Introduction
If you are a coffee lover and want to drink your favorite beverage daily but at the same time you are a busy person too, at that time you have only one option left, that is to make a large batch of coffee once and preserve it in the freezer for extended period usage. Suppose you make a large batch of coffee for your evening gathering but suddenly the plan is canceled, the only option left for you at that time is to preserve it in your refrigerator.
These are all the seniors that a coffee lover must suffer and at that time that person also thinks about one query, i.e. how long can brewed coffee stay in the fridge, what are possible ways to preserve coffee freshness and when will they find out that the preserved coffee is spoiled?
These all are the questions that bother a coffee lover. In this article, we will discuss how long can brewed coffee stay in the fridge and its necessary parameters in detail to solve all the curiosity of a coffee lover.
Factors that affect freshness
Before going towards how long can brewed coffee stay in the fridge, first we have to explore the factors that influence the freshness of brewed coffee. So, the main factors are as follows
Coffee to air ratio
Exposing coffee to air allows oxygen to react with coffee, causing oxidation, which results in aroma loss, bitterness and coffee spoilage. Hence, the overall coffee profile may be damaged if air exposure is increased. That is why the first factor that should necessarily be considered by a coffee lover before preserving is to seal their beloved coffee in an airtight container.
Temperature stability
Suppose you sealed your brewed coffee in an airtight container but still it spoiled. This may be because of the second factor that you should consider after putting that coffee container in the refrigerator and that factor is temperature stability. For perfect preservation, brewed coffee required almost 4°C to 4.4°C (40°F), which is ideally provided by a refrigerator. Reasons for weakened cooling, like frequently opening the door of the refrigerator, temperature fluctuation in the refrigerator and overloading the compartment, cause temperature instability, which increases the chances of oxidation and allows bacteria to grow, resulting in coffee spoilage.
Coffee with or without any additive
The third factor that can damage the preserved coffee profile is hidden inside the coffee and that is the additive ingredients. Normal black brewed coffee without any additional additive or dairy ingredient can last up to several days. But the coffee that contains additional ingredients like milk, cream, sugar or flavor syrups cannot last longer.
Because these additives contain additional nutrients like fat, protein and natural acids with low water activity, they can increase the pH level and promote bacterial growth and yeast production, resulting in coffee spoilage.
How long can brewed coffee stay in the fridge?
After understanding the factors, we conclude that the freshness and lasting ability of coffee depend on its ingredients and brew type. Some brew types have prolonged freshness, which still remains after freezing but some are found to be bad just after a short time period. In this section, we are going to find out the answer to our main query, i.e. how long can brewed coffee stay in the fridge according to their brewing type?
So, the lasting time of each brewed coffee is given as follows
| Brew type | Without additive | With additive | Reason | |
| With milk or cream | With flavored syrup | |||
| Drip Coffee | 2 to 4 days | 1 to 2 days | 2 to 3 days | Because of the hot brewing and then cooling down procedure, it may cause an oxidation process if it is not sealed well. |
| Cold brew | 8 to 10 days | 2 to 4 days | 2 to 4 days | Because of the low brew, which is less acidic in nature, the taste is maintained longer. |
| Espresso | 1 to 2 days | 1 to 2 days | 2 to 3 days | Similar to drip coffee, it spoiled immediately because being brewed hot and then cooled increases the chances of oxidation. |
| French press | 2 to 3 days | 1 to 2 days | 2 to 3 days | French press brew contains a steeping process, which extracts more oil and sediment, which will turn rancid over time, resulting in spoiled coffee. |
| Iced coffee | 1 to 2 days | 1 to 2 days | 2 to 3 days | The initial process of brewing hot and then cooling down emphasizes the importance of consuming it quickly. Otherwise, it will lose its freshness after the mentioned time span. |
| Nitrogen infused coffee | 2 to 4 days | 2 to 4 days | 2 to 4 days | It is a special type of brewing in which coffee is infused with nitrogen to make it creamier and smoother. But still it is not made for long periods like cold brew and can be spoiled in the mentioned duration. |
| Moka pot coffee | 2 to 3 days | 1 to 2 days | 2 to 3 days | Low temperature and high pressure brewing processes make it more robust but less intense in profile. This coffee type lies between drip and espresso. This profile may easily allow oxidation and condensation, which results in coffee spoilage. |
| Turkish coffee | 1 to 2 days | 1 to 2 days | 2 to 3 days | Because of making it strong, thick and unfiltered. It is highly concentrated in nature and contains dissolved solids, making it unsuitable for freezing and long lasting. |
The reason column in the above table well explained why coffee can be spoiled even without additives. But analyzing the graph of how long can brewed coffee stay in the fridge, you will find out that we mentioned two categories (three columns), without additive and with additive.
If you’re curious about why this time period is shorter if we go for the additive option. This is because of that factor, which was described in the above factor’s section.
How to store brewed coffee properly
After exploring the factors, table and necessary detail of how long can brewed coffee stay in the fridge, it is also necessary to acknowledge the procedure through which you can preserve your brewed coffee for a longer time period. And this knowledge will directly influence our main query, how long can brewed coffee stay in the fridge?
So, the steps to properly store brewed coffee are as follows
Steps to properly store brewed coffee
- First you have to take an airtight container, try to choose a glass bottle or stainless steel container that has a narrow opening neck.
- Second, you have to cool down your coffee if you have hot brewed coffee to freeze. It is better to preserve plain black coffee instead of coffee that contains additives, cool it down for a few minutes.
- After that, put your brewed coffee into that container and seal it properly.
- After brewing and pouring into the container, hold for almost 20 to 30 minutes. So, the temperature of the airtight container and the brewed coffee will be stable.
- Placed the container into the back of the refrigerator, so the temperature fluctuation due to frequent opening of the refrigerator door will not cause direct impact on that container.
- It is considered better if you label the container and mention the preservation date on it so you can track the storage period.
- Try not to open your refrigerator door again and again and let the container be cooled properly.
