Coffee Storage Myths; Freeze Your Fresh Roasted Coffee and Other Popular Misconceptions
By: Vince Manzello
So you are finally fed up with that bland black liquid, you once called coffee, brewed from the finest can of generic supermarket grinds. You are finally outraged at the price of a single cup of designer coffee shop coffee. It’s now time to take matters into your own hands!
You invest in the latest technologically advanced coffee maker, including your very own coffee bean grinder. Even the engineers at NASA would envy the bells and whistles on this baby. You splurge on several pounds of the finest fresh roasted Arabica bean coffee the world has to offer.
You pop open the vacuum-sealed bag and release that incredible fresh roasted coffee aroma. Your eyes widen at the site of all those shiny brown beans as you begin to grind your first pound of gourmet coffee. You feel like a mad scientist as you adjust every bell and whistle on your space age coffee maker and you revel in this accomplishment as you finish your first cup of home brewed gourmet coffee. No more long lines and outrageous prices at the neighborhood café for you!
Now it’s time to store all those pounds of unopened packages of fresh roasted coffee beans and the unused portion of the black gold you have just ground. Then you remember what your mother told you; “Freeze the unopened beans & Refrigerate the freshly ground coffee”.
At this point, it would be best if you just returned to the supermarket and purchased a stock of those generic grinds you had grown to loathe. Having the best coffee beans available and using the most advanced coffee brewing equipment will do little to provide you with the best cup of coffee you desire if the beans are not treated correctly.
Looking at the facts, we learn that the natural enemies of fresh roasted coffee are light, heat and moisture. Storing your coffee away from them will keep it fresher longer. Therefore, an airtight container stored in a cool, dry, dark place is the best environment for your coffee.
But why not the freezer, It’s cool & dark?
This does make sense, but if it be the case, then why do we not find our supermarket coffee in the frozen food section?
Here’s why!
Coffee is Porous. It is exactly this feature that allows us to use oils and syrups to flavor coffee beans for those who enjoy gourmet flavored coffees. For this same reason, coffee can also absorb flavors and moisture from your freezer. The absorbed moisture will deteriorate the natural goodness of your coffee and your expensive gourmet coffee beans will taste like your freezer.
The coffee roasting process causes the beans to release their oils and essences in order to give the coffee its distinct flavor. This is the reason why your beans are shiny. These oils are more prominent on dark-roasted coffee and espresso beans and the reason why these coffees are so distinct in flavor. The process of freezing will break down these oils and destroy the natural coffee flavor.
So unless you don’t mind frozen fish flavored coffee, you should avoid using the freezer to store your gourmet coffee beans at all costs.
There are some exceptions to freezer storing your coffee, but you should proceed with caution! Fresh roasted coffee will remain fresh for approximately 2 weeks. If you have more than you can use in this 2 week period you can, & I shutter to say, freeze your coffee but you should follow these steps:
Apply the Freeze Once Rule. What this means is that once you take the beans out of the freezer, they should never go back in. The constant changes in temperature will wreak havoc on your coffee. The frozen moisture on your coffee will melt and be absorbed into the bean, destroying the coffee oils and allowing absorption of unwanted flavors. When you put it back into the freezer, you are repeating the process and destroying your expensive gourmet coffee.
Keep moisture out! Remember, moisture is coffee’s natural enemy. If you have a five-pound bag of coffee to store, divide it up into weekly portions. Wrap those portions up using sealable freezer bags and plastic wrap. If possible, suck out the excess air from the freezer bag using a straw or a vacuum sealer.
Remove the weekly portion when you need it, and store it in an air-tight container in a dry place like your pantry. And remember, Do not put it back into the freezer!
So when is it best Refrigerate Coffee?
Simply put, Never ever, unless you are conducting a science experiment on how long it takes to ruin perfectly good coffee. The fridge is one of the absolute worst places to put coffee. The reasons why not to freeze fresh roasted coffee also apply here.
Other Popular Coffee Myths Exposed.
Grind all beans before storing.
Absolutely not. Grinding the coffee breaks up the beans and their oils, exposes the beans to air, and makes the coffee go stale a lot faster, no matter how you store it. This especially holds true for flavored coffees! For the best tasting coffee, you should buy your beans whole and store them in a sealed container in a dark place . Grind right before serving!
Vacuum-sealed packaging equals fresh coffee.
Again, absolutely wrong. The coffee roasting process causes the coffee beans to release a gas by-product, specifically carbon dioxide. This gas release process continues for several days after roasting. In order to be vacuum sealed, the coffee has to first release all its CO² or it will burst the bag, which means that it must sit around for several days before it can be packaged and shipped. This sitting around begins to rob the coffee of its freshness. Vacuum sealing is best for pre-ground coffee, which we already know is not going to taste as good as fresh-ground coffee.
The best method for packaging and shipping is in valve-sealed bags. The valve allows the carbon dioxide gasses and moisture to escape but doesn’t allow oxygen or moisture in. Therefore, the fresh roasted coffee beans can be packaged and shipped immediately after roasting, ensuring the coffee’s freshness and taste.
A quick review for storing your gourmet coffee
Buy fresh roasted, whole bean coffee directly from a coffee roaster if possible.
Look for valve-sealed bags, not vacuum-sealed.
Store your coffee beans in a sealed container in a dark place.
Grind your beans just before brewing.
Enjoy!
