Hey, there, coffee lovers! Are you looking for a way to make your cup of joe even better? Well, I’m here to tell you the answer is filtered water. That’s right – if you’re serious about getting the perfect brew every time, it pays to invest in some quality filtration.

Using tap water full of chlorine and other impurities can damper your java dreams. A good filter system is essential if you want consistently great-tasting coffee. It will remove contaminants like lead and copper and soften hard minerals, negatively affecting flavor and aroma.

This article will examine why filtered water is so important and how it can take your morning cup from average to extraordinary.

Why Filtered Water Is Important When Making Coffee

As a barista, I can tell you that the quality of your water largely determines the quality of your coffee.

While regular tap water is fine for daily use, it’s not ideal when making coffee. This is because tap water contains impurities like chlorine, fluoride, and other chemicals. If these contaminants are present at high levels, they will affect the flavor of your brew.

A reverse osmosis filter or a whole house water softener system will remove almost all the harmful elements from your drinking water – leaving you with clean, pure-tasting espresso shots every time! Or if you don’t have the cash to splash on a more expensive system, even something as simple as a pitcher filter can help improve the taste of your drink.

The result? Smooth-tasting lattes without any bitter aftertaste or funky odor.

It takes just a few extra steps to ensure your cup of joe tastes great – but trust me, it’s worth it!

Advantages Of Using Filtered Water For Coffee

When making coffee, using filtered water is one of the best things you can do. A whole-house water filter, a water softener, or a reverse osmosis system will ensure that your brew has fewer impurities and tastes much better than tap water.


If your water tastes bad, it’s easy to see how this could impact the taste of your coffee.

Using filtered water for coffee can promote better flavor extraction from the coffee grounds. Too many minerals and other compounds in tap water can interfere with extraction, resulting in weak or sour-tasting coffee.

Other contaminants like chlorine can also affect the taste of your coffee. Chlorine is used to disinfect water and is safe to drink, but it can leave an unpleasant taste in your coffee.

By using softened and filtered water, you can ensure that your coffee is full-bodied and rich in flavor.

Less scale in your machine

Water treated by a softener has fewer minerals than tap water, which can help reduce the potential for scale buildup in your coffee maker. This can help your machine last longer and work more efficiently.

Disadvantages Of Using Filtered Water For Coffee

While filtered water certainly has its advantages, it’s not without its drawbacks.

Cost & Maintenance.

For starters, if you’re using hard water in your coffee machine, a whole-house water softener may be necessary to reduce the limescale buildup that often occurs with this type of water. This can get expensive and time-consuming.

Even with the less expensive option, a water filter pitcher, you’ll still need to fork out for regular filter replacements.

May Not Produce The Tatse You’re Looking For

For example, reverse osmosis filters may remove too many minerals, resulting in water that doesn’t extract the full flavor of the coffee. To avoid this, use a filter designed to leave in some of the minerals necessary for a good cup of coffee.

How To Choose The Right Type Of Filter For Coffee

When choosing the right type of filter for your coffee, there are a few things you’ll need to consider.

Do You Need A Water Softener?

First and foremost, you should consider what kind of water is coming from your tap – hard or soft? If you have hard water, you will need to invest in a water softener to use in combination with your filter.

Softeners are expensive and must be installed at your house’s entry point. However, they’ll provide you with soft water throughout your home. You’ll see improvements in scale build-up, your water will taste better, and you’re appliances will last longer too.

Consider a Coffee Machine With A Built In Filter

Consider investing in a coffee machine with a built-in filter like the Jura Z6. This will save you time and is more convenient, especially if you’re only using filtered water for coffee and not for your drinking water.


Beyond that, the cost is another factor worth considering; some filters can get quite pricey depending on their size and capabilities. But remember: investing in quality filtration now could save you money down the road when it comes time to descale or repair your machine due to limescale buildup!

And finally, make sure to check how often each filter needs changing; this information should be readily available from manufacturers or retailers. Try calculating the cost of replacements per year, so you don’t get any nasty surprises.


As a barista, I’m often asked about the importance of using filtered water to make coffee. My answer is always that it’s essential! Using filtered water ensures that your cup of joe will be full of flavor and free from impurities and pollutants.

The advantages are numerous: you’ll get better-tasting coffee with fewer contaminants, you can control how much minerals are in the water and thus adjust the taste, plus filtered water helps keep your machine clean and running smoothly.

Ultimately, having access to high-quality filtered water makes all the difference in producing delicious specialty coffees at home or in a professional setting. So don’t skimp on this vital step – invest in a reliable filter today so you can enjoy great-tasting java tomorrow!
