If you are anything like me, you love a good cup of coffee. I don't like to drop all my money at coffee shops, but I will spend a little extra to make good coffee at home. After spending a little extra money on the "good stuff" the last thing I want is for it to go bad; after all what is the point of "good" coffee if you're just going to let it go bad. My coffee counter is one place in my home where my VacMaster® gets almost daily use.
It is important to know that your roasted coffee's biggest enemies are:
Air and Moisture
There are many methods I have seen people try to keep their coffee fresh, and while I can't say that those don't work, I can say that my VacMaster® keeps my coffee fresh and delicious. I use the VacMaster® Full Mesh Zipper bags when I know I will use the coffee fairly quick after I open it, and I know I will not be re-vacuuming. I use Full Mesh Vacuum Sealing Bags when I know I will want to re-vacuum after each open to keep my beans as fresh as ever. The vacuum works to keep the air and moisture out of the bag. It is important to know that right after roasting coffee beans will emit CO² gas for a couple days, and if vacuum sealed at time, may burst the bag as the gas is emitted. So if you roast yours, for the first couple days I would put a few very small holes in the bag to allow the gas to escape, then transfer beans to a new bag for storage.
This is probably the easiest coffee bean enemy to control; a kitchen cabinet is a great place to keep the vacuum sealed coffee beans to keep them out of the light.
Most of the time, heat is also easy to control. This could be tougher if you live in an extremely hot climate, and it is hot inside the house. Most of the time as with light, heat can be avoided in a dark cabinet.
Green Coffee Beans
If you do happen to be a home roaster it is great to store your green coffee beans in a vacuum sealed bag from the get-go, especially if you buy in bulk. There is no need to worry about CO² in this situation, because the gas is a bi-product of roasting. At this point the same rules apply; protect these beans from the coffee enemy's and store in a cool (not cold) dark place.
