HThe 10 cities with the best tasting tap water at a glance 

What cities have the best tasting tap water in the world?

1. Zermatt, Switzerland 

Nestled in the Swiss Alps, Zermatt's tap water is as pure as it gets. The water comes directly from ancient glaciers, and minimal treatment preserves its natural minerals, giving it a refreshing, crisp taste. Water quality note: PFAS have been detected in some Swiss groundwater, which can affect tap water quality.

2. Reykjavik, Iceland

Iceland's water is legendary. Sourced from natural springs and purified geothermally, it's not only safe but has a unique taste that's both clean and slightly sweet. Water quality note: Microplastics are present in Reykjavik's supply, but at levels well below the average found in international studies.

3. Munich, Germany

Germany takes its beer seriously, and good beer needs good water. Munich's tap water comes from the Mangfall Valley, where it's naturally filtered through gravel beds, resulting in a soft, pleasant taste. Water quality note: German drinking water has been screened for PFAS; European studies also suggest microplastics are generally present at low levels.

4. Vancouver, Canada

The rainforests of British Columbia are the starting point for Vancouver's water. It's collected from the Capilano, Seymour and Coquitlam reservoirs, and minimal chlorination doesn't detract from its natural, earthy flavor. Water quality note: Research into filtering microplastics indicates their presence in the wider environment, including some water sources.

5. Melbourne, Australia

Melbourne's water is sourced from protected catchment areas in the Yarra Valley, and it's so good it's often used in barista competitions. The secret? A careful balance of minerals that enhances its taste. Water quality note: PFAS have been detected in parts of Victoria; not all utilities test for PFAS or microplastics.

6. Stockholm, Sweden

Stockholm's water comes from Lake Mälaren. It's so pure that minimal treatment is required, so it keeps its natural taste — one that connoisseurs often describe as "soft." Water quality note: PFAS have been found in low concentrations in Lake Mälaren, and microplastics have been reported in some local sources.

7. Oslo, Norway

The fjords of Norway are more than a stunning sight — they're also the source of Oslo's delicious tap water. It's soft, with a low mineral content, making it a favorite among locals and visitors alike. Water quality note: PFAS have been found in Lake Tyrifjorden, a potential tap water source.

8. Vienna, Austria

Vienna's water travels from Alpine springs through historic Roman-era aqueducts. It's naturally high in calcium and magnesium, which contributes to its renowned taste and quality.

9. New York City, USA

The Big Apple's water is sourced from the Catskill Mountains and is so well-regarded that it's even been bottled and sold. Naturally filtered through limestone, it has a distinctive, smooth taste. Water quality note: Around 50% of New York's public water systems have detected some level of PFAS, and microplastics have been found in NYC tap water.

10. Helsinki, Finland

Finland's capital draws its water from Lake Päijänne. It's so clean that it needs minimal treatment, and the result is water that's pure, refreshing and invigorating.

Which European city has the best tap water?

Europe is home to most of this ranking — and for good reason. Alpine and Nordic geography gives cities access to glacier melt, protected springs and pristine lakes that need very little treatment. If you're looking for the best tap water in Europe, these are the standouts:

• Zermatt (Switzerland) — glacier-fed and mineral-rich, our overall number one. 
• Munich (Germany) — soft, gravel-filtered water from the Mangfall Valley.
• Vienna (Austria) — Alpine spring water carried by centuries-old aqueducts.
• Stockholm (Sweden) and Oslo (Norway) — soft, low-mineral Nordic water.
• Helsinki (Finland) and Reykjavik (Iceland) — some of the cleanest, freshest water on the continent. 

Across most of continental Europe, tap water is strictly regulated and safe to drink straight from the faucet — the main differences come down to taste, hardness and trace contaminants like PFAS, which a good home filter can help reduce.

What makes water taste good? 

The taste of water is shaped by its mineral content and how it's treated. Minerals like calcium and magnesium can enhance flavor, making water taste "softer." High concentrations of iron or sulfur, on the other hand, create unpleasant flavors. Treatment matters too — over-chlorination, for example, can leave a chemical aftertaste.

The connoisseur's perspective

Professional water tasters, much like wine sommeliers, look for balance in mineral content and a clean, pure taste. They tend to prefer water with a neutral pH and no single overpowering element. The best-tasting waters are usually those that are naturally filtered and have a well-rounded mineral profile.

How to get great tasting tap water at home

Not everyone can live in the cities with the best tap water — but you can still transform the taste of your own supply. A good water filter is the key. 

Tappwater's nanotechnology faucet filters remove chlorine and 100+ other substances that can affect taste, odor and health, straight from your tap. Reverse osmosis systems are even more thorough, removing a wider range of contaminants, including dissolved solids that affect taste. 

In conclusion

The cities above have set the standard for delicious tap water, thanks to their pristine sources and careful treatment. But no matter where you live, a good water filter can give you that same pure, refreshing experience every time you turn on the tap.

The journey to the perfect glass of water starts with understanding what's in it. So get to know your water — and don't be afraid to invest in a filtration system that suits your taste and your local supply. Cheers to hydration!
