Instant coffee vs ground coffee: Which should you pick?

Did you know that it’s the norm in Ireland to drink coffee daily? In fact, over three-quarters of Irish people can’t go about their day without a sip of this caffeinated drink, whether it is made of instant coffee vs ground coffee.

Some are not fussy regarding the type of coffee they consume, while others are more discerning. If you would like to cultivate your coffee knowledge and see which option is more to your taste, reading this guide is the perfect way to start your journey.

What is instant coffee?

Instant coffee refers to a water-soluble product made from coffee beans. One can make a drink from instant coffee by simply dissolving it in water. The history of instant coffee is said to date back to 18th-century Britain.

How is instant coffee manufactured? Producing it involves dehydrating a coffee bean concentrate and turning it into fine powder or granules.

What is ground coffee?

Ground coffee is a product made by washing, roasting, and pulverising coffee beans. At the end of the process, its granules can range from very fine to coarse.

Is ground coffee instant coffee? Making freshly brewed coffee grounds is more complicated, since it typically requires equipment. In several cases, one may also have to use a coffee filter, whose origin can be traced back to German housewife Melitta Bentz.

Ground coffee vs instant coffee: Which is better for your needs?

Explained in detail below are the major differences between instant and ground coffee:

In terms of cost

The types of coffee beans used to make instant and ground coffee point to one reason for the difference in their price ranges. The former usually comes from Arabica beans, while the latter is typically produced from the less pricey Robusta beans.

In Ireland, the price of instant and ground coffee starts at around €2 and €5, respectively, for a 200-gramme pack. Given the price difference, can you use ground coffee twice to save money? It is not ideal to do so, since the chemicals that give ground coffee its flavour would have already been extracted during its first brew.

In terms of preparation

Instant and ground coffee do not share the same brewing process. Making a drink from instant coffee is as easy as adding coffee crystals to hot water and stirring.

Meanwhile, brewing coffee using fresh ground coffee beans is an experience in itself. Whether you’re using a French press, a moka pot, a drip coffee maker, or another piece of equipment, the process will require water and, in some instances, a coffee filter.

In terms of flavour profile

When it comes to taste and aroma, instant coffee (vs coffee grounds) is less complex. Made using Robusta beans, instant coffee also tends to be much more bitter and somewhat tart. On the other hand, roasted Arabica coffee beans give ground coffee its smooth taste and aroma.

In terms of customisation

Another difference between ground and instant coffee is the degree of customisation that you can have with them. When brewing a drink with instant coffee, the main thing you can customise to your taste is the ratio of coffee extract to water.

Meanwhile, aside from the coffee-to-water ratio, you can choose a specific brewing technique and tools to create a ground coffee brew that suits your taste. Moreover, a wide variety of ground coffee roasts (light, medium, and dark) and granule sizes (from extra fine to coarse) means there are more ways to personalise a cup of coffee.

In terms of nutritional content

Is instant coffee good for health? Coffee, in general, has been proven to make one live longer, have a healthier liver, and enjoy better mental health. The amount of caffeine in instant coffee is slightly lower than that of ground coffee. This means it’s a better choice for those with caffeine sensitivities.

One study also showed that, compared to other types of brewed coffee, it has higher levels of phenols, which have antioxidant properties. However, it has more acrylamide, which is known to increase one’s cancer risk. But do know that the amount of acrylamide one could consume from instant coffee should not cause too much worry.

In terms of shelf life

Does instant coffee go bad? The short answer is yes, but it will take two to 20 years before properly stored instant coffee becomes unsuitable for consumption. 

Ground coffee, if left sealed in its original packaging, is safe to use until its best-before date. However, once opened, it will only remain fresh for up to two weeks.

In terms of eco-friendliness

There are opposing beliefs regarding which type of coffee has the most environmental impact. In a 2023 study, it was found that carbon dioxide emissions from instant coffee are five times higher than those from ground coffee. However, coffee filters—used mostly when brewing ground coffee—also generate a significant amount of greenhouse gases.
