Can You Use Cold Brew Coffee Grounds to Make Hot Coffee? Methods & Tips

Table of Contents

Yes, you can use cold brew coffee grounds to make hot coffee; however, you should expect a significant difference in the flavor of your coffee. The temperature of the water used in the cold brewing process brings about the difference in taste between cold and hot brewed coffee.

When using hot water to make coffee, the soluble elements in the coffee dissolve quickly, producing a beverage with a rounded flavor and a sweet-smelling aroma. The hot water also causes the chemical elements in coffee beans to oxidize, giving the hot beverage notes of acidity and bitterness.

Oxidation occurs with cold water too, but at a slower pace, which is why cold brew coffee has a smoother sweet flavor with slight acidity and no bitterness.

If you don’t mind the robust flavor of hot brewed coffee, just pop some coffee grounds into your coffee maker and brew a steaming cup of Joe.

However, if you want hot coffee but prefer the flavor of a cold-brewed beverage, there is a simple solution. Cold-brew your coffee the usual way, then warm it up and enjoy it as hot coffee

What Will Happen After Heating Cold Brew Coffee?

You might be worried that heating your cold brew coffee will ruin its unique flavor, but I assure you that it won’t.

At the end of the cold brewing process, you’ll remove the used coffee grounds. The resulting beverage will still have all the essence of cold brew coffee locked in, which can only be changed by altering the water ratio. This means that the only way to change the flavor composition of your cold-brewed cup of Joe is by adding water to it.

In light of this, you can heat your cold brew with no adverse effects except the evident change in temperature. The taste and caffeine composition will stay the same; hence you can enjoy your favorite brew of coffee even during the cold season.

Does Heating Cold Brew Coffee Make It Acidic?

Cold-brew lovers appreciate the beverage because it is naturally low in acidity, thanks to its brewing method. So, if you’re contemplating warming up your drink, you may wonder if the heat will make it more acidic.

Heating your cold brew will not raise its acidity because you will do so without adding coffee grounds to the liquid when you warm it. Since heating the coffee grounds is what brings out the acidity, their absence ensures that the tartness of your drink remains unchanged.

Can You Use Cold Brew Coffee in a Coffee Maker?

Yes, you can use cold brew coffee in a coffee maker. As the popularity of cold brew coffee increases, so does the number of cold brew devices on the market.

Even though you can make a cup of cold brew using a mason jar or a simple french-press coffee maker, you should invest in a proper cold brew gadget for a better experience.

There are several cold brew coffee makers on the market today; hence you might have difficulty picking one that best suits your needs. If you are in such a plight, consider the three factors below to help you choose a cold-brew maker that is just right for you.


Since cold brewing involves making large volumes of cold java, most brewers come in large sizes, making it difficult to store your beverage during the brewing process. Some have a large circumference that may take up a lot of your fridge space, while others may be too tall to fit into shelf spaces. Make sure you consider the overall size of the device So that it fits correctly in your space.


Cold brew coffee makers come with two types of filters – paper and stainless steel filters. Paper filters are best if you want a drink without ground residues at the bottom of your cup. However, cleaning paper filters can be a bit messy, especially when the coffee spills.

On the other hand, stainless steel filters are easier to clean and minimize waste; however, your final cup of coffee will have a lot of sediment at the bottom.

Easy to clean

After making your cold brew, you’ll have to remove the coffee grounds and clean the carafe of your coffee maker. So, choose a gadget that is easy to take apart for cleaning.

What Is Cold Brew Coffee Concentrate?

The cold-brew coffee concentrate is a stronger and denser version of regular cold brew coffee. It is a lot stronger in taste and needs to be diluted before drinking.

The method used to brew cold brew concentrate is 100-percent similar to that of your normal cold brew coffee. However, the contrast between the two is in the ratio of coffee grounds to water used.

The coffee to water ratio is 1 cup of water – 1/3 cup of coarsely ground coffee to make a standard cold brew. With that ratio in mind, you can make your cold brew concentrate by simply increasing the amount of coffee used relative to the water.

Can You Drink Cold Brew Coffee Concentrate Without Diluting It?

If you prefer strong caffeine drinks such as espresso shots, you will love the taste of undiluted cold brew coffee concentrate. However, I recommend diluting your coffee concentrate with some cold water to enjoy the immense flavor of your cold brew.

Always dilute your coffee concentrate with 50/50 concentrate to cold water ratio, then serve over ice.

Other Ways to Use Cold Brew Coffee Concentrate.

Apart from iced coffee, there are several other ways to enjoy your cold brew coffee concentrate. You can use it to make:

Hot coffee

You can make hot coffee every morning using cold brew concentrate. Simply add boiling hot water to a few ounces of your concentrate to make a nice warm cup of coffee.

Heated cold brew coffee is very convenient, especially for those who do not have time to make a fresh hot cup of coffee every morning. Just brew a lot of coffee concentrate over the weekend, store it in your fridge, then every morning, you can mix your brew with warm water to make a delicious cup of Joe.

Cold-brew soda

Cold-brew soda is a bubbly and more refreshing alternative to iced coffee. All you need is:

  • 2 oz. cold brew coffee concentrate

  • 8 oz. of soda water

  • 1 oz. of simple syrup and some ice.

Mix them all up and enjoy your bubbly drink whenever it’s warm outside.

Note: You are not restricted to the ingredients above. Feel free to customize your cold brew soda with other flavors of your choice for more enjoyment.

Alternative for Espresso

As you can see above, cold brew coffee is very versatile. You can enjoy it either hot, cold, or as an alternative for espresso. All you have to do is brew a lot of coffee concentrate, then use it to make any caffeine drink you desire.
