# Mini Liquor Bottles: 50 ml Sizes, Shapes and Bulk Buying

> Mini liquor bottles explained: how big a 50 ml bottle is, glass vs plastic minis, caps, travel rules, and how brands buy empty mini alcohol bottles in bulk.

Published 2026-10-21 · Updated 2026-10-21 · Shanghai Mars Glass Co., Ltd.

Mini liquor bottles are small spirits bottles, almost always 50 ml (1.7 US fl oz) in the US, which is a little more than one 1.5 oz shot. They are also called nips, shooters or airplane bottles, and they come in glass for premium and gift use or in PET plastic for high-volume, low-cost lines. Brands buy empty minis in bulk from glass bottle suppliers, typically in quantities of 10,000 pieces or more, with caps matched to the neck finish.

## What size are mini liquor bottles?

The standard mini is the 50ml bottle. It is the smallest size on the traditional US list of authorized spirits sizes, and it is what most retailers mean by a mini or by nip bottles. Other small liquor bottles you will see:

| Size | US fl oz | Common names | Typical use |
|---|---|---|---|
| 30 ml | 1.0 | Tasting mini | Sample kits (check market rules) |
| 50 ml | 1.7 | Mini, nip, shooter, airplane bottle | Retail singles, minibars, gifts |
| 100 ml | 3.4 | Small flask, travel size | Gift sets, travel retail |
| 187 ml | 6.3 | Split (wine) | Single-serve wine and sparkling |
| 200 ml | 6.8 | Half pint | Convenience and pocket flasks |

A 50 ml mini typically stands 90 to 120 mm (3.5 to 4.7 in) tall with a body diameter of about 30 to 40 mm (1.2 to 1.6 in). It holds roughly one US shot, so the term "mini shot bottles" is accurate. For every size from 50 ml up to the 1.75 L handle, see our [liquor bottle sizes guide](/guides/liquor-bottle-sizes-guide/).

Mini rosé and other single-serve wines usually come in 187 ml splits rather than 50 ml minis. Our wine bottle sizes guide covers those formats.

## Why do brands make mini alcohol bottles?

Minis cost more per milliliter than a full bottle, but they earn their place in a range for several reasons:

- **Sampling.** A 50 ml lets a new customer try a product at low risk, at tastings, trade shows or in-store promotions.
- **Gift and discovery sets.** Three to six minis in a box or tube make a tasting flight or advent calendar.
- **Minibars and travel.** Hotels and airlines use minis because each one is a single serving.
- **Events and favors.** Weddings and corporate events order personalized minis.
- **Price-point entry.** A low shelf price puts the brand in front of buyers who would not pay for a 750 ml.

For a distiller, the key point is consistency: a mini should look like a scaled version of the main bottle, or at least share its colors and decoration, so it builds recognition rather than looking like a separate product.

## Glass or plastic: which mini bottles should you choose?

| Factor | Glass minis | PET plastic minis |
|---|---|---|
| Look and feel | Heavy, clear, premium | Light, can look disposable |
| Breakage | Can break if dropped | Practically unbreakable |
| Weight in shipping | Higher | Much lower |
| Product contact | Inert; no flavor transfer | Suitable for spirits, but check grade and shelf life |
| Decoration | Screen printing, frosting, decals, spray coating | Mainly labels and shrink sleeves |
| Recycling | Widely recyclable | Recyclable, but small items are often missed in sorting |
| Best for | Premium spirits, gift sets, samples | High-volume nips, venues where glass is banned |

If your brand is positioned as craft or premium, glass minis usually match the main bottle better. If you sell very large volumes of low-price nips, PET is often chosen on cost and weight. Some US states and towns have debated or introduced deposits or other rules for nips, so check local regulations for the markets you sell in.

## What shapes do mini liquor bottles come in?

Stock glass miniatures come in a few classic shapes, and almost any full-size design can be made as a mini with a custom mold.

- **Oslo (round shoulder):** the most common stock mini. A round body, sloping shoulder and short neck. Our [50 ml mini Oslo extra flint bottle](/products/spirits-bottles/mini-oslo-extra-flint-glass-bottle-50ml-ropp/) is a typical example, available clear or frosted with an ROPP cap.
- **Flask:** flat front and back, easy to label, good for gift boxes. See the [flat glass bottle in 50, 200 and 250 ml](/products/olive-oil-bottles/flat-glass-bottle-spirits-olive-oil-50-250ml/).
- **Round with cork:** a small version of a cork-finish spirits bottle. Our round glass liquor bottle with cork comes in 50 ml as part of a range up to 1,000 ml.
- **Mini replicas:** a scaled copy of your 700 or 750 ml bottle. This needs its own mold set.

