Can You Use Distilled Water in a Coffee Maker? The Pros and Cons Explored

Coffee is an integral part of many people’s lives. Whether it’s a strong black brew to kick-start your day or a creamy latte to savor during a relaxing afternoon, coffee has the power to energize and comfort. To ensure that your coffee tastes its best, it’s crucial to pay attention to the quality of water you use. Many coffee enthusiasts wonder whether distilled water can be used in a coffee maker. In this article, we will explore the pros and cons of using distilled water in your coffee maker.

Pros of Using Distilled Water

Elimination of Mineral Deposits

One of the primary advantages of using distilled water in a coffee maker is the elimination of mineral deposits. Tap water often contains various minerals, such as calcium and magnesium. Over time, these minerals can accumulate in your coffee maker, leading to clogs and affecting the taste of your coffee. Distilled water, on the other hand, is devoid of minerals, reducing the likelihood of build-up and extending the lifespan of your coffee maker.

Avoiding Unpleasant Odors and Tastes

Tap water sometimes carries odors or tastes linked to chlorine, sulfur, or other chemicals used in water treatment. When you brew coffee using untreated tap water, these unpleasant flavors can affect the taste of your favorite beverage. By using distilled water, you eliminate the risk of introducing unwanted odors or tastes into your coffee, ensuring a pure and enjoyable cup every time.

Consistency of Flavor

Coffee flavor is highly influenced by the quality and consistency of water used during brewing. Since distilled water lacks minerals and impurities, it provides a neutral base for brewing coffee. This neutrality ensures that the flavors and aromas of your coffee beans shine through, allowing you to enjoy a consistent and true representation of your chosen blend.

Cons of Using Distilled Water

Lack of Minerals

Although the absence of minerals in distilled water can be beneficial to your coffee maker and the flavor of your coffee, it also means that you are missing out on important minerals that can be obtained from water. Some minerals found in tap water, such as calcium and magnesium, can contribute to your overall daily intake. Therefore, consistently using distilled water may lead to a slight reduction in mineral consumption. However, this can be easily balanced through a balanced diet containing mineral-rich foods.

Potential for Corrosion

Using distilled water in a coffee maker can potentially result in corrosion due to its lack of minerals. Coffee makers typically contain metal components, and without minerals present in the water, these metals may be more susceptible to corrosion over time. However, it is important to note that this risk is minimal and often associated with prolonged and excessive use of distilled water without regular cleaning and maintenance of the coffee maker.

Extra Cost and Effort

Distilled water is not as readily available as tap water and usually needs to be purchased or obtained through home distillation processes. This may add an additional cost to your coffee brewing routine. Additionally, the process of purchasing or distilling water requires extra effort and time compared to using tap water directly from the faucet. Considering these factors, you may need to decide whether the benefits of using distilled water outweigh the added expense and effort.


Using distilled water in a coffee maker has its advantages and disadvantages. By using distilled water, you can eliminate mineral deposits, avoid unpleasant odors and tastes, and enjoy a consistent flavor profile. However, it is important to be mindful of the lack of minerals in distilled water, the potential for corrosion, and the additional cost and effort required. Ultimately, the choice between using distilled water or tap water in your coffee maker depends on your personal preferences and priorities. Whichever option you choose, remember that water quality plays a significant role in the taste and overall experience of your coffee.
