It is also important for our discussion of heating up a cold brew. This is because most people assume that for some reason, the cold brewing process makes cold brew coffee impossible to heat up or that doing so will ruin what they love about their favorite type of coffee. Have no fear; the great thing about cold brew is that it is made from concentrate. This means that the brewing process takes place by steeping coarse coffee grounds in cold water for a number of hours to create a concentrate.

Most of the benefits people enjoy about cold brew, subtle flavors, less caffeine content, and lower acidity than your average cup of coffee, are derived from this brewing process, and they don’t go away just because you heat cold brew up. Because the grounds are removed at the end of the brewing process, the character of the concentrate is locked in and can only be altered by the ratio of water it is mixed with.

This means that heating up your cold brew will have no effect on it whatsoever besides the obvious change in temperature. Heating up cold brew also won’t change its caffeine composition, so doing so can be a great way to enjoy your favorite brewing method in the cold winter months. So Can I Heat up cold brew and can cold brewed coffee be served hot? Yes, they can. Can Cold brew coffee be heated, yes it can!

Does heating up cold brew coffee make it acidic?

Most people already know that cold brew coffee is naturally lower in acidity and appreciate it for this very reason. Few are aware, however, that this feature is due to the cold brewing process and unique for that reason from most hot coffees.

So, it stands to reason, if the cold brew is lower in acidity because of how it is brewed, does heating it up to undo all that good work? The short answer is no, heating up cold brew won’t raise its acidity.

This is for many reasons, chiefly that heating cold brew is normally done without the presence of additional coffee grounds; since it is the heating of the grounds that give coffee its acidity, their absence means that heating cold brew won’t increase its acidity.

What influences your cold brew’s acidity and caffeine levels more than heating it up is how strong you make your batch in terms of the ratio of added water. This is because all of the characteristics are in the concentrate, and adding more or less water can only lessen or heighten the effects of the concentrate.

So, while it may feel like you are cheating by heating up your cold brew to enjoy it warmly, don’t stress; you aren’t doing anything at that point to change the strength of your brew in any way other than by adding water.

What Not To Do When Heating Up Cold Brew

1. Never use an electric kettle to heat concentrate!

It isn’t that an electric kettle couldn’t heat up cold brew concentrate; it can. It is that doing so could potentially create a big gunky mess!

This is because the cold brew concentrate will stick to the coils that most electric kettles use during the heating process. Cleaning these coils can be a pain, and the residual concentrate can flavor the water you heat up afterwards. A good tip is to only ever heat up concentrate with water already mixed together and to never use an electric kettle to heat anything other than water.

2) Don’t put your cold brew in the microwave!

Never give in to the siren call of the microwave and stick your cold brew in one, thinking that in 30 seconds, you will have nuked yourself a cup of hot, cold brew; it isn’t that simple. The water and cold brew concentrate need to mix in a specific way that you can’t achieve if you just combine the ingredients and rely on a microwave to heat them Unless you are going to invest the time to properly heat the water, which will take at least a couple of minutes due to the un-even heating abilities of a typical microwave, don’t waste perfectly good cold brew on a flawed experience.
