Does Boiling Water Ruin Instant Coffee?


Instant coffee is a great option for those without time to brew a fresh cup in the morning, but you should know how to prepare it properly. A frequent question is whether or not boiling water will ruin instant coffee as it does with ground coffee.

As a general rule, boiling water doesn’t ruin instant coffee because instant coffee is pre-roasted at a much higher temperature and then goes through a secondary process of preservation and additives. The temperature of the water used to prepare instant coffee is the brewer’s preference.

That’s a simple answer, but there’s a bit more to it. We’ll discuss in more detail below, as well as talk about how to properly prepare a cup of instant coffee, how to get more enjoyment out of it, and even go over a few top brands to stock your pantry with.

Why Doesn’t Boiling Water Ruin Instant Coffee?

Instant coffee is put through a “second process” during production, and that’s the main reason that some boiling water won’t hurt it. This process is meant to increase the shelf-life and make it much more practical for people on the move.

Here’s how they make instant coffee, and why that’s important:

  • Ground coffee goes through the same steps as instant coffee in the beginning. 
  • The beans are roasted at 370 to 540 degrees Fahrenheit, then ground into a fine powder.
  • Instant coffee then goes through a secondary process where the powder gets dehydrated. Then chemicals get added to prevent clumping and help preserve it. 
  • That secondary process means that adding additional boiling water isn’t going to affect the taste in the same way that it would in traditional ground coffee.

Ground coffee goes through no other process than cleaning it and roasting it, whereas instant coffee has additives and preservatives in the finished product. Without this second process, fresh ground coffee retains a rich aromatic flavor, but that flavor can also be altered by using boiling water to release bitter compounds in the coffee.

How to Make Your Instant Coffee More Enjoyable

While convenient, instant coffee isn’t always exciting. There are many ways to improve your cup of instant coffee. Let’s explore a few ways to punch up your morning joe!

Buy High-Quality Instant Coffee

The brand can play a role in how enjoyable the coffee can be. Instant coffee is just like anything else you get what you pay for. If you grab that dollar box, then expect a dollar cup of coffee.

While there are thousands of brands to choose from there are only a handful of brands worth consuming. It’s not always the best value to buy at the cheapest prices. In fact, with coffee, that can leave you with a cup full of mud.

Use Clean, Filtered Water

As water is the base of the beverage it can play a key role in the quality of the cup. You’ll never get a cup of good instant coffee when using bad or off-taste water. 

Filtered water is the best way to go here. That way you can ensure that you don’t get any mineral or chemical aftertaste in your cup. 

Experiment with the Ratio of Coffee to Water

The amount of coffee you use per cup is another way to ensure a more enjoyable cup of Joe. The general recommendation is to use around a teaspoon and a half per cup of water. 

Now, this, of course, depends on your taste, so experiment away!

Try Different Kinds of Instant Coffee

Also, try different kinds; there are thousands of different flavors from chocolate to gingerbread and everything in between. So, if one of the flavors doesn’t suit your taste, you got plenty of other options.

If you’re having a hard time figuring out which flavor to go with, get a variety pack. You can order a variety pack online with anywhere from 10 to 50 different flavors. It might take some time but once you’ve finished with that you should be an instant coffee connoisseur. 

Try Some New Flavorings

There are also a variety of flavorings and tastes you can use to bring a new kick to your instant coffee. Here are a few of our recommendations:

  • Flavored creamers can be a tasty and fun seasonal way to spice up your morning cup
  • Cinnamon is a classic standby to add a bit of warmth to your cup. Add a touch of ground clove too for a fall treat!
  • Honey is useful for more than just tea. A bit of honey in your cup of instant coffee can smooth it out and give it that little hint of sweetness you’re looking for.
  • Heavy cream or whipped cream is great for those mornings where you just need a little pick-me-up.
