FAQ

No, under no circumstances. Merely because the name is identical, this product does not have drinking water quality, since it is usually produced for technical purposes by chemical demineralisation or low-temperature distillation. Since pure water is an extremely strong solvent, during long storage in inferior plastic containers it dissolves harmful plasticisers such as phthalates or bisphenol A out of the walls of the canisters.

In the end, with this water you are taking in a chemically burdened concentrate of plastic residues.

This is a very important question. The answer is, only in glass or stainless steel. The choice of the right container is decisive. Use only vessels of glass or high-quality stainless steel and consistently avoid plastic. Since distilled water, because of its extreme purity, has a strong urge to take up substances from its surroundings, it would interact chemically with plastic containers and actively dissolve plasticisers, microplastics and hormonally active substances such as bisphenol A, BPA, out of the plastic containers.

Glass and high-quality stainless steel, by contrast, are inert, that is, they release no particles and guarantee that your water remains as pure as when it left the still.

Yes. The Confederation authorises distilling apparatus with a capacity of three litres or more individually, and the Ars Aquae still exceeds this limit. The authorisation is granted by the Federal Office for Customs and Border Security BAZG under Article 7 of the Alcohol Act.

The Association prepares the application, provides the documents on the apparatus and accompanies you through the procedure. You can read more in the Terms under Licence and Authorisation.

That is a remarkable process. When distilled water freezes, crystal-clear ice forms. Freezing shows visually how pure this water really is. Ice cubes made from it become as clear as glass. Since no gases or minerals are trapped within, they crystallise perfectly without clouding. The purity is fully preserved on thawing. At the end of this round of questions we would like to let you know that, should you have any further questions, simply write to us. We shall be glad to answer your questions.

Yes, animals usually possess a far finer instinct for the quality of their food than humans and instinctively prefer purer water. Numerous pet owners observe that dogs and cats prefer distilled water to ordinary tap water as soon as they have the choice. This preference underlines the biological acceptance of pure water as the optimal means of hydration, for the animal organism too.

Unfortunately, hardly anywhere. In fact there are scarcely any suppliers who explicitly offer distilled water in retail as drinking water fit for enjoyment. Since the misconception that distilled water is hazardous to health still often prevails among the general public, there is simply no market for economic distribution. Moreover, production and logistics in food quality would be so elaborate that the prices for bottled water would be justifiable neither ecologically nor economically.

Yes, it is even highly recommended. Cooking with distilled water is highly recommended and acts as a true turbo for enjoyment. Whether soups, hot drinks or fine sauces, everything dissolved in water gains greatly in aroma. Since distilled water brings no mineral load of its own, it has a considerably higher dissolving power for natural flavourings. The fine nuances of your ingredients are thus extracted more intensely and come into their own unadulterated.

No. Tap water contains far fewer minerals than most people assume. In Switzerland, Germany and Austria it averages 20 to 100 milligrams of calcium per litre. Anyone wishing to cover the recommended daily requirement of 1,000 milligrams through water alone would have to drink 10 to 50 litres a day. For potassium it would be 400 to 2,000 litres.

You obtain your minerals from food, from vegetables, fruit and wholegrains. Water is a solvent and a means of transport, not a supplier of nutrients.

Yes, to around 99.9 per cent. That is what the overview on our Comparison page shows for all three groups of substances. They remain with the other residues in the evaporation flask while the water rises as pure steam.

A common meter for dissolved substances, the TDS meter, does not detect these substances. It measures only the electrical conductivity of the water, that is, minerals such as calcium or magnesium. PFAS, hormones and pharmaceutical residues remain silent to this device. Distillation nonetheless separates them from the water, whether or not a device displays them.

Yes, it is even highly recommended. Before the industrial revolution, rainwater was regarded as the purest source of water and offered ideal conditions for plant growth. In this tradition, distilled water is today the perfect choice for your plants. Since it is free of lime, the fine pores of the root hairs remain open. The plants can thus take up the nutrients in the soil even more efficiently.

No, absolutely not. This is one of the most frequently discussed questions, and I would like to be very clear here. Trust in the power of food, for that is where minerals belong. The aim is an empty means of transport for cleansing the body. Minerals belong in organic form in food, fruit, vegetables, not in water. Remember that if you artificially add salts to it, it loses its hunger for dissolving.

Much softer and more neutral than any ordinary water. This is unfamiliar to many people, since they do not know, or rather have never been able to taste, how highly pure water tastes. How would they? The taste of distilled water is often described as softer and more neutral than that of ordinary water. Since it is entirely free of minerals, chlorine residues, lime and chemical additives, many people experience the feel in the mouth as especially pure and gentle.

While the first sip may at first seem unfamiliar because accompanying substances are absent, the taste buds quickly recalibrate. Over time they perceive the clarity of the water quite consciously, as your senses are led back to the absolute zero point of neutrality, attainable only in this way.

Great fear and no technology? It is a justified question why this knowledge has not long since become standard. The main reason is purely practical. Until a few years ago it was technically hardly possible to produce water of this quality in one's own kitchen, since the devices were expensive, loud and designed primarily for laboratories. Today the tide has turned. Modern stills have become affordable and optimised for household use.

That this knowledge is only now slowly becoming popular is also due to old myths from times when distilled water was associated only with car batteries or horror stories. As with many health concepts, it takes time for the experience of users to overtake the old dogmas.

Ideally, drink it as warm as possible, like freshly brewed tea, at 50 to 60 degrees. Drinking it warm or almost hot increases its enormous dissolving power even further, because water dissolves better when it is hot. Anyone who has ever cleaned a greasy baking tray with cold and with hot water knows this. Hot water has a lower density and can take up and dissolve even more than cold water.

Drunk cool, it remains just as pure. Choose the temperature according to your enjoyment.

Yes, absolutely. The quantity of distilled water you should drink corresponds exactly to the general recommendations for healthy hydration. The guideline for healthy adults is around 1.5 to 2.5 litres a day, your individual need depending on activity, climate and diet. What matters is a mineral-rich diet of wholegrain products, vegetables and proteins, since water was never the main source of nutrients anyway.

So-called hyponatraemia, a deficiency of sodium in the blood, arises not from the purity of the water but from an excessive quantity drunk in too short a time, which, however, occurs almost only in extreme athletes or under extreme conditions.
