STRUCTURED WATER FOR BETTER COFFEE? PROVE IT !
“We energise your water with ultra-low frequency waves”… science or marketing poetry?
Let’s look at what physics and chemistry actually tell us 👇
1. Ultra-low frequency vs molecular vibrations
Molecules vibrate in the infrared or microwave range—billions to trillions of hertz.
“Ultra-low frequency” means only hundreds or thousands of hertz.
That gap is enormous: such slow fields cannot excite vibrational modes of water or aroma molecules. No meaningful “vibrational energising” can occur.
2. “Anti-oxidising energy” isn’t a scientific concept
Oxidation and reduction involve electron transfer. To make something “antioxidant”, you need:
• real reducing agents (vitamin C, polyphenols, sulfites),
• an electrochemical process (electrolysis, applied potential),
• or removal of oxidants like oxygen.
Weak low-frequency EM fields do not add electrons, change oxidation states, or generate some new “anti-oxidising energy”. That phrase has no standing in redox chemistry.
3. “Promoting molecular binding” and structured water
Liquid water is a fast-fluctuating hydrogen-bond network; bonds form and break in picoseconds.
A weak external field might orient molecules momentarily, but any effect vanishes as soon as the field stops.
There is no robust evidence that such treatments create stable, long-lasting “structured” or “more binding” water.
What actually affects your beverage
For coffee and other drinks, the variables that matter are measurable and ordinary:
• ionic composition (Ca²⁺, Mg²⁺, HCO₃⁻),
• TDS and pH,
• temperature, contact time, grind size, roast profile.
These parameters truly influence extraction and flavour—no need for mystical fields.
Red flags in water-tech marketing
• Vague terms: energising, structuring, memory, anti-oxidising energy.
• Lack of numbers: no frequency, no field strength, no ion analysis.
• No independent data: no redox measurements, no chemical assays, no blinded sensory tests.
If it sounds like sci-fi, ask for data—not adjectives.
