How To Open A Coffee Bag And Reseal It – 5 Things To Know

Are you wondering how to open a coffee bag and reseal it after you are done with the coffee? It turns out that the response depends on which type of packaging your coffee comes in and how you intend to reseal it after opening it. 

To help ensure that your coffee lasts as long as possible, keep reading to learn more about how to open a coffee bag and reseal it properly so that your coffee retains its freshness and aroma over time. 

How To Open A Coffee Bag Properly?

If you want your coffee beans to keep their freshness for weeks, you must learn how to open a coffee bag properly. Below, you will find detailed instructions on tearing apart a plastic coffee bag. 

  1. First, fold the top of the coffee bag down until it meets the seal in the middle of the bottom seam. 
  2. Tear through this seal from one side to the other. Do not cut or poke at this area with scissors! The airtightness is critical if you want your coffee beans to stay fresh for weeks and maintain their quality. 
  3. Once you have torn through this part of the seam, start working on opening up one side of the coffee bag like a present being unwrapped, and then pour out any unused ground coffee into an airtight glass jar or jar that seals tightly with its lid.  
  4. Place the coffee bag on top of another sealed coffee bag so that when you close them together, they create a tight seal (or use packing tape). 
  5. Make sure there are no large holes near the seal where air can enter and spoil your freshly roasted coffee beans or grounds. 
  6. Finally, store your newly purchased coffee bags in a cool place so they are not exposed to heat or humidity, making them lose flavor fast and potentially cause molding.

5 Things To Know About Coffee Bags 

If you are a coffeeholic, there are some things you need to know about coffee bags. What sets coffee bags apart from other packaging options is the extra care taken to ensure that the coffee within retains its full flavor upon consumption. 

Coffee beans lose their quality when exposed to air and light, but this risk is reduced by making sure coffee bags are airtight and placed in darkness. The moisture of the coffee beans will also be preserved if the bag is resealed after opening it. Freshly roasted coffee can be retained for up to six weeks if stored at room or below-upstairs refrigerator temperatures.

What Is The Function Of A Coffee Bag?

The function of a coffee bag is to keep your roasted fresh coffee tasting its best. The coffee bag is essential for several reasons:

  1. It helps keep the coffee beans’ quality.
  2. It keeps the roast fresh and gives the coffee longer shelf life.
  3. It allows for easy storage of coffee grounds.
  4. It protects the coffee from light and air.
  5. It maintains the freshly brewed coffee hot for more extended periods. 

What Exactly Is The Purpose Of The Hole In Coffee Bags?

Some branded coffee bags in the supermarket can have a hole, a vent, or a circle, and you might have pondered their purpose. These holes allow air to get out from the bag so it won’t explode when opened. 

However, instant coffee comes in sealed packages, so there’s no need for such features. For this reason, these holes are more familiar with ground coffees than pre-packaged coffees. 

If you’re buying pre-packaged coffee, you are probably familiar with the thought that most coffee bags have this hole. Nonetheless, you shouldn’t worry about this feature, as it has nothing to do with the freshness.

How Should A Coffee Bag Be Resealed After Being Opened?

How well do you know how to reseal a coffee bag? Don’t be alarmed; this is far less difficult than opening it. 

Once the bag has been opened, there are two options for resealing it: fold over the top and seal with tape or fold the top over, press closed and seal with your finger. 

Which option should you choose? You should pick whichever will work best for your particular situation, and remember that when in doubt, permanently seal with tape! 

If you’re not sure which alternative to use, fold over the top of the bag and seal it with tape, then open it again before sealing it again. Your hand should have enough warmth left from unsealing the bag to keep an excellent seal. 

If You Leave The Bag Open, Does Coffee Eventually Go Stale?

After being opened, roasted coffee beans will remain fresh for 1 to 3 weeks. Ground coffee keeps its freshness for up to two weeks after being opened. 

Roasted whole-bean coffee can last as long as three weeks. There are several ways to reseal the bag of coffee once it has been opened: Close the original seal and twist the tie or clip; secure it with tape or fold over one inch of paper over the hole before twisting it shut.

How long fresh coffee stays good in a properly sealed bag depends a lot on how well it was packaged and stored in the first place.

Why Do Coffee Shops Like Starbucks And Lavazza Use Thicker Bags?

Branded coffee, such as Starbucks or Lavazza, now comes in more robust packaging. These bags have existed for a while, and some are so strong that they can defy being run over by a car! But why are their coffee bags so thick?

Stronger coffee bags are now being produced by well-known coffee brands so that oxygen cannot readily enter the bag, and their quality coffee beans will stay fresh for a longer time. 

The thickness of the bag makes it easier to reseal because it is less likely to tear or be opened during transit. Plus, with a thicker bag, there’s room for more beans and grounds to be used in your brew, which means you’re getting better value out of your purchase. 


Learning how to open and reseal coffee bags is crucial. If you know how to store coffee properly, it can last up to a month or more! 

Whether you keep a fresh roast coffee in a paper bag or transfer it into airtight glass jars is up to you. 

Remember to fold the top of the bag and seal it with tape if you intend to roast fresh coffee and keep it in a bag. 

Hopefully, this article has taught you the coffee bag’s real purpose and how to properly open and reseal a coffee bag.
