Why does a distillery need specialist insurance treatment?

A distillery combines several of the exposures underwriters find hardest to price into a single business — and it does so in a sector booming faster than the insurance market has adapted to. Distilling spirits means producing and storing large volumes of highly flammable, high-strength alcohol; it means accumulating enormous value in slowly maturing stock that can take years to become saleable; and it means carrying a spirits-duty liability to HMRC that can exceed the physical value of the stock itself. Layer on product-contamination risk, expensive bespoke stills, and a stream of visitors on tours around a hazardous process, and you have a business that generalist insurers routinely underprice, exclude, or decline outright.

This is the territory Miller & Partner works in. As a specialist broker for adverse and hard-to-place risks, we place cover for spirit producers the standard market finds difficult — including distilleries that have been refused cover elsewhere or hit with a fire-driven renewal shock. This guide explains why fire and explosion is the exposure that defines a distillery, why maturing stock is the hardest thing to insure correctly, how spirits duty creates a hidden liability, and how to present a distillery so specialist underwriters price it fairly. Our guides to craft brewery insurance and brewery insurance cover the closest adjacent drinks-production sectors.

What must a distillery policy include that a standard policy won't?

Distilleries are often sold a generic commercial or manufacturing package, and it's rarely the right shape. A standard policy is built for a low-hazard workshop with ordinary stock — not for a business making and storing high-strength flammable spirit, sitting on years of maturing casks, and carrying a duty liability to HMRC. The gaps show up in exactly the places a distillery is most exposed: fire and explosion rating, how stock is valued and insured, duty exposure, and the length of the business-interruption indemnity period. The comparison below shows where a standard policy falls short and what a specialist distillery programme does differently.

Why is fire and explosion the exposure that defines a distillery?

If one thing defines distillery insurance, it is fire and explosion. Distilling concentrates ethanol to high strength, and cask-strength spirit at around 70% ABV has a flash point near 23°C — close to room temperature — so it readily gives off vapour that forms a flammable, potentially explosive atmosphere. The distillation, fermentation and maturation stages all create this hazard, and even the "angels' share" — spirit evaporating through cask staves in the warehouse — raises the concentration of flammable vapour around thousands of barrels. Grain milling adds combustible dust. In short, a distillery contains, by design, all three ingredients of an explosion: fuel, vapour and potential ignition sources.

The sector's history makes the point. The Cheapside Street bonded warehouse fire in Glasgow in 1960 took a week to extinguish and claimed the lives of 19 fire-service personnel; the Langley gin distillery fire in 2012 drew 100 firefighters. These are catastrophic, total-loss events, and they are why property and fire underwriters scrutinise a distillery so closely. Compliance with the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) and ATEX hazardous-area classification — proper zoning, explosion-rated equipment, ignition-source control, ventilation, fire detection and physical separation of the still house and warehouse — is not just a legal duty under the HSE's regime; it is the single biggest thing that determines whether, and at what price, a distillery can be insured at all. The high-risk public liability dimension runs alongside it.

Why is maturing stock the hardest thing to insure correctly?

A distillery's stock is unlike almost any other manufacturer's. Whisky must mature for at least three years before it can legally be called whisky, and many spirits age far longer — so a distillery accumulates, year on year, an ever-growing inventory of casks that represent enormous locked-up value but cannot be sold yet. This creates two insurance problems at once. First, the value is constantly rising, which makes it dangerously easy to underinsure: stock insured at last year's figure, or at production cost rather than current value, leaves a huge gap. Second, the stock is irreplaceable in the short term — if a warehouse of ten-year-old casks burns, you cannot simply buy or make more; the aged stock, and the future revenue it represented, is gone for a decade.

That's why specialist insurers treat spirits stock differently. Most require it to be insured as a separate item from general stock, reflecting its high theft and duty value, and they want to see how it's valued, stored and protected. Getting the sum insured right — reviewed annually, reflecting current value and duty — is the single most important number in a distillery's policy, because underinsurance here triggers the condition of average and cuts the claim proportionately at the worst possible moment. Alongside it, the way maturing stock drives the length of your business interruption cover is covered below.

How does spirits duty create a hidden insurance exposure?

Spirits carry some of the highest excise duty of any product in the UK, and the way that duty works creates an exposure most distillers underestimate. While spirits sit in an approved bonded warehouse, the duty is suspended — not yet payable. But the duty doesn't disappear; it hangs over the stock. If duty-suspended spirit is lost, stolen or diverted from the warehouse, the duty point can crystallise and the distiller becomes liable to pay HMRC the duty on it — on top of losing the physical stock. Because duty on spirits is so high, that duty liability can rival or exceed the production value of the stock itself.

