    1a. cold brew coffee vs iced coffee

    One of the main difference between the two is their method of preparation. Iced coffee is brewed using hot water (similar to conventional coffee making) initially and then poured over some ice cubes or chilled inside a refrigerator. As a result, you get an iced coffee where the poured over ice one has a sort of diluted flavor due to ice cubes.

    On contrary, cold brew coffee does not involve addition of hot water followed by cooling of coffee drink. Rather in cold brew coffee, the beans are soaked in cold water. Then either using a jar (such as Mason-Jar) you can prepare a cold brew concentrate or directly prepare cold brew coffee using a cold brew coffee maker. As compared to iced coffee, cold brew coffee has its original and optimal taste, without any bitterness or diluted flavor.

    Whether you want to heat some food or a beverage like coffee, a Microwave oven offers a quick as well optimum heating. For cold brew coffee, microwave oven based preparation is quite simple. However, there is a great confusion in this regard because oven based heating of cold brew coffee is only recommended for a certain types of ready to drink cold brew coffees.

    Most of the coffee drinkers make a mistake of putting their cold brew concentrate inside an oven. It will destroy its ingredients and believe me, you cannot take even a single sip of such a bitter and worsened heated cold brew. That is why if you have cold brew concentrate and not a ready cold brew, never go for microwaving it.

However, in regards to heating cold coffee, there are a number of reasons as why to do this. Below are some of the main motives behind heating a cold brew coffee:

    • Lower Acidity

    Lesser amount of acidity is one of the main reason behind heating a cold brew. However, as per research there is a great debate, research and contradictions on this topic. Some people think that due to dilution with water as well as quick reaction of oxygen while heating, the acidity is considerably reduced. That is why most of the people having an upset stomach doesn’t feel any issue while drinking a cold brew in its hot form.

    For others, there is no difference in acidity whether the cold brew is cold or hot. They think that it greatly depends on how concentrated a batch of cold brew is prepared and not on heating. But still, as compared to other coffees, cold brew coffee is already less acidic in nature.

    • Big Batch of Coffee

    Cold brew concentrate can be easily preserved inside a refrigerator for a number of days. Most of the methods to prepare a heated cold brew involves the usage of a cold brew concentrate. Similarly, each of these heating method of cold brew concentrate involves addition of water. That is why in a single go you can easily prepare from a single cup to as bigger batch of coffee as you want.

    Preparing a big batch of coffee is not only convenient but also saves time as well. Similarly, if you don’t want to go through the pain of making fresh coffee every day, you can prepare the cold brew in batches and then preserved inside a fridge for up to two weeks. It is highly recommended to always store your preserved coffees in an airtight container or jar to avoid any birth of microbes or germs, etc.

    • The Heart Wants what it Wants

    Finally, the most important reason behind heating a cold brew coffee is because your heart wants it hot. There is a chilled weather or your body is in need of a hot beverage but you have the cravings for cold coffee. So, in this case you cannot fight your heart, just pick up your cold brew and heat it up.

    Things to Avoid When Heating up Cold Brew

    Heating up a cold brew coffee is surely an amazing thing to enjoy. But at times, due to certain mistakes, we do not enjoy the real essence of preparing an amazing beverage. Therefore, you should avoid some of these things whenever you are in a mood to heat up cold brew coffee:

    • Cold brew concentrate should not be kept for more than 2 weeks inside a fridge.
    • Always go for a 1:3 to 1:5 proportion of coffee to water ratio when preparing a cold brew concentrate.
    • Avoid using an electric kettle if you have some other container to heat up the brew. Using electric kettle, the heating is quite easy, but later on to clear that mess is a real pain.
    • Never ever put your cold brew concentrate inside an oven to heat it up. The microwave method is only recommended for ready to drink cold brew and not cold brew concentrate.
    • The frothing method should only be used if there are no other heating alternatives available.

    As a simple and easy method you can use a microwave oven to heat up your iced coffee. Other methods include heating up iced coffee slowly over stove or by adding some warm water. But one must keep in mind that iced coffee is not so saturated like cold brew concentrate. Therefore, by adding water in any form will alter its taste and you are not going to really enjoy it.

    Does Warm Cold Brew or Iced Coffee Taste Good?

    First, let’s talk about the taste of a warmed up cold brew coffee. If done properly, by following the above mentioned methods, you will not face any alteration in the taste, texture or flavor. Believe me, taste wise, a warm cold brew offers an amazing taste as compared to other hot beverages. Therefore, you should not be afraid to heat up cold brew coffee.
