Varieties of Coffee Beans and their Shelf Life
Different types of coffee beans have varying shelf life. Arabica coffee beans are known to stay fresh for longer periods than robusta beans owing to its lower oil content. Increasing the roast intensity can also reduce the coffee’s shelf life due to the loss of natural oils during the roasting process.
Below is a table containing examples of common varieties of coffee and their shelf life:
|Coffee Type||Shelf Life (Days)|
|Arabica||180 – 365|
|Robusta||60 – 120|
|Espresso Blend||30 – 90|
It is essential to remember that environmental factors such as temperature, humidity, exposure to light and air can cause coffee to age faster. Also, freshly roasted beans produce carbon dioxide that needs to release for up to five days before packaging; otherwise, it can cause negative impact on the beans’ taste and aroma.
One interesting fact about coffee is that it can be aged intentionally like wine or cheese. A few years ago, a Yemeni man found a stash of old coffee in his dead father’s basement. The man recognized its value and sold it for around $400 per pound – double its weight in gold! This type of coffee undergoes ageing through controlled storage conditions, giving it an entirely new flavor profile resembling tobacco or cedarwood aroma with zero acidic taste.
Roasting level is to coffee what a tan is to a beachgoer – too much and you’re burnt out, too little and you’re just plain boring.
Achieving the perfect roasting level can greatly affect the shelf life of coffee. The right level of roasting depends on various factors, including the type of coffee, its origin, and the desired flavor profile.
|Roasting Level||Description||Shelf Life|
|Light Roast||Coffee is roasted until it reaches a pale brown color with no oil on the surface.||Shorter shelf life due to higher acidity levels and retention of moisture from insufficient roasting.|
|Medium Roast||Coffee is roasted until it reaches a medium-brown color with some oil on the surface.||Moderate shelf life due to balanced acidity levels and well-developed flavors.|
|Medium-Dark Roast||Richer, darker color than medium roast with slightly oilier surface.||Longer shelf life than light roast due to less acidity and better developed flavors.|
|Dark Roast||Coffee is roasted until it reaches a dark brown color with visible oil on the surface.||Shorter shelf life due to more oil and less moisture. Pungent bitter taste. Over-roasted taste could overcome many desirable ones.|
The shelf life of coffee may be prolonged by buying whole beans and grinding them before brewing, as ground coffee has a shorter shelf life than whole beans.
“Even the best packaging won’t save your coffee from going stale quicker than a bad stand-up comic.”
Shielding the brew: the impact of wrapping on coffee bean lifespan can’t be overstated.
Get to know your packaging! Below we’ve detailed four commonly employed materials, how they influence the bean and their advantages/disadvantages.
|Paper||Permits air flow/Protects against moisture buildup, but is not airtight.||Economical/Less landfill waste.||Short shelf life/ Can only be used for certain roasts.|
|Tin Cans||Airtight protection/Blocks sunlight preservation; decreases flavor degradation.||Durable/Substantial resale value.||Cost.prohibitive/Large carbon footprint/Cannot see contents/Leached chemicals potential.|
The preceding table provided information about wrapping, however, below are some additional tips to extend your coffee’s freshness. Keep coffee in a dark and dry place with proper storage temperatures. Use beans within two weeks after roast date for optimal freshness. Grinding beans accelerates deterioration—grind only what you need before each brew.
Don’t let stale coffee cramp your style!
Invest in top-tier packaging and storage like a vacuum sealer or an airscape container to ensure that morning pick-me-up remains as smooth in week two as day one.
Let’s be real, the best way to store coffee properly is to never let it sit long enough to need storage in the first place.
