common to see these valves on different
types of coffee bags and brands in the grocery store. They are semi-permeable
and connected to the rest of the bag lining.
The Valve Helps to
Keep the Coffee Fresh
Freshness is the main factor at play with
coffee bag valves. It promotes the flow and release of gas so that the coffee
doesn't get stale while in storage.
These bags are often also lined with aluminum
material in order to preserve the freshness of the coffee. The valve prolongs
the shelf life of any coffee that you decide to buy.
People Say a Coffee
Bag With Valve Provides the Best Flavor
Coffee is a multi-billion dollar business,
which is why it's in every company's interests to protect the flavor of their
prized products. By focusing on coffee freshness during
storage, you're also helping to preserve the flavor.
Connoisseurs particularly appreciate bags
for coffee beans since it helps to keep them in their purest and most flavorful
form.
Since your coffee isn't getting oxidized, it's
also not aging. The fresher the coffee, the more robustness and aromatic
qualities you'll enjoy in every bag. Preserving the freshness also keeps the
little characteristics that bring out maximum flavor.
Letting Gas Leak Helps
With Coffee Storage
A coffee bag without a valve doesn't allow
carbon dioxide to escape the package.
After coffee is roasted during the production
process, it immediately begins expelling large amounts of carbon dioxide. If
freshly roasted beans or ground coffee were placed in a bag without
ventilation, the expelled carbon dioxide would keep expanding, possibly until
the bag exploded.
The smell and flavor qualities that we all
know and love about coffee also only happen once carbon dioxide is released.
The valves help to keep your coffee in its prime state by keeping the right
balance of gases.
Valves Allow the
Coffee to Retain Its Temperature
Your coffee also has to be stored at certain
temperatures to retain its qualities. The valves that get installed help the
coffee to stay at a cool room temperature, which is optimal.
It's best to keep your coffee bags out of the
refrigerator for this reason. Keeping the coffee in the pantry instead will
prevent moisture from overtaking the bag.
Manufacturers and
Packers Can Work Quickly Thanks to Valves
The valves also help manufacturers get their
products on store shelves and in your home quicker. Since the valve allows for
the expulsion of gases, packers and shippers don't have to wait for it to cool
off before packing.
This saved time adds up and allows them to
have the quickest and most efficient possible output. The uptick in production
is helpful both for the company's bottom line and the customer's
satisfaction.
It Helps You Keep
Contaminants Out of the Coffee
The coffee bag valve also acts as a safety
mechanism. When it's in place, your coffee is less likely to come in contact
with contaminants.
Keeping these contaminants out of the coffee
can prevent food poisoning and other problems. It also helps manufacturers to
avoid costly recalls that also hurt their brand.
Anyone concerned with the freshest, cleanest
coffee should always purchase bags with seals for this reason.
You Don't Need Valves
When the Coffee Is Canned
So what about canned coffee? Since these containers
are sealed airtight and don't have space for gas to escape, manufacturers get
the coffee to de-gas before packing them.
The tins are sealed airtight once the beans or
ground coffee has been given time to cool off. The tin is also made with an aluminum
inner lining, in addition to an aluminum-backed freshness seal at the
opening.
People often purchase tubs or tins of coffee
whenever they buy large amounts. You can still count on these products to be
fresh since the manufacturer handled the CO2 expulsion on the front end.
Choose the Best and
Freshest Coffee Bags
Coffee bags will provide the care that you
need for your coffee products. You likely have more of an appreciation of
coffee now that you understand some inside science behind how it arrives at
your kitchen.
Definitely check for that valve on your coffee
bag if you're the type of person who loves waking up to the perfect cup.
Coffee manufacturers prefer bags with valves for
the most part. If the product will be
used quickly, bags with no valve are more economically friendly.
When sealing your coffee bags, a constant heat
sealer will help keep your product fresher longer. Tin ties do not keep the air out as
efficiently as sealing your bag with a bag sealer. Constant heat sealers are the sealer of
choice for coffee companies, as they work best with the material the bags are
made with and give a consistent seal.