Mini tequila bottles, mini whiskey bottles, miniature rum bottles and small vodka bottles are not separate formats. They use the same 50 ml sizes, with the shape and decoration taken from the category style. Our [tequila bottles guide](/guides/tequila-bottles-guide/) and whiskey bottles guide describe the typical looks for each category.

## Which caps fit mini liquor bottles?

Minis use small neck finishes, so check the closure before you approve the bottle.

- **Aluminum screw caps** in small diameters such as 18 mm are the most common choice. They are inexpensive and easy to apply by hand or machine. See our [aluminum screw caps for mini liquor bottles, 18–28 mm](/products/closures/aluminum-screw-cap-mini-liquor-bottle-18-28mm/).
- **ROPP caps** give a tamper-evident band, but need a roll-on capping head sized for the cap.
- **Small corks** suit mini replicas of cork-finish bottles, though they cost more and are slower to apply.

Ask for the neck finish drawing and test caps on real samples, especially if the bottle and cap come from different suppliers. Glass shot bottles with screw caps are only as leak-proof as the cap, liner and neck combination.

## Can you bring mini bottles of alcohol on a plane?

For travelers in the US, the TSA carry-on rule allows liquids in containers of 3.4 oz (100 ml) or less, packed in one quart-size bag. A 50 ml mini fits within that limit. In checked bags, the TSA generally allows alcoholic drinks up to 70% ABV in unopened retail packaging, with a quantity limit per passenger for drinks between 24% and 70% ABV.

Federal aviation rules, however, do not allow passengers to drink alcohol they bring on board; only drinks served by the airline may be consumed. Rules can change and differ by country, so check current TSA, airline and destination rules before you fly. For brands, this is why airline and travel-retail buyers stock minis: they fit the size limits and serve one drink.

## How do you buy mini liquor bottles in bulk?

Consumers searching for where to buy mini alcohol bottles usually want filled bottles from a licensed liquor store. Businesses need empty mini liquor bottles to fill themselves. Filling spirits for sale requires the appropriate licenses, so bulk empties are sold to distilleries, bottlers and brand owners.

When you order mini liquor bottles in bulk, plan for:

1. **MOQ.** Stock glass minis typically start in the thousands to tens of thousands of pieces. Our 50 ml Oslo bottle has an MOQ of 10,000 pieces with a reference price of $0.10–0.15 per piece FOB. See [glass bottle MOQs and lead times](/guides/glass-bottle-moq-and-lead-times/) for how custom runs differ.
2. **Filling accuracy.** A small error matters more on a small bottle. Confirm the brimful capacity and the fill height so your filler hits the declared 50 ml.
3. **Handling.** Small, light bottles can tip on conveyors. Check your line's change parts and guides before ordering.
4. **Packing.** Minis ship in large quantities per carton. Ask how they are divided and protected inside the carton.
5. **Caps and decoration together.** Order caps in the same shipment, and decide on printing or frosting at the same time so the first batch matches the full-size bottle.

## What about mini glass jars with lids?

Some buyers searching for miniature glass bottles actually need tiny jars for spices, jam samples, candles or favors. Mini glass jars with lids in 30 to 120 ml are a different product with a wide mouth and a screw or two-piece lid. Our [small wide-mouth mason jars, 30–120 ml](/products/glass-jars/small-wide-mouth-glass-mason-jar-30-120ml/) are an example. Our mason jar sizes guide covers the wider jar range.

## FAQ

**How big is a 50 ml bottle?**

**What are mini liquor bottles called?**

Mini liquor bottles are called miniatures, minis, nips, shooters, airplane bottles or airline bottles. In the US the standard mini size is 50 ml. Some markets also use 30 ml and 100 ml miniatures.

In the US, 50 ml minis fit within the TSA carry-on liquids allowance of 3.4 oz (100 ml) per container, packed in your quart-size liquids bag. However, FAA rules do not allow passengers to drink their own alcohol on board; only drinks served by the airline may be consumed. Check current TSA and airline rules before you travel.
