For cafés, roasteries & restaurants

Your cup is mostly water. Make it the right water.

AkVo PRO purifies tap water by reverse osmosis and rebuilds its minerals to the profile coffee and tea need — so your machine stays free of scale and your cup tastes the way the roaster intended.

Our story

Made by baristas, for the bar.

AkVo started behind our own specialty coffee bars. We were baristas running our cafés, and water was our biggest problem: nothing on the market gave us a stable ppm at a running cost that made sense. So we designed the system we needed.

What matters most to us is standardisation and repeatability — the same water, cup after cup, day after day.

01 — The problem

No stable water

Week to week the mineral content of our water changed, and so did our coffee. Cartridges and softeners were expensive to run and still not consistent.

02 — Our own system

Stable ppm, low running costs

So we built our own: reverse osmosis plus precise remineralisation — water with a stable ppm and running costs an independent café can carry.

03 — Liquid minerals

Water we can design

We wanted real influence on our water. AkVo evolved into dosing liquid minerals into pure RO water, so we can design water for café use — not just filter it.

04 — A shared standard

The same water everywhere

Today the same AkVo water can run in every café of a chain, in a roastery’s QC lab and at a green coffee distributor’s cupping table.

One water. One standard.

The same water means talking about the same coffee.

When a green coffee distributor, a roastery and a café brew with exactly the same water, they taste the same coffee. One water is a shared standard that prevents misunderstandings when you discuss and evaluate coffee quality.

Café chains

The same cup in every location — one recipe, one water, no surprises between shops.

Roasteries

Develop profiles and run quality control on reference water — and know your customers brew with it too.

Green coffee distributors

Cup samples on the same water as your clients, so scores and notes mean the same on both sides.

How it works

Strip it back. Build it up. Dial it in.

No ion-exchange resin, no guesswork: the water that reaches your boiler has a composition you chose.

01 — Purify

Reverse osmosis

A high-efficiency membrane removes about 99% of dissolved ions — including the calcium that scales boilers and the excess bicarbonate that dulls acidity.

02 — Rebuild

Remineralisation

Precise hydraulic valves blend back a measured share of minerals from your own water — without changing their natural ratio.

03 — Dial in

Set your TDS

Turn the +PPM− dial to the mineral level you want. Two gauges show pump and system pressure, so you always see it’s working.

Built in

One screw, your mineral level

Every AkVo PRO has a +PPM− screw on the side. Turn it left and more of your own tap-water minerals are blended back into the pure RO water; turn it right for softer water. Two gauges show pump and system pressure, so you always see it’s working.

Mineral modules

Add modules. Build the water your coffee needs.

AkVo PRO can feed one or more mineral dosing modules — magnesium, calcium and buffer — in the configuration your bar needs: one water for espresso and filter, a fuller water for filter only, or separate water for each machine.

    AkVo Minerals · for home & cupping

    A few drops. A different cup.

    Add to demineralised or RO water before brewing — or one drop straight into the cup to taste what minerals do.

    AkVo mineral dropper bottles: Black, Pink, Blue and Clear

    BLACK

    magnesium buffer

    Brightness and acidity — lifts even a dark roast.

    PINK

    sodium buffer

    Softens aroma for a milder, cleaner, smoother cup.

    BLUE

    calcium chloride

    Sweetness and clarity, with fruity notes lifted.

    CLEAR

    potassium buffer

    Neutral and balanced — clarity without muting flavour.

    ESPRESSO

    mineral balance · 50 ml

    Designed especially for espresso — helps prevent corrosion and limescale. 3–5 drops per 500 ml of water.

    Pre-brew 3–5 drops / 0.5 L water · Post-brew 1 drop / cup

    Bottle 50 g · approx. 700 drops · €20 · Set €60 · lasts about 100 L of water, depending on dosing

    Before you start

    The drops need RO or demineralised water.

    AkVo drops are made to rebuild pure water, so start from reverse-osmosis or demineralised water — from any home RO system you like, or distilled/demineralised water from the shop. Don’t add them to tap or mineral water. AkVo doesn’t make home filtration kits; our systems are built for cafés and roasteries.
