One of the most common misconceptions about coffee is how to store your coffee.
I love to buy and brew specialty coffee it is such a great joy. Many people have more coffee then you can drink in a month and wondering how to store your coffee. Allowing coffee to go stale and therefore allowing the taste to deteriorate? This doesn’t sound like the best idea. So I got to thinking its important to communicate the best way to store your coffee beans.
When talking about how to best store coffee it is important to know a few factors. Keeping happy and healthy can be a challenge. Coffee beans need to be away from moisture, air, light and heat, and temperature variations to reduce the chance of mold. Therefore, you want to store coffee in a dry, away from direct light, away from heat and airtight, at a fairly consistent temperature place.
Absolutely not. Storing coffee in the fridge isn’t a great idea, while it is cold and there is an increase change of moisture, and also because of the continual change in temperature which will occur every time you take the beans out of the fridge and then put them back in again.
This is the most popular I hear from people. For the same reason as above is a bad idea. If it is not for daily use then I feel it is ok, but should not be in your daily freezer or in the front of your freezer. I don’t like the idea of freezing coffee beans.
Vacuum sealed bag?
If you buy coffee in bulk like I do, you may see some bags of coffee which have long shelf lives. Vacuum sealed backs come in at over 12 months in some cases.
Unfortunately, there is no evidence vacuum sealing prevents coffee from going bad, so while a vacuum bag may keep a bag of coffee in a decent state for a month or so thanks to keeping it away from light, air and moisture after a month or so of the roast date it’s probably that the taste will begin deteriorating. I personally do not buy vacuum sealed from the store as most of the time they are well after the roast date and have lost those amazing flavors.
So Kris how should you store your coffee?
The best way is small batch from a coffee roasted. The best idea, in my opinion, to ensure your coffee is a fresh as the day it was roasted is to buy as local as you can that way the more likely to be safe from air, light, moisture and heat. Then move beans, bag and all, into an airtight container such as a Tupperware box, or any other airtight container, and to keep this in a fairly cool and dark place.
Coffee can’t go bad. Can it?
Yes but no. Not in the same sense as food, whereby if you were to consume it in a certain state it could cause illness. Coffee can develop mold and may not taste the same. Some compounds of the coffee (oils and such) can deteriorate over time, which will generally cause a flattening off of the aromas and flavours.
If you’re buying freshly roasted coffee beans, and storing your coffee properly, and if you’re storing whole coffee beans and grinding prior to use, which is the only way you should be getting your coffee, then you should be able to consume your coffee over a period of 4-6 weeks, and potentially up to a couple of months, if stored in a vacuumed container, without a deterioration in flavour.
Most important part to good tasting coffee is grind your own coffee.
There’s really no way around this, if you’re wanting to brew coffee at home and you want top quality, you really should be grinding your own coffee (The best grinders are handheld ceramic bur grinders. Followed my mechanical bur then far below are blade grinders). The reason for this is that much less surface area of the coffee bean and less that is exposed to the environment, when it’s in whole bean form, compared to once it is ground.
If you’re not grinding your own, you really should be aiming to store your coffee for no longer than a couple of weeks, even if very well stored.
