How do I keep coffee fresh? Let’s talk about roasted coffee, then about green coffee beans…
What are the options for storing your roasted coffee? And how should you be storing your Green coffee refers to the processed seed of the coffee tree fruit. Coffee is a flowering shrub that produces fruit. The seeds of the fruit are processed, roasted, ground and prepared as an infusion.: Coffee to maximize life span and quality?
After roasting your coffee, you have to put it somewhere! You can just use a ziploc bag or a mason jar…it’s up to you, but there are some nice containers available that are made specifically for coffee Green coffee can be stored much longer than roasted coffee: Roasted coffee starts to lose its aromatics in 10 days after roasting. Green coffee can be stored months without degrading quality. Very often the type and others that are great for helping you share your roasted creation.
Regardless, it’s best to keep roasted coffee away from sunlight, oxygen, extreme temperatures and humidity (elements that will make your coffee stale). If you are gifting coffee or storing it untouched for a few days, you will want to use a bag or container with a one-way valve. A valve allows for C02 to escape and keeps oxygen out.
If you are accessing your coffee often, a valve isn’t totally necessary since you will be exposing it to oxygen on a daily basis but it will help a bit if you are storing larger batches. Freshly roasted coffee should be treated like fresh produce since it’s flavor will start to degrade after a week or so. The Aroma refers to sensations perceived by the olfactory bulb and conveyed to the brain; whether through the nose or "retro-nasally": The aromatics of a coffee greatly influence its flavor profile and come from the perception will degrade first and the “cup quality” will follow.
These tins are very popular, affordable and work well. They store up to a pound of roasted coffee and there’s a one-way valve underneath. The sidewalls are a bit thin so it will dent easy if you are clumsy but will last for years if it just lives on your counter or in your cabinet.
If you are looking for a more robust coffee tin that also holds up to a pound, the Airscape is really impressive. One issue with large storage containers is the amount of oxygen that sits with your coffee once your stash starts to get low. The Airscape presses all that air out, leaving only coffee and the space between the beans.
These are the same bags we use to ship our roasted coffee in. They are extremely strong, with a thick foil barrier that keeps oxygen and light out. The one-way valve allows C02 a way out and you can use an iron to create a permanent seal above the zipper. Here’s a video showing how.
We say light is an enemy of freshness so why do we offer clear valve bags? A ¼ pound of coffee is only good for a few servings so we imagine a day or two of sunlight won’t have a chance to do noticible damage to your coffee’s flavor. We don’t recommend these for long term storage. They are mainly for sharing and gifting.
These are very handy if you like to weigh your coffee before brewing. You can pre-weigh your doses into a few of these put your scale away for a couple days. Aside from home use, they are great for travel or the office.
These are great for gifting as long as your coffee isn’t planning an extended stay in the bag. They are affordable and look great but don’t have much of a barrier to keep oxygen away from your coffee. Make sure whomever receives your gift of fresh roasted coffee, brews it before they attempt to Similar to aftertaste, but it refers to the impression as the coffee leaves the palate. Aftertaste is the sensations gathered after the coffee has left the mouth. We combine these to form the "final flavor off their oily tub of “Dark Roast Supreme Bold Holiday Breakfast Blend”. A lot roasteries sell their coffee in paper bags just like this so using these bags are your opportunity to live out your professional roaster fantasies (unless they are already a reality). They are compostable minus the tin tie and come in two sizes.
Green coffee is the dried seed from the fruit of a tree. In the past it was shipped in jute or sisal bags, which prevented coffee from becoming mouldy, but also exposed it to the
Green coffee is tough, dense, hard and resilient, but nothing lasts forever. You can expect green coffee to remain fresh for about 6 months (some say up to a year). We ship green coffee to you in clear zip bags. These are LDPE (recycling symbol “4” for plastics). The plastic provides a bit of a protective barrier and the holes us to get the air out. LDPE means Low-Density PolyEthelyene.
