Distillery CO₂ capture

Distillery CO₂ capture — capture the wash, not just the spirit

Cork & Capture is a portable CO₂ recovery system for gin, whisky, rum and vodka distilleries. Capture biogenic CO₂ from wash fermentation, eliminate purchased CO₂ for blanketing and bottling, and turn a vented gas into Verra-certified biogenic carbon credits.

The CO₂ problem

Distilleries are the forgotten CO₂ producers

Distillation gets the spotlight, but the CO₂ comes from fermentation. Wash fermentation in a distillery produces the same biogenic CO₂ as a brewery — and most of it is vented through the washback roof while the distillery pays for bulk CO₂ to blanket spirit, dose tonics or counter-pressure fill RTDs.

Wash fermentation = brewery-scale CO₂

Whether you make grain neutral spirit, rum or single malt, your washback releases roughly the same biogenic CO₂ per litre as a brewery — and almost all of it is currently lost.

Bought-in CO₂ for blanketing & RTDs

Distilleries still buy bulk CO₂ for tank blanketing, bottling, RTD canning and gin/tonic packaging. Capturing your own closes that loop on site.

Sustainability scrutiny is rising

Premium-spirits buyers — supermarket category, on-trade, export — increasingly demand a Scope 1 plan. CO₂ capture is one of the few interventions that delivers a measurable reduction.

The solution

Modular CO₂ capture system, sized for a distillery

A portable, modular CO₂ recovery system that installs directly on your washbacks. We capture the biogenic CO₂ produced during wash fermentation, purify it to beverage-grade, and store it on site for reuse or onward sale.

Carbon capture at the fermentation tank — installs on existing washbacks

No new fermentation kit, no rebuilt vessels. We deliver carbon capture at the fermentation tank — connecting to your existing washbacks, capturing the CO₂ as it is produced, and routing it to a compact on-site purification and storage skid.

Beverage-grade output

Purified to ISBT beverage-grade standards. Suitable for inert blanketing of finished spirit, gin & tonic packaging, RTD canning and bottling counter-pressure.

Replaces purchased CO₂

Cuts the bulk CO₂ contract used for blanketing and packaging — and removes the supply-chain risk that comes with it. Your fermentation already produces the gas you need.

Surplus → revenue

What you do not use is collected by us and either resold via our facilitated network (10% fee) or permanently sequestered. Sequestered tonnes generate biogenic carbon credits with revenue shared back to you.

Subscription, not capex

A monthly subscription replaces a six-figure capital purchase. We handle install, service, gas certification and removal. You get the output without the engineering team.

Year-round operation

Distilleries that ferment year-round get the most out of the system. We size capacity to your annual wash volume rather than a peak day.

Sustainability

A net-zero distillery story your buyers will actually quote

From premium-spirits supermarket buyers to export agents, the question is the same: what is your Scope 1 plan? Capturing biogenic CO₂ is one of the most defensible, audit-ready answers a distillery can give.

Scope 1 reduction

Vented biogenic CO₂ becomes captured biogenic CO₂. Purchased fossil CO₂ falls off the procurement spend. Both moves show up cleanly in your Scope 1 / Scope 3 footprint.

Verra-certified credits

Permanently sequestered surplus CO₂ generates Verra-certified biogenic carbon credits. Real removals, with real paperwork, that survive third-party audit.

Buyer-ready evidence

Capture volumes, purity certificates and credit registrations are provided in formats that drop into supermarket sustainability questionnaires, B Corp submissions and export buyer packs.

FAQ

CO₂ recovery for distilleries — common questions

Can a distillery capture its own CO₂?

Yes. The CO₂ comes from wash fermentation — the same process that happens in a brewery. A portable CO₂ recovery system installed on your washbacks captures that gas, purifies it to beverage-grade, and stores it on site for blanketing, packaging, RTD canning or onward sale.

How much CO₂ does a distillery produce?

Roughly 4 kg of CO₂ per 100 litres of wash fermented — broadly equivalent to a brewery on a per-litre basis. A mid-sized distillery producing several million litres of wash a year is venting tens of tonnes of biogenic CO₂.

What can captured CO₂ be used for in a distillery?

Inert blanketing of finished spirit, tank purging, bottling and counter-pressure filling, gin & tonic and RTD canning, and any other beverage-grade CO₂ application currently served by a bulk CO₂ contract.

How does this affect Scope 1 emissions?

Capturing fermentation CO₂ that would otherwise vent — and replacing purchased fossil CO₂ — produces a measurable, audit-ready reduction in Scope 1 (and Scope 3) emissions. We provide the data in the format buyers and auditors actually want.

Is captured CO₂ safe for spirit packaging?

Yes. Every batch is purified and tested to ISBT beverage-grade standards before it leaves the system. Quality assurance is built into the process.

Can a small craft distillery afford this?

Yes. Cork & Capture is offered on a monthly subscription with no capex. The system is sized to your wash volume, so a small distillery only pays for what it needs. See our commercial terms page for the full breakdown.

Can we earn carbon credits?

Yes. Surplus captured CO₂ that is permanently sequestered generates Verra-certified biogenic carbon credits, with revenue shared back to you. That credit revenue often offsets a meaningful portion of the subscription fee.
