Shot Glass
A small heavy-based glass holding 25 to 50ml. It is one of the more misunderstood objects on a home bar: useful as a vessel, unreliable as a measure, and responsible for a great many badly balanced cocktails.
Alternatives
Budget Alternative
Small cordial glasses (£2–3): usable for casual service, but often lack durability and consistent volume.
Premium Option
Libbey Heavy Base Shot Glass (£15–20 for set of 12): durable, consistent, and widely used in professional bars.

Usage
Serving spirits neat in small measures, layered shooters, and the odd drink built to be drunk in one. Not for measuring: the UK single is 25ml and the double 50ml, but the glasses sold as shot glasses vary far more widely than that.
What a Shot Actually Is
The UK is unusually precise about this. Licensed premises must serve spirits in measures of 25ml or 35ml, and multiples of those, and the measure has to be stated. Most of England and Wales works to 25ml as a single and 50ml as a double; much of Scotland and Northern Ireland uses 35ml.
The United States has no legal definition at all. A shot there is conventionally 1.5 fluid ounces, roughly 44ml, but it varies by state, bar and pour.
None of which is stamped on the glass in your cupboard. That is the source of most confusion about what a shot glass holds.
Why It Fails as a Measure
The glasses sold as shot glasses run from about 25ml to nearly 60ml, and very few carry a marked line. Two that look identical on a shelf can differ by a third.
That matters more than it sounds. A Daiquiri is 60ml rum, 25ml lime, 15ml syrup, and the whole drink is the ratio between those three. Measure the rum with a glass that turns out to hold 45ml and you have not made a weaker Daiquiri. You have made a sour one, because everything else stayed the same.
A jigger costs a few pounds and is accurate to the millilitre. There is no argument for using a shot glass instead.
The Heavy Base
The thick slab of glass at the bottom is structural, not decorative. Shot glasses are set down hard, and a proportion of their working life involves being struck against a bar top before drinking.
The mass also lowers the centre of gravity, so a small glass on a crowded table is harder to knock over, and it slows warming slightly by keeping the liquid away from the surface it stands on.
It is one of the few pieces of bar glassware genuinely designed around abuse. Which is why they survive in bars that break everything else, and why cheap thin-based ones chip almost immediately.
What Belongs In One
Spirits meant to be drunk quickly and cold: chilled vodka, aquavit, tequila blanco with lime and salt, and the layered shooters that need a narrow bore to keep their bands apart.
What does not belong is anything worth sipping. A good mezcal, an aged rum or a single malt wants a glass with room above the liquid to gather aroma: a Glencairn, a copita or a small rocks glass. Serving a £60 spirit in a vessel designed for slamming wastes most of what you paid for.
Two of the useful marked kind, and a jigger, cover everything a home bar needs.
Pro Tip
For agave spirits, serve chilled water alongside the shot and encourage guests to sip rather than throw back. A proper shot glass allows tequila or mezcal to be appreciated, not endured.
What to Look For
- Clearly defined capacity: consistency matters
- Thick, weighted base: stability and durability
- Smooth rim: comfort on quick sips
- Straight sides: allow layered shots when needed
- Clear glass: visual clarity is part of the experience
Common Mistakes to Avoid
- Confusing shot glasses with jiggers: accuracy suffers
- Using novelty shapes: distort volume perception
- Overfilling: encourages spillage and waste
- Thin glass: breaks quickly under service conditions
- Ignoring regional measure differences: creates inconsistency
Professional Tips
- Do not use it as a jigger. Buy a jigger.
- The thick base is for slamming, not for show.
- Chill for anything drunk cold; leave good spirits at room temperature.
- Check the fill line. Most decorative ones have none.

History & Context
The shot glass emerged alongside standardised measures in the late 19th and early 20th centuries, as bars moved toward consistency and regulation. While its name suggests speed, its real purpose is accuracy: delivering a known quantity of spirit reliably. Despite its association with hurried drinking, the shot glass plays a vital role in tasting culture, particularly for agave spirits and regional traditions where small, neat pours are savoured rather than rushed. In modern bars, it remains an essential tool: simple, honest, and widely misunderstood.
Common Questions
How much does a shot glass hold?
It depends entirely on the glass, which can run from 25ml to nearly 60ml. UK licensed measures are 25ml or 35ml and multiples of those; the US convention is about 44ml with no legal definition. Almost none of that is marked on the glass.
Can I use a shot glass as a jigger?
No. Unmarked glasses vary by a third between designs, and cocktails are built on ratios rather than volumes. Measuring 45ml as 60ml does not weaken a Daiquiri, it sours it. A jigger costs a few pounds and is accurate to the millilitre.
Why do shot glasses have thick bases?
Because they get set down hard, and struck against the bar in some traditions. The mass is structural, and it lowers the centre of gravity so a small glass is harder to knock over. Thin-based ones chip almost immediately.
What spirits suit sipping from a shot glass?
Almost none. Anything worth sipping wants room above the liquid to gather aroma: a Glencairn, a copita or a small rocks glass. Keep the shot glass for chilled vodka, aquavit, blanco tequila and layered shooters that need the narrow bore.