We recommend storing your coffee in these bags if you plan on roasting within a few weeks after receiving your coffee, or up to 2 months.
If you plan to store green coffee longer we recommend transferring the green coffee to glass, with as little headspace as possible, or using our Ecotact high barrier bags for green coffee storage.
We have the Ecotact bags in 1, 2 and 5 Kgs at Sweet Maria’s now, as an add-on item.
Learn more about our current understanding of green coffee storage and our Ecotact bags Here.
We don’t consider cloth or jute bags good for storing coffee long term any more. They look great but without a barrier liner, the coffee flavors might fade sooner than if stored with proper high barrier protection.
Consider that now we at Sweet Maria’s now import our coffee in typical jute or sisal woven bags but every single bag we bring in from all over the world has a high barrier inner liner. This is often referred to by the trade name of one brand, Grain Pro, because it was created to keep grain safe. But now it is a standard with high quality green coffee beans. We often use the brand Ecotact as well as A multi-layer plastic bag with a gas barrier. The bags have been shown to extend the flavor life of the coffee significantly over storage in jute or burlap bags.: A multi-layer plastic bag with a.
We still offer these in 1 pound, 2 pound, 5 pound and 20 pound sizes with our logo on them. They look nice but as you can see they are more for decoration now as we use a barrier liner inside all our green coffee.
These are the same bags we receive green coffee in from around the world. They are probably too big for you to store coffee in but our customers really like them for projects, decor, etc.

Glass! A mason jar or any resealable type used for food – provided you cleaned it really well and it has no smells!
How soon can I drink the coffee I just roasted?
Well, right away, but it will better if you can wait 12-24 hours. Even then you will see super fresh coffee emits so much natural carbon dioxide that water can’t fully saturate it. So use a “full immersion” brew method if that is the case: A simple coffee brewer also called a Press Pot: grounds and hot water are added to a carafe, allowed to sit for several minutes, and then a filter is pushed down to hold the grounds, Clever Dripper, perhaps an A portable coffee brewer that makes a unique dense brew, somewhat similar to an Americano.: The Aeropress looks like a giant syringe: coffee grounds are in the bottom, and when you depress the syringe it. For pourover drip of super fresh coffee, pre-soak the grinds for a long time.
In 2020 what is the best way to store green coffee?

What about freezing roasted coffee?
I think the net benefits outweigh the risks. For those who home roast their coffee it makes little sense. We don’t home roast a months+ worth of coffee … why? It’s fresh for 7-10 days, so long term storage of coffee doesn’t enter into it. Taking coffee in and out of a freezer damages it with each exposure to temperature and humidity change. Just store your home roasted coffee in a good barrier container with as little headspace as possible … glass, a valve bag, an Airscape, etc.
What about freezing green coffee?
There are some proponents of “cellaring” green coffee for long term use by storing it in high barrier vacuum packed bags in a commercial freezer. I tested this for a 1 year period and indeed, of all the combinations of material and storage I tried, the vacuum-packed (nitrogen gas flushed) bag that was frozen was best. By “best” I mean it had the least damage in the form or papery age taste when cupped beside the other methods I used in the 1 year trial. But when tasted next to the recent arrival of Refers to fresh shipments of green coffee within the first month or two of the earliest arrivals ... not quite the same as Current Crop, which means the most recent harvest. As a stable dried coffee from the same In coffee talk, it refers to a coffee-producing region or country; such as, "I was just at origin." Of course "Origin" for most product we use is not a beautiful farm in a temperate climate, (Kenya is the East African powerhouse of the coffee world. Both in the cup, and the way they run their trade, everything is topnotch.: Kenya is the East African powerhouse of the coffee world. Both), my frozen vac pack sample paled in comparison. I don’t see the reason to use the energy and storage space to keep coffee that ultimately ends up being an inferior cup, unless you have some special circumstance that makes that worth doing.
