Aquacode coffee brewing water

Stock update: Aquacode is currently out of stock while we await a fresh delivery. Unfortunately, we don't currently have a confirmed restock date, but we'll make it available again as soon as new stock arrives.

Water makes up roughly 98% of a filter coffee and around 90% of espresso. If your tap water is hard, heavily chlorinated, or mineral-poor, it directly affects extraction: muting acidity, flattening clarity, or creating a chalky finish regardless of how good the coffee is.

Aquacode is a liquid mineral concentrate developed to solve that problem. Each sachet contains deep-sea ionic minerals sourced from below 700 metres in the Pacific Ocean, formulated to a calcium-to-magnesium ratio of 1:2.7. Added to distilled or deionised water, a single sachet produces water that meets SCA brewing standards at 85ppm TDS, enough mineral content for full extraction without the interference of chlorine, bicarbonates, or excessive hardness.

The format is practical. Because the concentrate is liquid rather than powder, it dissolves instantly with a quick mix. The 7-litre 'Barista' sachets are designed to be diluted with 7 litres of pure distilled water (0ppm), though the included dilution chart covers a range of ratios if you want to adjust to taste or brew method. Aquacode has been used in competition by several national Brewers Cup champions and was the designated water for the 2019 World Brewers Cup Champion.

Available in a single sachet, a 3-sachet taster pack, or a box of 12.

Why does water quality matter for coffee?

Water is roughly 98% of a filter coffee and around 90% of espresso, so its mineral content directly shapes extraction. Too little mineral content and the coffee tastes flat and underextracted. Too much hardness or chlorine and it turns chalky or dull, no matter how good the beans are.

Can I use Aquacode with tap water instead of distilled?

Aquacode is designed to be added to distilled or deionised water (0ppm), which gives you a known, repeatable starting point every time. Tap water mineral content varies by area, so mixing Aquacode into it means you're no longer starting from zero, and the final result becomes harder to predict.

How is Aquacode made?

It's extracted from deep-sea water below 700 metres in the Pacific Ocean, off the coast of Taiwan. The water is filtered and concentrated at low temperature with no additives, isolating the calcium and magnesium ions in the 1:2.7 ratio the formula is built around.

What sachet sizes are available?

The 7-litre 'Barista' sachet is sold as a single sachet, a 3-sachet taster pack, or a box of 12, so you can try it before committing to a larger box.

Is Aquacode suitable for espresso as well as filter coffee?

Yes. Water makes up around 90% of espresso and roughly 98% of filter coffee, so the mineral content matters for both. The dilution chart covers a range of ratios if you want to adjust the strength for a specific brew method.

How much brewing water does one sachet make?

One 7-litre sachet, diluted as directed with 7 litres of distilled water, makes 7 litres of brewing water. The dilution chart shows how to adjust that ratio if you want a different strength.
