How Long Can You Keep Iced Coffee in the Fridge?

Have you ever wondered how long can you keep iced coffee in the fridge? We often get asked this question by our readers a lot! And the answer is, like most things in life…it depends. In this blog post, we’re going to dive into all things iced coffee so that you can make a delicious cup at home that will last as long as you need it to.

Though Iced Coffee brews as regular coffee, it is more concentrated than usual. All you need is to put ice into the mugs. So, it is easy to make iced coffee if you have concentrated brewed coffee.

The concentrated brew can last longer than the served iced coffee in the fridge. You have to follow some directives to keep it fresh even in the fridge.

How Long Can You Keep Iced Coffee In The Fridge?

Iced coffee is thickened coffee than the regular coffee we drink every day. Usually, it brews with hot water while putting in the double amount of ground coffee. This concentrate is called base coffee and serves with ice cubes. Since Iced Coffee mixes with ice, it has to be a concentrated base.

It brews hot because sweeteners can readily melt at this temperature. Ice cubes or chilled water dilutes it as well as cools it down immediately. You can have a cup of iced coffee at any time if you have the brewed concentration. But the common question is, can you put iced coffee in the fridge overnight?

Well, yes. You can put Iced Coffee in the fridge to store for future use. However, there are 2 cases for the fridge life span of Iced Coffee.

  • Case-1: you can put already served iced coffee in the fridge. But, make sure that you will drink it within 8 hours. It is the best time to get the taste as served right now. This drink will last 2-3 days if kept in an airtight pot. In this way, the life of iced coffee extends. But, always check the smell and color before drinking for safety purposes
  • Case-2: If you brew the concentrate (the base coffee) or bring it from your favorite cafe, it will last longer. Close the lid of the coffee container so that it has no contact with air. Place it in the fridge as soon as possible. It will be in good condition for 1-2 weeks. Check the smell, taste, and color each time you use the concentration. Mold grows in the base coffee and makes you sick if you are incognizant. Remember to use an airtight container always to store your coffee

Expert Advice on Keeping Iced Coffee in the Fridge for Longer

Storing coffee is not like putting a glass of water into the fridge. The beans, grounds even the drinks of coffee absorb the smell of your fridge. So, it is not wise to leave it in an open container. Here are some simple tips for storing iced coffee in the fridge:

Use airtight containers: Transfer the freshly brewed or prepared iced coffee into a clean and airtight container before storing it in the refrigerator. Airtight containers prevent the absorption of odors from other foods in the fridge and help retain the coffee’s flavor.

Let it cool before refrigerating: Allow the iced coffee to cool to room temperature before putting it in the fridge. Placing hot coffee directly in the refrigerator can raise the temperature inside the fridge and potentially affect other perishable items.

Note: Once your iced coffee is brewed and ready to drink, it’s important to store it properly so that it doesn’t go bad too quickly. First things first: never leave your iced coffee sitting out at room temperature for more than 2 hours. Room temperature is the perfect breeding ground for bacteria, so it’s important to keep your coffee cold if you want it to last.

Label and date the container: If you’re storing iced coffee for future consumption, label the container with the date when it was made. This will help you keep track of its freshness and avoid consuming it past its recommended storage duration.

Don’t store it for too long: While homemade iced coffee can typically last for 2 to 4 days in the refrigerator, it’s best to consume it within 2 days to ensure the best flavor and quality.

Avoid exposure to air: When storing iced coffee in the fridge, make sure the container is tightly sealed to minimize exposure to air. Oxygen can cause the coffee to oxidize, leading to a change in taste and aroma.

Limit additives and toppings: If you plan to store the iced coffee, it’s better to avoid adding whipped cream or other perishable toppings until just before serving. These additions can degrade quickly in the fridge and affect the overall quality of the coffee.

Store in the back of the fridge: Place the container of iced coffee towards the back of the refrigerator, as it tends to be colder and more consistent in temperature compared to the door or the front shelves.

Use clean utensils: When serving iced coffee from the container, use clean utensils to avoid cross-contamination or introducing any bacteria into the coffee.

Consider cold brew concentrate: If you enjoy a cold brew, you can make a concentrated batch and store it in the fridge for up to two weeks. This allows you to dilute it with water or milk when serving, providing a fresh cup each time.

By following these expert tips, you can enjoy delicious and refreshing iced coffee whenever you desire, while also ensuring its safety and quality during storage.

How To Make Iced Coffee

There is no distinct brewing process for Iced Coffee than regular coffee brewing. So, it’s simple as adding ice cubes to your brewed coffee.


  • Coffee grounds
  • A regular coffee brewer (French press, pour-over, or any other brewer)
  • Ice cubes or chilled water
  • Milk and Sweeteners (optional)
  • Serving cups


  • Take the double amount of coffee ground into a French press or any brewer for brewing
  • Pour the same amount of hot water into a French press as regular brewing. Follow the French press brewing method
  • After 15 minutes of brewing, collect the extraction. It makes a concentrated base for iced coffee
  • Add milk or sweeteners to the drinks if you prefer. It is optional
  • Now, you can pour the drink into a serving glass with ice cubes
  • Or, let it cool down entirely before storing it in the fridge

The Role Of Additives…

Yes, additives for iced coffee can play a role in how long it lasts. The shelf life of iced coffee can be influenced by the types of additives and toppings used. Consider the following crucial points:

1. Dairy or Alternative Milk: If you add dairy milk or alternative milk (like almond milk, soy milk, etc.) to your iced coffee, it can shorten its shelf life. Dairy products, especially fresh milk, have a limited lifespan and can spoil relatively quickly. It’s essential to pay attention to the expiration date of the milk used in the iced coffee and consider that date as the maximum storage time for your iced coffee with dairy.

