A moonshine jug for a craft distillery is normally bought as a family of 375 ml, 750 ml and 1 L bottles, all three of which are TTB-authorized standards of fill. The flagship 750 ml stock jug stands 248 mm tall, measures 98 mm across the body, weighs about 620 g in flint glass and takes either an 18.5 mm bar-top cork or a 28 mm screw cap. The neck finish has to be fixed before anything else, because a cork bore and a threaded finish cannot share one neck.
Stock jug sizes and specifications
Each size does a different commercial job. The 375 ml suits tasting-room flights, gift sets and shelf tests in control states. The 750 ml is the retail flagship, and the 1 L serves bar call, duty-free and club-store formats. Brands that want a sampler add a 50 ml or 100 ml miniature, which we source through the miniature liquor bottle range in matching jug proportions.
| Capacity | Height (mm) | Body diameter (mm) | Neck finish | Weight (g) | Closures | Units per 40HQ |
|---|---|---|---|---|---|---|
| 50 ml miniature | 92 | 44 | 18 mm screw | 85 | ROPP, aluminum screw | ~210,000 |
| 375 ml | 205 | 82 | 18.5 mm bar-top / 28 mm screw | 420 | Cork, synthetic T-cork, ROPP | ~41,000 |
| 750 ml | 248 | 98 | 18.5 mm bar-top / 28 mm screw | 620 | Cork, synthetic T-cork, ROPP | ~26,000 |
| 1 L | 275 | 108 | 21.5 mm bar-top / 33 mm screw | 780 | Cork, synthetic T-cork, ROPP | ~19,000 |
Brimful capacity on the 750 ml jug usually falls between 765 and 775 ml. That leaves the filler the 2% headspace needed for thermal expansion and for TTB net-contents compliance. Capacities outside the stock family, from 200 ml to 1.75 L, need a dedicated mold.
A size ladder only works as a brand system when the 375 ml looks like a scaled-down 750 ml. The angle of the finger loop, the shoulder break and the label panel geometry should match across all capacities, so the molds have to be drawn as a family at the start instead of being scaled later.
Proportions that make a jug read as moonshine
The form is tightly constrained. A classic 750 ml jug is roughly 240 to 260 mm tall and 95 to 105 mm across the body, with a shoulder that breaks sharply where a wine bottle would slope. The neck is narrow, at 18.5 mm to 21.5 mm inner diameter.
When we check a jug drawing, these are the dimensions we look at first:
- Belly. A ratio of body diameter to height near 0.40, with the widest point at about 55% of the bottle height. A more spherical belly looks like a cider growler; a flatter one looks like a maple syrup bottle.
- Neck. Short, 35 to 50 mm from shoulder to finish. A long neck loses the jug character at once.
- Finger loop. A molded lug of glass arcing from shoulder to neck, formed in the press-and-blow or blow-and-blow process. It adds 15 to 25 g of glass and needs either a side action in the mold or a carefully angled parting line, which is why a true jug is more demanding to make than a plain round bottle.
- Walls. Held between 2.8 mm and 3.5 mm on the 620 g version, enough for the filling line and for rough handling by the consumer.
- Punt. Shallow, typically 8 to 12 mm. Jugs are stored upright and have no need for a sediment trap.
- Base. A stippled or knurled ring 3 mm wide gives grip on a wet bar top and hides the scuffing that round-bellied bottles collect in transit.
Consumers never notice these details. A co-packer running a rotary filler at 80 bottles per minute does.
Weight is part of the message as well. Flint glass with a heavy base at 620 to 780 g feels like a serious spirit, while a 380 g lightweight jug comes across as a souvenir. The shape itself signals handmade and rural before anyone reads the label, so the liquid has to be consistent with that promise, including when it is a neutral grain spirit with flavoring.
Bar-top cork or screw cap
The traditional closure is a bar-top cork: a natural or synthetic cork on a wooden or plastic stem, sized for an 18.5 mm or 21.5 mm bore. Bar-top versions of the jug have a ground-finish bore to hold that fit. A screw cap needs a molded thread finish instead, 28 mm on the smaller jugs and 33 mm on the 1 L.
For a range that mixes corked and screw-capped SKUs, we advise keeping to one neck bore family so that a single capper head can run the whole line.
