<p>I would add to <strong>not</strong> store it in the refrigerator or freezer.  It would fare better at room temperature and dry than cold where it could be exposed to food smells and moisture.  You didn't ask, but also drink it as soon as possible if it's ground.  Whole beans will keep for awhile but ground coffee will start to go stale very quickly, even if stored properly.</p>
<p>The <a href="http://www.ncausa.org/About-Coffee/How-to-Store-Coffee" rel="noreferrer"><em>National Coffee Association</em> article on How to Store Coffee</a> advises this:</p>
<blockquote>
<p>It is important not to refrigerate or freeze your daily supply of coffee because contact with moisture will cause it to deteriorate.  Instead, store coffee in air-tight glass or ceramic containers and keep it in a convenient, but dark and cool, location. Remember that a cabinet near the oven is often too warm, as is a cabinet on an outside wall of your kitchen if it receives heat from a strong afternoon or summer sun.</p>
<p>The commercial coffee containers that you purchased your coffee in are generally not appropriate for long-term storage. Appropriate coffee storage canisters with an airtight seal are a worthwhile investment.</p>

I've been roasting coffee for five years, and have done lots of experimentation on coffee storage. Whole bean coffee improves for a few days after roasting, then goes downhill for about 7 days. To avoid this, you must freeze the whole bean coffee.

One of the first things I learned is - do NOT grind your coffee in advance. Everything I have read at various coffee forums states that ground coffee starts losing flavor and aroma within 15 minutes! This is very easy to test, and you can taste the difference easily. You should NEVER buy ground coffee - only buy whole bean coffee, preferably roasted within the last week.

<p>The oils in roasted coffee degrade as they are exposed to air (oxidization) as well as heat. As with just about any foodstuff moisture accelerates the spoiling process as well.

Even without vacuum storage you can preserve beans for a long time by placing them inside a ziplock bag or coffee bag with a 1-way air seal and pushing as much air out as possible and then following the above method of airtight, dark and cool storage. Following these guidelines should help to ensure the freshness and flavor of the beans for as long as possible. </p>

I find that coffee beans release gas stored within the beans. Storing them in a vacuum container is great advice, but the beans themselves may break the airtight seal. I'd certainly propose a vacuum bag that has a separate locking mechanism. Bags also allow you to tighten the space if / when you decide to use part of the beans, or if you simply do not have that many beans to begin with. The beans exhaling gas also shows that *any storage method* will only get you so far; a good excuse to drink the coffee sooner rather than later.

It's interesting how negative folks can get about freezing coffee.

There are a few places where freezing coffee has been tested to do really good things.

1) one good thing - is extending life (and flavour) of the roasted bean - when it's put down as soon after roasting as possible, and is only frozen/unfrozen once.

here's a ref that goes into detail of [a taste comparison between the frozen and fresh versions.](https://www.home-barista.com/store-coffee-in-freezer.html)

I saw no paper bags or canvases, as those are easily affected by the elements and even by the coffee itself, and often what you are given coffee in. I have found that if you keep the coffee in that, the coffee oils can come off in the bag possibly affecting the next batch of coffee in that. Though this is true for anything, even with the Coffee Vaults or plastic storage, if not cleaned properly between uses you will get a different tasting coffee. The paper and canvas I have also had experiences where the flavor of the canvas or paper starts coming through in the coffee, and I am sure this is also true for some other organic materials.
