Coffee grounds are not expensive things, but they are not cheap either. This means you want to keep your coffee grounds fresh for as long as possible when you buy some. 

To prolong your ground coffee’s freshness, start by sealing the coffee in an airtight container, and add in some silica to remove moisture. Then keep them in a freezer instead of a refrigerator. The best way to keep your coffee fresh is to invest in a grinder and grind your coffee right before brewing.

This article discusses how to keep coffee grounds fresh for long periods of time and also considers how long coffee grounds can stay fresh. 

How Long Before Coffee Grounds Go Stale?

Coffee grounds stay fresh for a week or two before going stale. The factors that may influence how fast coffee grounds go stale may be sunlight, moisture, temperature, oxygen exposure, and the fineness of the grounds. 

Coffee grounds smell divine when you first grind them down. However, when it is done, you are essentially racing against time to consume them because they start to lose freshness from that point onwards. 

Coffee grounds stay fresh for a week or two before going stale. The speed and the time you have, before they turn stale, may depend on many factors:

Sunlight: sunlight may speed up the pace of your coffee grounds going stale. This means you want to keep your grounds away from the sun as much as possible. 

Moisture: Moisture can also speed up the breakdown of your coffee grounds. If you want your coffee grounds to stay fresh, keep them in a dry place. 

Temperature: If your coffee grounds are exposed to cold temperatures, such as in a freezer, they may last longer than if you leave them in the fridge or the pantry.

Oxygen Exposure: Because of oxidation, coffee grounds lose flavor when they come into contact with oxygen. The more oxygen they get exposed to, the faster they go stale. 

Ground Fineness: The finer the coffee ground, the faster it goes stale. This is because more surface of the coffee ground is in contact with the air, moisture, etc.

How To Keep Coffee Grounds Fresh For Long?

To keep coffee grounds fresh for a long, start by packing them in airtight packaging with moisture and oxygen remover. Store the ground in a freezer. If you are frequently brewing, store it in an airtight container, and keep it away from the sun. Consider buying beans and grinding the coffee before brewing for maximum freshness.

Store In Airtight Container

Start by keeping your coffee grounds in an airtight container. The container can be made of glass, plastic, metal, or anything else, as long as they seal airtight.

A lot of the coffee you buy should come with good airtight packaging that can be resealed after opening, so go ahead and use that. You can store the whole packaging in another airtight container for double protection. 

Add In Some Moisture And Oxygen Remover

Before closing the lid, throw in a couple of moisture and oxygen remover packs. This is because moisture and oxygen will remove the freshness and flavor of your beans much faster. 

For moisture remover, consider getting some sticks of food-grade silica gel crystals. For oxygen remover, you can also order small packets of food-grade oxygen absorbers. They are not expensive and widely available.  

Store In A Freezer, Not A Fridge

Once you have closed the lid of your airtight container, you store them in a freezer. This assumes that you do not plan to consume the ground regularly and have longer-term storage in mind. 

This is because the freezer has a lower temperature and may be drier than the refrigerator. Lower temperature and humidity should help preserve the freshness of your coffee grounds.

Keep In Pantry If Brewing Regularly

If you plan to brew coffee regularly with the grounds, then you may want to keep the grounds in the pantry instead. This allows you easy access to the coffee, making brewing faster. 

The same principles apply: keep them in an airtight container, in a dry place, away from the sun to keep them fresh as long as possible. 

Get Beans Instead Of Grounds

Another option you can consider is to get coffee beans instead of ground. This is because coffee beans stay fresh longer than coffee grounds, sometimes double the time.

The theory is simple. Beans have less exposed surface to the air, which means they lose flavor and freshness slower than coffee grounds. 

However, if you opt for this, you must invest in a grinder. Fortunately, they are inexpensive and can be easily maintained and cleaned. Get one yourself, and grind your beans before brewing for maximum freshness.

Drink Up The Coffee, Don’t Wait

This may sound very simple, but many many do not do it. If you have spent money on coffee, brew it and consume it regularly. Coffee ages like milk, not wine. There is no point trying to keep your coffee on the shelf for a long time only to watch it go stale. 

Plus, all the steps above may help keep your coffee grounds fresher for longer. However, you are still playing a losing game, as you will eventually lose the freshness and flavor after some time. This means you should brew and drink your coffee as soon as possible.
