50ml mini bottles are the standard sampling format for spirits brands: big enough for a proper tasting pour, small enough to fit in gift sets, minibars and trade-show bags. Sourcing them is not the same as scaling down your 750ml order, though. Neck finish, glass weight, filling-line handling and MOQ all behave differently at this size, and this guide covers what to check before you order.
Why spirits brands order 50ml mini bottles
For a craft distillery or a new spirits label, minis are a marketing tool first and a packaging line second. The same 50ml format covers several distinct jobs:
- Trade sampling: sending distributors, buyers and bartenders a sealed, labeled bottle instead of a decanted vial.
- Consumer trial: a low-price entry point at the checkout counter that lets shoppers try a gin or whiskey before committing to a full bottle.
- Gift sets and advent calendars: tasting flights of three to twenty-four minis are a strong seasonal format for premium brands.
- Hospitality: hotel minibars, airlines and events, where portion control and breakage resistance matter.
Because each mini is often the first bottle a customer holds, it should look like your brand, not a generic vial. That is the main reason brands upgrade from basic stock minis to decorated or custom-shaped spirits sample bottles. For the full spectrum of retail formats, see our liquor bottle sizes guide; this article focuses on sourcing the small end.
Mini and small spirits formats compared
Most brands do not stop at 50ml. A mini is often paired with a 100ml to 200ml “half-pint” format for gifting or travel retail. The table below lists small liquor formats from the GlassRock catalog, with the specifications published on each product page.
| Bottle | 定員 | Glass weight | Height | Neck size | Qty per pallet |
|---|---|---|---|---|---|
| オスロ ミニ | 50 ml | 76 g | 94 mm | 17.8 mm (crown diameter) | 17,250 |
| ミニフラスコ | 100 ml | 200 g | 105 mm | 23.5 mm (crown diameter) | 5,120 |
| フラットフラスコ | 150 ml | 280 g | 120 mm | 23.5 mm (crown diameter) | 9,520 |
| オスロ 200 | 200 ml | 300 g | 156 mm | 28.5 mm (bore diameter) | 3,990 |
| ソラリス 375 | 375 ml | 420 g | 179 mm | 18.5 mm (bore diameter) | 2,340 |
The オスロ ミニ is a 50ml extra flint bottle: the high clarity shows off the color of an aged rum or a botanical gin, which matters when the liquid itself is what you are selling. Its sibling sizes (200ml, 500ml, 700ml) let you build a consistent family from sample to full bottle.
What to specify for spirits sample bottles
Neck finish and closure
Minis have their own neck finishes, so the closure on your 750ml bottle will not fit. Ask for the technical drawing, confirm the finish dimensions with your closure supplier, and check that your capping head can run that size. Our neck finish compatibility guide explains what to compare. Tamper evidence matters more on minis, which are often handed out loose.
Glass weight and freight
As the chart above shows, a 50ml bottle can carry close to twice as much glass per milliliter of spirit as a lightweight 700ml bottle. That is physics, not inefficiency: the walls and base cannot scale down in proportion to volume. Budget freight and packaging per liter of product, not per bottle, when you compare formats.
Filling and labeling
- Stability: short, light bottles tip easily on conveyors. Check whether your filler needs change parts or pucks for the mini’s diameter and height.
- Label panel: a 94mm-tall bottle leaves little room for mandatory text. Plan alcohol content, volume and origin statements before artwork, not after.
- Decoration: direct screen printing is popular on minis because it frees the small label panel. See our decoration techniques guide for options.
If your brand leans toward a pocket or travel format, the ミニフラスコ (100ml) gives a flat profile that packs efficiently into gift boxes.
Stock vs custom minis: MOQ and volumes
The main decision is whether a stock mini with decoration is enough, or whether you need a private mold that mirrors your full-size bottle’s silhouette.
| Criterion | Stock mini | Custom mini |
|---|---|---|
| Minimum order | 1 × 20-foot container of mixed references | Around 12,000 units on average |
| Brand differentiation | Via labels, screen printing, closures | Unique shape, embossing, miniature of your main bottle |
| Tooling | None | Mold required (see our MOQ guide) |
| Best for | Launches, trade samples, seasonal sets | Established brands with recurring mini volume |
The mixed-container rule is useful for minis: because a 50ml bottle is so compact (the Oslo Mini ships 17,250 units per pallet), you can combine a modest mini quantity with your full-size bottles in the same shipment rather than tying up a whole container on samples.
Between the 100ml and 200ml formats, the 150ml フラットフラスコ is an option for hip-flask style gifting.
Nip bottles wholesale: pre-order checklist
- Confirm that 50ml is a permitted fill size in each target market (it is a US TTB standard of fill; check other markets with your regulatory advisor).
- Request the technical drawing and datasheet, then validate the neck finish with your closure supplier.
- Run filling and capping trials on samples before committing to volume.
- Lock the label or print layout around the small panel, including mandatory statements.
- Plan the outer packaging: dividers or trays for gift sets, and shippers for retail.
- Decide stock vs custom based on 12-month mini volume, not launch volume alone.
- Check local rules: some US municipalities have restricted nip sales, which can affect where minis can be sold.
よくあるご質問
What are 50ml mini bottles called?
In the spirits trade, 50ml mini bottles are also called miniatures, nips or airline bottles. 50ml is roughly 1.7 US fluid ounces, slightly more than a standard 1.5 oz shot.
Is 50ml a legal size for spirits in the US?
Yes. 50ml is one of the authorized standards of fill for distilled spirits under US TTB rules, which is why it is the dominant miniature size for American retail, hotel minibars and airlines.
What is the MOQ for 50ml mini bottles?
At GlassRock, in-stock bottles such as the Oslo Mini can be ordered from one 20-foot container of mixed references, while customized liquor bottles start at around 12,000 units on average, depending on the design.
Can I use the same closure on my mini as on my 750ml bottle?
Usually not. Minis have much smaller neck finishes than full-size spirits bottles, so caps, corks and capping heads must be matched to the mini’s own finish drawing.
Why do mini bottles cost more per liter to ship?
A mini carries more glass per milliliter of spirit than a full-size bottle, so for the same volume of product you ship more glass weight, more units and more packaging.
