The Still Behind the Door: UK Bars That Make Their Own House Spirits

There is a small copper still behind a door in a growing number of UK cocktail bars. It is not there for decoration. It is there because the owners have decided that the house spirit should actually be made in the house.

In 2026, that still feels like the next stage of the UK craft-spirits story. The first wave was distilleries selling bottles. The second was bars buying those bottles and telling the story. The third is bars making their own spirits, then serving them in drinks you cannot order anywhere else.

From infusion to distillation

Let us separate two things that often get muddled. A house infusion is a spirit — usually vodka, gin or rum — left to sit with fruit, herbs or spices, then strained. A house distillate is a spirit that has been redistilled on site, usually from a neutral base, with botanicals or other ingredients in the still.

The difference matters. An infusion adds flavour. A distillation changes the spirit. It can make it softer, drier, more integrated, or more precise. It also requires a distiller’s licence, duty arrangements, space, ventilation and someone who knows what they are doing.

‘People think because we have a still behind the bar we can make anything,’ says Ruth Calder, co-owner of The Copper Door in Bristol. ‘You can make a lot. But you need a licence, you need to keep records, and you need to be consistent. A cocktail bar lives on consistency.’

What makes it ‘house’?

The Copper Door makes a house gin called Door No. 1. It is redistilled from a neutral grain spirit with juniper, coriander, orris, grapefruit peel and a small amount of locally grown rosemary. It is not a flavoured vodka. It is a proper distilled gin, made in batches of around 80 bottles.

In Manchester, Holloway & Sons takes a different approach. It buys a base rum and redistills it with cassia, ginger, orange peel and a little demerara sugar to make a house spiced rum. The result is lighter and drier than most commercial spiced rums, with less vanilla and more pepper.

And in Edinburgh, The Ledger makes house liqueurs: a heather honey liqueur, a bitter orange liqueur and a small-batch coffee liqueur. The still is tiny — 50 litres — but it gives the bar a set of ingredients that no other bar has.

What to order

The first question to ask is simple: ‘Is this distilled here or infused here?’ Neither answer is bad. An infusion can be excellent. But if you are paying a premium for a house spirit, you should know which one you are getting.

At The Copper Door, order a Door No. 1 martini with a lemon twist. The gin is soft enough that you can taste the rosemary on the finish. At Holloway & Sons, ask for the house spiced rum in a daiquiri — it sounds wrong, but the dry spice works with lime. At The Ledger, order the heather honey liqueur over ice with a soda back. It is sweet, but the smoke from the honey comes through.

‘Do not order a house distillate in a drink that hides it,’ Calder says. ‘If you are going to make a spirit in-house, put it in a drink where you can taste it.’

The economics

A small still is not cheap. A 50-litre copper pot still can cost £10,000 to £30,000 before you have paid for installation, licensing, duty and staff time. A 200-litre still costs more. Then there is the space, the ventilation, the cleaning, the record-keeping and the fact that someone has to be trained to run it.

So why do it? Three reasons. First, differentiation: a house gin or rum gives a bar a drink that no competitor can copy exactly. Second, margin: a house cocktail made with a house spirit can carry a better margin than one made with a branded bottle. Third, story: people like the idea that the spirit in their glass was made a few metres away.

But it does not work for every bar. If you sell 40 cocktails a night and half of them are espresso martinis, you probably do not need a still. If you have a strong identity, a loyal crowd and a bar team that wants to experiment, it can make sense.

Is this the next stage?

Probably, but not in the way the optimists think. Not every bar will become a distillery. Most will keep buying bottles and making infusions. But the bars that do go further are changing what a cocktail bar can be: part hospitality, part production, part shop window for UK craft spirits.

That is the interesting shift. The bar is no longer just the last step in the chain. It is becoming a distillery with seats. And for drinkers, that means one thing: more house spirits to taste, more questions to ask, and more reasons to sit at the bar rather than take a table.
