What is Cold Brew Coffee?

What is Cold Brew Coffee?

Cold brew coffee is a form of java made with cool or ambient temperature water in lieu of hot. The distinctive taste of iced coffee and the ability to make it without a machine are making it increasingly sought-after. Cold brew coffee also contains less acidity than regular hot-brewed coffee, making it easier on sensitive stomachs.

Cold brew coffee is a brewing process in which coarsely ground beans are left to steep in cold or ambient temperature water for an extended duration, typically spanning from twelve to twenty-four hours. The result is a smooth, full-bodied cup with low acidity and sweet notes like caramel and chocolate.

Benefits of Cold Brew Coffee:


One major benefit to cold brewing your own cup at home is that you can customize the strength by adjusting the ratio of grounds to water used in the process. This means you can make stronger cups if desired, as well as weaker ones depending on your preference or caffeine needs for any given day.

No heat needed

Additionally, since there’s no heat involved in this process, you don’t have to worry about burnt flavors from over extraction like you do when making hot-brewed coffees – which often results in bitter tasting cups.

Prepare with simple effort

Finally, because cold coffee requires little effort (just mix grounds & water.), it’s much more convenient than having to wait for your traditional drip machine every morning before work/school starts.

Steps to make a cup of coffee

Making your own batch at home only takes three simple steps.

Step 1:

First off, grab some coarsely ground beans (the coarser they are the better) then combine them with filtered water inside a container, stirring gently until all particles have dissolved into solution completely (about 1 part grounds to 4 parts water).

Step 2:

After that, just let everything sit overnight so all those lovely aromas and flavors get extracted properly.

Step 3:

Finally, strain out any remaining solids using cheesecloth or paper filter before serving chilled over coffee ice cubes or warmed up slightly if preferred.

Cold brew is an ideal way to experience the taste of your go-to coffee beans without the astringency and sharpness.

Main Takeaway: Cold brew coffee is an increasingly popular method of brewing which requires no heat and produces a smoother, less acidic cup than hot-brewed coffee. It’s easy to make at home with only four steps; simply mix grounds & water, let sit overnight then strain out any solids before serving chilled or warmed up slightly.

Is it Safe to Put Hot Coffee in the Fridge?

Yes, it is safe to put hot coffee in the fridge. Nevertheless, you should take note of a few considerations before refrigerating hot coffee.

Hot coffee should not be stored at room temperature for more than two hours, or in the fridge for longer than four days as bacteria can grow quickly and make you sick if consumed.

This is because bacteria can grow quickly when food or beverages are left out too long and can make you sick if consumed. Furthermore, if you place hot coffee in a cold receptacle, it may result in moisture accumulating inside your fridge that could potentially lead to mold growth.

Pros and Cons of Putting Hot Coffee in the Fridge


  • Storing hot coffee in the fridge can hasten its cooling, allowing you to enjoy your drink sooner than if left out. This means that you won’t have to wait as long for your cup of joe.
  • Another benefit is that refrigerating leftover coffee helps preserve its flavor and aroma since air exposure causes both to diminish over time.


  • On the other hand, one disadvantage of putting hot coffee in the fridge is that some people find cold drinks unappealing compared to warm ones; therefore, they may not enjoy their morning brew as much after taking it out from being chilled overnight.
  • Iced coffee is generally prepared by brewing coffee at a low temperature to restrain the coffee from becoming bitter. If you prepare iced coffee by refrigerating hot coffee, certainly the coffee will become bitter and it won’t taste as good as hot coffee.

Steps for Storing Hot Coffee in the Fridge

If you decide to store your freshly brewed cup o’ Joe in the refrigerator, there are a few steps you should take beforehand.

First off, let your drink cool down slightly before placing it into an airtight container; this will help prevent condensation from forming inside your appliance while also ensuring maximum freshness once ready-to-drink again later on.

Secondly, make sure there is enough space between containers when stacking them together; this allows proper airflow throughout all items stored within so none get spoiled due to overcrowding issues either.

Finally (and most importantly), always label each item with its date and time placed inside; this way nothing goes bad due to unnecessary prolonged exposure during storage periods.

Tips for Storing Hot Coffee in the Fridge

Before storing your hot cup of joe, consider how long it will be in the refrigerator and what kind of container is best for storage.

  • It is best practice to transfer your leftovers into an airtight container before putting them into the fridge since this will help prevent further oxidation from occurring while also keeping out unwanted odors from other foods within your refrigerator space.
  • Furthermore, try not store your leftovers longer than two days since beyond this point their quality may begin deteriorating rapidly leading to unpleasant tasting results when reheated later on down the line.
Main Takeaway: Storing hot coffee in the fridge can be done safely, provided certain measures are taken and it isn’t left for too long. With proper cooling, airtight containers, and labels with date & time information on them – your morning brew will stay fresher for longer.

What Happens When You Put Hot Coffee in the Fridge?

What Happens When You Put Hot Coffee in the Fridge?

Can alter its taste and quality

Placing hot coffee in the fridge can alter its taste and quality. When cold-brewed coffee is chilled, it produces a smoother flavor that many people enjoy. However, when hot coffee is refrigerated, it can become bitter and acidic due to the acids released during cooling.

Moreover, when hot coffee is put in the fridge, some of its unique flavors can be diminished. As such, refrigerating hot coffee isn’t recommended if you want to retain its full flavor profile.

