Mineral water structure

The Craft · Water Philosophy

Water is not
a neutral.

It is an ingredient.

The problem with generic mixers.

Every premium distillery in the world spends decades perfecting the water used in production. They map aquifers, measure mineral composition to parts per billion, test each batch against sensory panels.

Then, when that spirit reaches a bar or dining table, it is served alongside a mixer that was designed for maximum shelf appeal — sweet, aggressive, full of flavour of its own.

The result is not a partnership. It is a competition. The mixer obliterates what the distillery spent years building.

We built Blenders International because we believed the companion to a great spirit deserved the same care as the spirit itself. No more than that. Exactly that.

Mineral structure explained.

Water is never just H₂O. The dissolved minerals — calcium, magnesium, sodium, bicarbonate — each interact with the flavour compounds in a spirit differently.

High calcium

Increases perceived bitterness. Competes with the fruity esters in a Speyside.

High sodium

Adds a subtle metallic edge at concentrations above 30 mg/L. Detectable but rarely attributed to the water.

High magnesium

Adds a slight astringency. Not always unpleasant, but not neutral.

High TDS broadly

Creates what blenders call "flat" dilution — the spirit's aromatic top notes are dampened by the mineral weight.

Plezure's TDS below 50 mg/L is not an arbitrary number. It is the threshold below which mineral interference becomes indetectable in blind tasting panels — the point at which the water is genuinely neutral.


03 / 04

The science of carbonation.

Carbonation is not just texture. CO₂ dissolved in water reacts to form carbonic acid, which lowers pH slightly — and that pH drop affects how the spirit's aroma compounds volatilise in the glass.

At high carbonation levels (above 3.5 g/L CO₂), the aggressive bubbles push volatile aromatic compounds off the surface of the liquid too fast. The nose of the spirit becomes one-dimensional — you get the loudest top notes and nothing else.

Plezure's micro-carbonation at 2.2–2.4 g/L creates bubbles small enough not to disrupt the surface, but active enough to carry the heavier, more complex aromatic molecules upward — the ones that represent the mid-palate and finish complexity of a great whisky.

The result: a diluted dram that is more expressive than the same dram diluted with still water, and far more expressive than one diluted with standard sparkling water.

The Blenders approach.

Every Blenders product begins with a spirit category brief, not a water spec. We ask: what does this spirit category need from its companion? What should a perfect pour of this spirit taste and feel like?

Only then do we work backwards — what TDS allows a whisky like this to unfurl? What carbonation level serves a London dry gin without overriding its botanicals? What pH is right for an aged rum?

We test against the actual spirits with trained sensory panels. We iterate batches until the panel agrees that the companion does what it should: elevate what it's poured with. Never compete. Always complete.

"Great spirits deserve a considered companion."
