So can cold brew coffee be heated up? Cold brew coffee can easily be warmed up without losing much taste by using diluted cold brew and heating it with boiling water with a 50/50 ratio. You can also heat up the cold brew in a microwave and dilute with cold water, but it won’t taste nearly as good.

How to warm up cold brew coffee

So which is the best way to warm up your cold brew coffee? Now that you are aware that you can heat your cold brew coffee, it’s better to learn how to have it done.

There are a couple different things you will need to do this correctly! Whether that be making the cold brew, the coffee itself, or the kettle to boil the water. Here are my recommendations for yah.

Dilute the cold brew with cold water

Alternatively, you can start by heating your concentrate and then diluting it with cold water. The only concern is that this method can affect the taste of your coffee.

In your pot, heat enough water and once the water starts boiling, turn off the heat source. Preheat your cup by adding hot water into it before discharging it.

Transfer your cold brew concentrate into the cup. Dilute the concentrate using hot water.

Your cold brew is now hot and ready for consumption. To enhance your coffee’s taste, you can dilute your concentrate with milk. All you need is to add hot water into your cold brew to warm it before adding milk into it.

Note that issues can arise in the second method, especially if you leave your cold blew coffee heating up for too long since this can result in chemical reactions, leading to the formation of unpleasant coffee taste. Once you follow the above steps, you will notice the beauty of heating your cold brew coffee.

What is cold brewing?

Cold brew is a brewing coffee method that comprises soaking grounded coffee beans in water at room temperature or even cold water rather than hot water. Like you can serve your hot-brewed coffee iced, you can still warm up your cold-brew coffee and serve it hot.

However, the process may be lengthy but be assured of a smooth and a flavoursome coffee during the cold season. It is easier to prepare a batch of your cold brew coffee if you have well-stored concentrate, especially in an air-free container.

It is valuable to note that since various coffee soluble dissolve at multiple rates, most of those that result in unpleasant bitter taste does not dissolve when using the cold brewing technique.

It is one reason why most vivid coffee drinkers prefer the cold brewing method when preparing black coffee as it is more pleasant and sweeter than the hot-brewed coffee.

Another advantage of cold brewing is that it isn’t a must to have expensive coffee gears to prepare your coffee using this method.

Why would you want to heat up cold brew?

Of course, the burning question you probably have is why in the world would you want to heat up cold brew anyways? Wouldn’t it be better to just make your normal cup of coffee?

Well, as we discussed a bit above, cold brew is not nearly as acidic as regularly brewed coffee, and is desired by people for taste and for just the fact of not having the acidity.

In the end though, cold brew drinkers generally like a hot cup of coffee in the morning just like the rest of us, and these are some great ways of doing this.


Regardless of who you are, cold brew is a great tasting cup of coffee, and it is awesome that you have the flexibility to be able to easily heat up a cup and have it for your morning cup of coffee.

In the end, if you already have a pre-diluted batch of cold brew, it will even be easier to heat back up than to create a whole new batch of hot coffee.