For insurance, this means a distillery's true exposure on its stock is often much larger than the physical value suggests — and a policy that insures only the material value of the spirit leaves the duty exposure uncovered. A well-structured distillery programme addresses the duty dimension explicitly, and the distiller's Alcoholic Products Producer Approval (APPA) — HMRC's producer authorisation that replaced the old distiller's licence in February 2025 — together with warehouse approval and security, sits at the centre of how that risk is managed and underwritten. Getting the duty exposure understood and reflected in the sums insured is one of the most valuable, and most overlooked, parts of insuring a distillery properly.

What insurance covers does a distillery need?

A distillery programme is genuinely combined, and the covers must be structured together so a single event — a fire will usually hit property, stock, duty and income at once — doesn't fall between sections. The core structure looks like this:

Property, plant & stills (fire & explosion)

Buildings, stills and equipment against fire, explosion and damage — the core, and the hardest, cover to place. Bespoke stills carry long reinstatement lead times that must be reflected.

Spirits stock (separate item, with duty)

Maturing and finished stock insured as a separate item at current value including duty exposure — reviewed annually to avoid underinsurance.

Business interruption (long indemnity)

Lost income after an insured event, with a 24–36 month (or longer) indemnity period for the maturation cycle. See business interruption insurance.

Public & products liability

Third-party injury and property damage — visitors and tours — plus products liability for a consumable spirit, with product recall for contamination. See high-risk public liability.

Employers' liability, transit & management liability

Legally required EL for staff working around a hazardous process; goods-in-transit and cargo for UK and export shipments; and directors' & officers' / management liability for the business's leadership.

Why are product liability and contamination a core exposure?

A distillery makes a consumable product that people ingest, which puts products liability at the centre of the risk. If a spirit is contaminated, mislabelled as to strength, or improperly distilled — badly made spirit can contain harmful levels of methanol — the consequences range from illness claims to a full product recall. Even without harm, a labelling or quality failure can force a costly recall and destroy hard-won brand trust. Products liability and product recall insurance respond to these events, covering third-party injury, the cost of withdrawing affected product, and the associated defence and reputation-management costs.

Selling to retailers, exporting, or supplying bars and festivals typically makes products liability a contractual requirement, not just a prudent cover — large buyers won't stock a spirit without it. The exposure grows with distribution: the wider a spirit is sold, the larger a recall becomes. A distillery that can evidence robust quality control, batch traceability and testing is both reducing the risk of a contamination event and presenting a stronger risk to underwriters. This is a core cover for any distillery moving product beyond its own door, and it dovetails with the wider drinks-production considerations in our brewery insurance guide.

How do tours, tastings and visitors change your cover?

Many distilleries have become visitor destinations — tours, tastings, shops and events are now a core revenue stream, especially for gin and craft operations. But bringing members of the public onto a working production site, around stills, hazardous areas and high-proof spirit, sharply increases the public liability exposure. A visitor slipping, being injured near equipment, or being affected by an incident in a hazardous area is a live claim, and the presence of the public also raises the stakes of any fire or explosion event. Serving spirits on-site adds a hospitality and liquor-liability dimension on top.

For insurance, this means your public liability has to be sized for genuine footfall around a hazardous process, and underwriters will want to see how visitors are managed — controlled tour routes, barriers around hazardous areas, trained guides, and clear separation between the public and the working plant. A distillery that runs tours as an afterthought, without a visitor risk assessment, presents a materially worse risk than one that manages footfall properly. Getting the visitor exposure disclosed and well-controlled is part of presenting a complete, credible risk that a specialist market will price fairly.

Why does business interruption need a long indemnity period?

Business interruption is where distilleries most often get their cover dangerously wrong, and the reason is the maturation cycle. A standard BI policy carries a 12-month indemnity period — the maximum time the insurer will pay for lost income after an insured event. For most businesses that's enough to rebuild and recover. For a distillery it can be nowhere near enough: if a fire destroys your stills and maturing stock, twelve months won't rebuild a bespoke still, won't replace years of aging inventory, and won't restore the revenue stream that depended on stock that took a decade to create. You could be trading at a fraction of capacity for years.

That's why specialist distillery programmes recommend a 24–36 month indemnity period, and often longer for whisky operations with long maturation tails. The indemnity period has to reflect how long it would realistically take to return to the earnings you'd have had — including the lead time on replacement stills and the years of lost maturation. Getting this number right is as important as the sum insured itself: a generous property limit paired with a too-short indemnity period still leaves the business exposed to exactly the slow, grinding loss a distillery fire produces. Our business interruption insurance guide explains how indemnity periods are set.