Potential health risks

There are potential health risks associated with refrigerating hot coffee as well. If not stored properly or for too long, bacteria growth could occur which could lead to food poisoning or other illnesses if consumed.

Therefore, it’s important to ensure that any leftover hot coffee is cooled down quickly before being placed in the fridge so that bacteria won’t have time to form and multiply.

Main Takeaway: Refrigerating hot coffee is not recommended as it can have an adverse effect on the taste and quality, while also posing potential health risks. For optimal flavor and safety, it’s best to refrigerate coffee quickly after it has cooled, but discard any leftovers after two days.

Alternatives to Refrigerating Hot Coffee

Alternatives to Refrigerating Hot Coffee

Many folks rely on hot coffee to start their day, yet preserving it can be challenging. Refrigerating hot coffee is not recommended due to the effects on taste and quality of the beverage, as well as potential health risks associated with consuming cold-brewed coffee that has been stored in the refrigerator.

Fortunately, there are other ways to store hot coffee which will enable you to relish your beloved cup of java in its finest form.

Short Term Storage Solutions for Hot Coffee:

If you need to store hot coffee for a short period of time (up to one day), consider using an insulated thermos or mug that seals tightly. This will keep your drink warm while preventing any odors from entering the container and affecting the flavor of your brew.

Use airtight container

You can also transfer freshly brewed coffee into airtight containers such as mason jars or vacuum sealed bags before placing them in a cool, dark place away from direct sunlight or heat sources like stoves and ovens.

Doing this will ensure that your drink remains fresh until ready to consume again within 24 hours.

Use Freeze-dried instant coffees

For extended storage, freeze-dried instant coffees are an ideal option since they have already been roasted and ground. Once the freeze-drying process is complete, all that’s left to do is add water and enjoy.

The process of freeze-drying preserves the majority of flavor compounds found in regular brewed coffee without affecting its aroma or color; making it a great choice for daily consumption over prolonged periods.

Furthermore, storing beans whole instead of grinding them will also help keep their freshness better than preground varieties as oxidation begins right away once exposed to air after being broken down into smaller pieces – thus hastening staleness if not consumed soon after purchase/grinding.

Cooling down coffee with an ice bath 

You can cool your hot coffee down with an ice bath which will take around 8 to 10 minutes. To do this, take a non-insulated cup, and pour the freshly brewed coffee there. Then take a bowl of water and ice and put the coffee cup into the ice water. Wait for 8 to 10 minutes, your coffee will be cooled down.

Main Takeaway: Keeping coffee hot for an extended period is not ideal; however, using insulated containers and freeze-dried instant coffees can help preserve its taste and aroma. For the best results, store beans whole as opposed to grinding them when they’re needed again in order to avoid oxidation that causes staleness.

FAQs in Relation to Can You Put Hot Coffee in the Fridge

Is it safe to put hot coffee in the fridge?

No, it is not safe to put hot coffee in the fridge. This can cause bacteria growth and could potentially make you sick. The optimal way to keep your freshly made coffee is at a tepid temperature or somewhat warmer for a maximum of two hours before transferring it into an airtight vessel and storing in the fridge for not more than seven days. If you plan to store it longer than that, freezing is the best option.

How long can you store hot coffee in the fridge?

It is advised to avoid placing hot coffee in the refrigerator as it can cause condensation and lead to changes in flavor. A sudden shift in temperature can cause moisture to form on the liquid’s exterior, resulting in an unpleasant and stale flavor.

Additionally, storing coffee for too long may also lead to flavor changes due to oxidation or other chemical reactions. For optimal flavor, let your brewed coffee cool off before transferring it to a sealed container and keeping it in a chill spot where the sun’s rays can’t reach. This will help maintain its original flavor profile for up to one week.

What are the benefits of putting hot coffee in the fridge?

Putting hot java in the refrigerator can hasten its cooling process, resulting in a chill and tasty drink sooner. The cold temperature also helps preserve flavor and aroma compounds that may be lost when cooling at room temperature.

Putting your coffee in the fridge can give you more command over its consistency, texture and potency. Storing coffee in the fridge helps inhibit bacterial growth, thus preventing spoilage or off-flavors if left out too long.

Does putting hot coffee in the fridge affect its flavor or quality?

Storing hot coffee in the fridge can adversely impact its taste and quality. The cold temperature of the refrigerator causes compounds that contribute to taste, aroma, and body to break down quickly.

This results in an overall decrease in flavor intensity as well as a flat or sour aftertaste. Condensation on the cup’s exterior may also form when you remove it from the refrigerator, potentially further weakening its taste.

To preserve optimal coffee quality, store it at room temperature instead of refrigerating it.

Are there any potential risks associated with putting hot coffee in the fridge?

Yes, there is a potential risk associated with putting hot coffee in the fridge. Condensation in the refrigerator can provide a moist habitat for bacterial and fungal proliferation when warm liquids are placed inside.

Additionally, when warm liquid is placed in a cold environment it will cool down quickly and may not be as flavorful or enjoyable to drink. It’s best to allow coffee to cool naturally before placing it in the refrigerator.


In summary, the response to the inquiry of whether you can store hot coffee in a refrigerator is an emphatic no. Refrigerating hot coffee causes changes in flavor and texture that make it unpalatable for most people. Instead, cold brew or ice coffee are great alternatives if you want something cool and refreshing without sacrificing taste. For a consistently delicious coffee experience, investing in a quality coffee maker is recommended.
