How Water Quality Affects the Taste of Coffee and Tea

If you aren’t enjoying your coffee as much as you once did, you may blame your coffee beans. But the real culprit could be your water.

The same is true for tea. Extra minerals and chemicals in your water change how flavors pull from coffee beans or tea leaves.

How Contaminants Influence Coffee and Tea

Water chemistry directly influences the taste of your coffee or tea. Here are some examples:

• Chlorine: If your tap water tastes like chlorine, your coffee or tea may taste like bleach. This strong flavor may also block sweet, floral, or fruity notes.

• Minerals: When your water contains high concentrations of magnesium and calcium, it can affect the flavor and mouthfeel of your coffee. Minerals can also make coffee or tea taste sour or dull.

• Other contaminants: Iron creates a metallic taste, sulfur creates an egg-like smell and taste, and dirt causes an earthy flavor.

What Is the Best Water for Coffee and Tea?

The best water for coffee and tea is clean, chlorine-free filtered water with moderate mineral content (total dissolved solids around 50–150 ppm) and a neutral pH.

It’s best to filter out chlorine and odors, as these instantly ruin any delicate notes in coffee and tea. As for minerals, don’t use distilled water, as your hot beverage will taste flat. Without minerals, coffee and tea extract poorly. That said, if the water is mineral-heavy, coffee can taste chalky. Hard water also damages equipment. Striking the right mineral balance is important.

Best Water Options for Brewing Coffee and Tea

You have several options to maximize the quality of your coffee and tea.

• Filtered tap water can be a budget-friendly option when using a standard carbon filter to target chlorine. Depending on the level of filtration, you can target varying contaminants of concern. However, it won't address hard-water issues.

• Low-mineral bottled water is an easy choice, as you can buy specific commercial brands with ideal natural mineral profiles. For example, having water delivered for a bottom-load cooler means zero setup, but it comes with ongoing costs.

• Remineralized reverse-osmosis (RO) water gives you total control over the exact mineral content. Use RO water, then add mineral packets for greater consistency. Many coffee enthusiasts agree this option helps improve flavor and control. You can pair an RO solution with a water softener if you have hard water.

Consider an RO System to Improve Each Cup

If you’re serious about your coffee and tea, your best bet is an RO filtration system. This option strips out minerals, chlorine, and impurities that alter the delicate flavor profiles of specialty coffee and loose-leaf tea. The most advanced systems offer a remineralization stage. This process yields pure extraction, protects your equipment, and provides consistent taste, cup after cup.

Here are some popular solutions:

• Under-sink tankless systems provide pure, low-TDS (total dissolved solids) water that extracts optimal coffee flavors and prevents scale buildup in your machine. Check out the Brio AQUUS Tankless RO Under Sink Filtration System or the Brio G20-U RO Undersink Filtration System.

• Countertop units are perfect when space is limited. The Brio Q60 provides precise temperature presets, from near-boiling water for tea to cold and sparkling options, without permanent plumbing.

• You can even get all-in-one beverage dispensers, like the Brio Moderna Café Series, which combines 4-stage reverse osmosis filtration with a built-in single-cup capsule brewer and instant hot water taps.
