Do Coffee Makers Distill Water? Exploring the Myth and Reality

As a coffee enthusiast, I am always interested in learning more about the process of brewing the perfect cup of coffee. One question that has often crossed my mind is whether coffee makers distill water. There seems to be a bit of confusion and conflicting information on this topic, so I decided to dig deeper and explore the myth and reality surrounding coffee makers and water distillation.

The Importance of Water in Brewing Coffee

Before diving into the topic, let’s first understand why water is crucial in the coffee brewing process. Coffee is more than 98% water, so the quality of water used can significantly impact the taste and aroma of the final cup. The composition of water affects the extraction of flavors from the coffee grounds, and any impurities or minerals can alter the taste profile.

What is Water Distillation?

Water distillation is a process that involves boiling water to produce steam, then cooling the steam to capture the condensed water. This process helps remove impurities and minerals, resulting in purified water with a relatively neutral taste and odor.

Understanding Coffee Makers

Coffee makers, commonly known as coffee machines or coffee brewers, are appliances designed to automate the brewing process. They consist of a water container, a heating element, and a brew basket where you place the coffee grounds. Most coffee makers rely on a heating element, which heats the water and passes it through the coffee grounds, extracting the flavors and aromas.

Do Coffee Makers Distill Water?

Now, let’s address the main question at hand – do coffee makers distill water? The answer is no, coffee makers do not distill water. While some coffee makers may have built-in filters to remove sediment or impurities, they do not go through the process of water distillation.

Filters in Coffee Makers

Many coffee makers come with inbuilt filters that help improve the quality of water used in brewing. These filters primarily target chlorine, sediments, or other impurities that may be present in tap water. Filtration systems use activated carbon or charcoal to trap these elements, resulting in better-tasting coffee.

It is important to note that these filters are not designed to remove minerals from the water. Minerals such as calcium and magnesium are essential for coffee extraction and contribute to the overall flavor profile. Removing these minerals through distillation would result in bland-tasting coffee.

Mineral Content in Water

Water used in coffee brewing should ideally have the right balance of minerals. The Specialty Coffee Association recommends that water used in coffee should have a particular range of minerals, such as calcium, magnesium, and bicarbonate. These minerals help with flavor extraction and enhance the taste profile of coffee.

Distilled water, on the other hand, is stripped of minerals, making it less suitable for brewing coffee. Without the presence of minerals, the coffee extraction process may be hindered, affecting the taste of the final product.

Effects of Distilled Water on Coffee Makers

Using distilled water in coffee makers can have some adverse effects on the machine itself. Since distilled water lacks minerals, it can cause corrosion or damage to the internal components of the coffee maker. Over time, this can lead to malfunctions or even render the coffee maker unusable.

Choosing the Right Water for Coffee Making

While coffee makers do not distill water, it is essential to consider the type of water you use for brewing your coffee. Tap water can vary significantly in quality and taste depending on your location. If you find that your tap water has a strong odor or taste, it is recommended to use filtered or bottled water to eliminate any unpleasant flavor notes.

Filtering Tap Water

If your tap water has a chlorine taste, you can use various filtering methods to improve its quality. Faucet filters, pour-over pitchers with built-in filters, or even a simple charcoal filter attachment can effectively remove chlorine and sediment from tap water. This results in a cleaner and more palatable water for brewing coffee.

Natural Mineral Water

Another option that many coffee enthusiasts consider is using natural mineral water for brewing coffee. Natural mineral water, often sourced from underground springs, contains a balanced amount of minerals that can enhance the flavor profile of coffee. However, it is essential to understand the mineral composition of the water to avoid any unwanted flavor profiles.

Personal Preference

Ultimately, the choice of water for brewing coffee comes down to personal preference. Some individuals may enjoy the taste of their tap water, while others may prefer using filtered or bottled water. Experimenting with different water sources can help you find the perfect balance and tailor your coffee brewing experience to suit your taste buds.


In conclusion, coffee makers do not distill water. While they may come equipped with filters to remove impurities, the water used in coffee brewing should still retain the necessary minerals for flavor extraction. Distilled water, which lacks minerals, is not recommended for use in coffee makers as it may affect the taste of the final cup and potentially damage the machine over time. Whether you choose tap water, filtered water, or natural mineral water, finding the right balance is essential for brewing the perfect cup of coffee.
