Degassing valves are a game-changer in keeping coffee and other foods fresh. Learn why these one-way vents matter, what products need them, and how Savor Brands offers packaging that preserves quality—valve or no valve.
The Small Feature That Makes a Big Difference
When you think about what makes a great cup of coffee, you might picture fresh beans, the perfect grind, or water at just the right temp. But there's one behind-the-scenes hero that plays a key role before any of that: the packaging—and specifically, the degassing valve.
This small, one-way vent is the secret to keeping roasted coffee fresh while it sits on a shelf, ships across the country, or waits in your kitchen. But coffee isn’t the only product that benefits from it.
Let’s break it down.
What Is a Degassing Valve?
A degassing valve is a one-way vent built into flexible packaging. Its job? To let gases like carbon dioxide (CO₂) escape from inside the bag—without letting oxygen or moisture get in.
When coffee is freshly roasted, it releases CO₂ for days. Without a valve, this gas builds up, bloats the bag, and eventually causes it to burst or leak. But worse than the mess, without a valve, oxygen could sneak in—and that’s the real freshness killer.
Key Benefits of Degassing Valves:
Gas Out, Oxygen Out – Keeps the inside pressurized without ruining the seal.
No Bag Blowouts – Prevents bags from puffing up or exploding.
Longer Shelf Life – Less oxygen = longer-lasting flavor.
Keeps Coffee Tasting Like It Should – Protects delicate flavor oils from going stale.
Coffee Is Just the Start: Other Products That Benefit from Degassing Valves
Savor Brands understands that coffee isn’t the only thing that off-gasses or suffers from exposure to air. Here’s a breakdown of other foods and products that may need (or benefit from) degassing valves:
Snacks & Dry Goods
Granola
Cookies
Freeze-Dried Candies
Rice Crackers
Chips (Ulu, Taro, Sweet Potato, Shrimp, Wun Tun)
Some of these products are packaged while still warm from baking or frying, which can trap steam or gas inside. A valve helps release that pressure safely.
Sweets & Desserts
Butter Mochi
Cakes
Macarons & Macaroons
Pancake Mix
Specialty Hawaiian Chocolate
Desserts with sensitive textures can suffer from moisture buildup. Degassing valves allow for off-gassing while keeping humidity out.
Savory and Preserved Foods
Dry Spice Mixes
Beef Jerky Chips
Jam & Jelly
Pickled Vegetables
High-salt or fermented foods often continue to release gases. A valve is critical to avoid puffed or warped packaging.
Refrigerated & Frozen Items
Popsicles & Creamsicles
Ice Cream
Frozen Ulu
Even frozen goods can trap air during packing. Valves help maintain bag shape and seal over time.
Locally Grown or Organic Products
Teas
Organic Macadamia Nuts
Cacao Nibs
Tortillas
These items often rely on eco-friendly or small-batch processes that make precise packaging more important. Valves help preserve quality without added preservatives.

Ever wondered why there were slits and a little round plastic piece on your coffee bag? It's called a degassing valve and this little plastic piece plays a crucial role in your coffee packaging. Here's how it works: After roasting, coffee beans release carbon dioxide and this gas builds up inside a sealed bag. Without a degassing valve, the carbon dioxide build up can cause the bag to puff up or worse, burst in delivery transit. The degassing valve solves this problem by allowing the carbon dioxide to escape and preventing oxygen from entering. In short, the degassing plays a very crucial part to your coffee bags and will help with bursting that may occur during shipping.
