    If you are really talking about preserving your coffee for later use, then it is best to store the cold brew. The reason is concentrated cold brew is not ruined easily and you can enjoy a batch of refrigerated cold brew for 10 to 14 days. However, as an expert opinion, it is practically observed that after 7 days, the aroma and flavor of cold brew starts fading out. That is why you should consume stored cold brew within 7 days of storing inside the fridge.

    Moreover, if you have added more water to the cold brew concentrated, then the shelf life within the fridge is shortened to just 2 to 3 days. To check whether cold brew has gone bad, you should always check for less flavor and aroma as well as any development of acidic taste or mold.

    Similar to cold brew, iced coffee can also survive for up to 2 weeks. However, the conditions are similar as that of cold brew coffee. The concentrate should not be diluted with water, otherwise it will get ruined within 2 days even if it is inside a fridge. To avoid depletion of taste and aroma, it is recommended to freeze the iced coffee concentrate. Moreover, store the coffee inside a sealed food-grade container. In this way, you can not only increase the lasting of coffee inside fridge, but also protect against reduction of aroma and flavor.

    • How Long Does Ground Coffee Last in the Fridge

    Storing Coffee in the Fridge – Drawbacks

    3. Storing Coffee in the Fridge - Drawbacks

    Though storing coffee inside the fridge is really an amazing part, however, it also have certain downsides. If the coffee is not stored properly within the fridge, by not following the correct method, it can become really problematic. Some of the main drawbacks of storing coffee in fridge are:

    • Flavor Degradation

    As we know that each coffee has a certain expiration period, even if it is stored inside the fridge. For example, if a certain coffee can last for as long as 7 days within fridge, then you should not use it after the 4th or maximum 5th day. The reason is, though the coffee will be hygienic and safe, however, after half-life, the flavor as well as aroma starts degrading. Thus, the coffee doesn’t have its original and natural taste due to flavor/ aroma degradation.

    • Picking Aromas from Other Food Items

    Every refrigerator has certain food items that are well known for spreading their aromas to other food items. For example, if it is an old piece of cheese, or some mashed garlic or onions, then this aroma will spread to all your food products. In case of stored coffee, if the container is not properly sealed, then the pungent and stinky aromas inside the fridge will spoil the original natural aroma of your coffee. In the end, you will have a stored coffee with a ruined pungent aroma.

    As a quick tip, if your fridge has some stinky smell, then solution is placing a cup of ground coffee for some hours. It will extract all the stink and pungency and every bad odor inside the fridge will disappear.

    • Storing Coffee in Frozen Form

    First of all, if you are going towards storing your coffee inside fridge, then it is always advised to freeze it. Just tossing the coffee inside the fridge will do no good. Though it will serve the purpose, however, if freezing the coffee extends the shelf life even further. As an example, liquid coffee will last for 4 days, but a frozen batch will expire in no less than 7 days.

    • Using a Sealed Food-Grade Container

    Second approach must be using a food-grade contained which is completely sealable. A good option in this context is using a sealed glass air tight jar. Make sure the container is air tight as well as of food grade material. If the container is not air tight, then the coffee will react constantly with oxygen, which will result in ruining the whole aroma and flavor of refrigerated coffee.

    • Avoid Diluting with Water

    In preparation of a coffee batch for storing inside the fridge, the biggest mistake is using more amount of water.

Therefore, it is recommended to store coffee concentrate in a fully concentrated form without using too much water.

    Does Coffee Expire

    In this world, everything expires, including coffee. A question then arises; what is the coffee expiration date? If we talk about coffee grounds, that are manufactured and properly stored inside sealed packages, then you will have a long expiry date of one to two years. But you have to ensure that after usage you properly seal the bag and then keep it inside the fridge.

    If we look at freshly ground coffee, then it is best to consume it within first 20 to 30 minutes. Because after this time, the coffee grounds starts losing its flavor. On the other hand, if you want to store this fresh grind for later usage, you can store it in the refrigerator in an air-tight package. After this, you are good to consume this batch any day within a week.

    For refrigerated coffee drinks, we can see that for each coffee there is a different expiry time. For some coffees, it is 4 days, for others 7 days and a few 2 weeks.
