It is always scary when your favorite whole coffee beans or ground coffee goes bad in the freezer. Especially if you have been keeping it in the freezer for a while and it suddenly shows up and starts to smell musty. So how do coffee beans go bad in the freezer? There are many reasons that coffee can go bad but there are also many ways to fix it. Here are some coffee tips for beginners that can help you fix common coffee problems.
First, try to avoid putting your coffee in the freezer if it is going to be used for brewing. This is especially true with whole coffee beans. For commercial grade coffee that has been sitting in the cupboard for quite a while, leave it in the freezer to help it maintain its freshness. If you store it tightly in the original container, the coffee will begin to break down because of lack of air circulation around it. Also, try to throw away coffee that has gone stale or has gone over a year without being brewed.
Second, when it comes to coffee that has gone stale, the sooner you stop brewing it, the better. As coffee ages, it begins to lose its flavor and aroma as well as its original flavor. Stale coffee has less aroma and less flavor than freshly roasted beans. It will taste like coffee that has just been sitting around in a cabinet or a cupboard.
Third, the best way to store whole beans for maximum freshness is in an airtight container. These containers should be made out of glass or plastic since glass doesn’t allow air to circulate properly and plastic doesn’t retain heat well. They can be stored either inside the freezer or in the refrigerator. Keep in mind that coffee beans lose their flavor as they age. So when brewing your next cup of coffee, choose a fresher batch and avoid using old coffee.
Fourth, keep the coffee beans in the original bag or canister in the freezer. The reason for this is because heat will cause oxygen to become present in the jar. The coffee will begin to break down because of this and the aroma will start to evaporate. You want to make sure the beans are kept in a dry area so that there is no moisture within them. The moisture will actually attract more oxygen molecules to the surface, and this will make the coffee stale faster.
Fifth, if you are grinding whole bean coffee then be sure not to reuse the coffee grinders. These coffee grinders are typically made from metal, which will quickly oxidize. The oxidation will cause your coffee to taste bitter. Also, the coffee grinders that are made of stainless steel will rust easily. To prevent oxidation from occurring, you should store your grinders in an area where it cannot come into contact with moisture.
Sixth, you should also not rinse out the coffee grinds after brewing. You want to ensure the oils remain on the grinds. Once the grinds have been rinsed out, you will notice the freshness of the coffee. By ensuring that the oils remain on the grinds you are ensuring that there will be no longer any danger of stale coffee.
Seventh, you should never rehydrate coffee that has been brewed. This is because coffee that has been rehydrated will lose its freshness and taste. Once the coffee has been rehydrated, you will notice that the coffee starts to acquire an oily taste. Once coffee begins to acquire an oily taste you should throw away that cup of coffee and brew another one. This is because coffee that has been rehydrated will quickly lose its flavor.