2. Sweeteners: Adding sugar, syrups, honey, or other sweeteners to iced coffee does not significantly impact its shelf life. However, it’s essential to ensure that the sweeteners are dissolved properly in the coffee before refrigerating. Undissolved sugar, for example, could provide a medium for bacteria growth.

3. Whipped Cream: If you add whipped cream to your iced coffee, it is best to do so just before serving. Whipped cream is a perishable topping that will not hold up well in the refrigerator for an extended period. Adding whipped cream directly to stored iced coffee can result in the cream breaking down and affecting the overall quality of the drink.

4. Flavored Syrups: Flavored syrups, such as vanilla, caramel, or hazelnut, do not significantly impact the shelf life of iced coffee. These syrups are typically made with preservatives and have a long shelf life of their own. However, if the flavored syrup contains dairy or any other perishable ingredient, it’s essential to consider its expiration date as a factor.

In general, the primary factors affecting the shelf life of iced coffee are the freshness of the coffee itself, the milk or alternative milk used (if any), and the overall hygiene and storage practices. Properly brewed and stored black coffee without any perishable additives can last longer than coffee with dairy or other perishable ingredients.

Remember to use clean utensils, airtight containers, and maintain proper refrigeration to ensure the best possible shelf life for your iced coffee. Always use your senses (sight, smell, and taste) to check for any signs of spoilage before consuming stored iced coffee. If you have any doubts about its freshness, it’s better to discard it to avoid any potential health risks.

Iced Coffee And Cold Brew Are Not The Same

Both iced coffee and cold brew are popular cold coffee beverages, but they are produced differently and have distinct flavor characteristics. The following are the fundamental distinctions between iced coffee and cold brew:

Brewing Method

Iced Coffee: Iced coffee is made by brewing regular hot coffee using various methods such as drip brewing, French press, pour-over, or espresso machines. Once brewed, the coffee is allowed to cool and then served over ice. The cooling process can be accelerated by using ice cubes or refrigerating the brewed coffee.

Cold Brew: Cold brew is made by steeping coarsely ground coffee beans in cold water for an extended period, usually 12 to 24 hours. The coffee grounds are not exposed to hot water, which results in a much slower extraction process compared to traditional hot brewing methods.

Flavor Profile

Iced Coffee: Iced coffee tends to retain some of the characteristics of hot coffee, such as its acidity and brightness. It can be slightly diluted by the melting ice, and the taste is generally familiar to regular hot coffee, albeit cooler.

Cold Brew: Cold brew coffee is known for having a smoother, less acidic taste compared to iced coffee. The long steeping time in cold water extracts different compounds from the coffee, resulting in a milder and more concentrated coffee concentrate. Cold brew is often described as having a naturally sweeter and more chocolatey flavor.

Strength and Concentration

Iced Coffee: Iced coffee is typically brewed at regular strength and then poured over ice, which can dilute the coffee somewhat.

Cold Brew: Cold brew is made by steeping a higher coffee-to-water ratio, resulting in a concentrated coffee concentrate. It is often served diluted with water, milk, or alternative milk, depending on personal taste preferences.

Serving and Customization

Iced Coffee: Iced coffee is generally served with ice cubes in a glass, and it can be customized with milk, cream, sweeteners, and various flavored syrups.

Cold Brew: Cold brew is usually served over ice as well but is commonly diluted with water or milk to achieve the desired strength. It can also be sweetened or flavored as per individual preferences.

Both iced coffee and cold brew have their unique appeal, and the choice between them depends on personal taste preferences. Iced coffee provides a more familiar coffee taste, while cold brew offers a smoother and less acidic alternative for those who prefer a milder coffee experience.


When does iced coffee go bad?

You should drink iced coffee within 8-12 hours after the serving. It degrades quickly after adding water and additives to the base coffee.

Why Cold Brew Coffee is superior to Iced Coffee?

Cold-brew does not use hot water for brewing as Iced Coffee. Hot water brings out the acidity of bean oils. But, the Cold brew is less acidic and bitter comparing Iced Coffee. Cold brew is a sweeter and more pleasant drink.

Can you put a French press in the fridge?

Yes, of course. You can put the French press in the fridge while brewing Cold brew. It takes 18-24 hours for the making process. Remember to clean after every use of your French press. Otherwise, molds can grow in it, and it is unhealthy.

Can you refrigerate coffee beans?

It is better to store unsealed coffee beans in an airtight container. And always put the container in dry and moisture-free places. You can keep it in the fridge if it is a sealed bean pack. But it will not last for longer.

What happens when you put hot coffee in the fridge?

Putting hot coffee in the fridge will not speed up the cooling-down time. It takes the same time to cool down as a countertop. If you put hot coffee in the fridge regularly, it will be responsible for compressor failure.

Will cold brews go bad if they are not refrigerated?

Cold brew may go bad quickly if you keep it out of the refrigerator for lengthier periods. It will stay good for 16-18 hours at room temperature. If you intend to use cold brew longer or for a few days, you must put it in the refrigerator.


Though Iced coffee is not Cold Brew, it can serve you chilling satisfaction on summer days. Iced coffee’ lifespan is not also great as a cold brew. But you can save it in the fridge for a little longer. Iced coffee from cafés lasts for 12 hours even if in the fridge. And, the base of iced coffee will go longer than a week.

Now that you know all there is to know about iced coffee storage, go forth and enjoy a delicious cup at home! Just remember: the fresher your coffee is, the better it will taste. So if possible, try to consume your iced coffee within 24 hours of brewing for optimal flavor. But if not, don’t worry—a little extra time in the fridge won’t hurt!