Child-resistant closures are generally not mandated for distilled spirits in the US. Two situations are worth watching. Low-ABV flavored moonshine sold through grocery channels can fall under state rules that treat it like a ready-to-drink product, and several European markets ask for child-resistant features on high-sugar liqueurs. A 28 mm CR-capable finish is available on the 750 ml jug as a mold option. Because it alters the neck drawing, it has to be specified before the mold is cut.
Embossing, printing and frosting
Surface texture does most of the work on this bottle. A smooth flint jug with a paper label looks like private label. Add a deep-relief corn motif, a county name or "DISTILLED & BOTTLED BY" lettering around the shoulder and the same jug looks like heritage.
Embossing is cut into the mold at a relief depth of 0.4 to 1.2 mm, and every bottle from that cavity then carries it with no further decoration step. The limit is ownership: a cavity cut with your name can only serve your brand. Distilleries not ready for that can use the stock jug, which has a flat label panel of roughly 90 × 110 mm on the 750 ml and optional generic "XXX" or corn-shuck motifs in shared molds.
After the mold, a typical build combines two or more of these:
- Ceramic screen printing in one to four inks. It withstands pasteurization and dishwashing much better than organic sprays, which matters because many flavored moonshines are hot-filled at 60 to 70 °C.
- Frosting, for example an acid-etch finish on a winter edition.
- Decals and paper seals applied by hand in the style of a tax strip, or a printed shrink band that imitates one.
Ink adhesion specifications and thermal-cycle testing are covered on our page for glass bottles for spirits. Jugs can be decorated on the same lines as the whiskey bottle range, so a distillery with a bourbon SKU and a shine SKU can share decoration setups between them.
Seasonal releases, such as a frosted winter bottle or an amber-tinted harvest edition, refresh the shelf while the shape stays constant. That is the reason to insist on flat, decoration-friendly panels and one consistent neck finish across the family. Some brands carry the same emboss motifs and closure color onto swing-top glass growlers for tasting-room refills and cocktails-to-go, so the range reads as one system from a 50 ml sampler to a 2 L growler.
US compliance points to design into the bottle
Net contents. TTB standards of fill for distilled spirits include 375 ml, 750 ml and 1 L. Treasury Decision TTB-165 (2020) added 700 ml and 900 ml. Any other custom capacity should be checked against the current list in 27 CFR 5.203 before the mold is cut.
Tamper evidence. Federal rules do not prescribe a closure type, but most control states and large chains expect visible tamper evidence. The breakaway band on an ROPP cap, a shrink capsule or a tax-strip-style seal all satisfy that. Paper tax strips over the closure were once required by many states. Most have since moved to per-bottle reporting, though several control states and many export markets still want a strip-style or shrink-band seal.
Label area. The mandatory government warning and health statements need a legible flat surface. The stock jugs reserve a back panel at least 90 mm tall so the warning text does not wrap around the belly curve, where it would fail readability checks.
Shipping. Bottles sold direct to consumers across state lines have to survive ISTA 3A parcel testing. A 620 g jug with 3 mm walls in a molded-pulp shipper passes drop tests that a 400 g lightweight bottle fails. Building these points into the drawing is much easier than re-tooling after a shipment is rejected.
Case packs and container loading
The three sizes behave differently in the warehouse, so case counts should be settled early.
- 375 ml (about 420 g): 12 or 24 per case.
- 750 ml (620 g): 12 per 5-ply corrugated case, about 8.6 kg gross.
- 1 L (roughly 780 g): usually 6 per case, which keeps the case under the 15 kg manual-handling limit that most US warehouses enforce.
Palletized in a 40HQ container, that works out to approximately 26,000 of the 750 ml jugs or about 19,000 of the 1 L.
Stock, semi-custom or full custom mold
There are three routes, and the right one depends on how far along the brand is.
- Stock. An existing 375, 750 or 1 L jug finished with frosting, screen print or decals. No mold is cut, which suits a first launch or a seasonal SKU.
- Semi-custom. The stock body with your name or motif embossed through interchangeable insert plates in the mold.
- Full custom. A proprietary mold family cut to your drawings. It is usually justified by a high committed annual volume across the family, or by a shape that is the brand in itself: a squat 300 ml jug, a squared "mason jar" hybrid, an oversized loop.
If a custom jug is likely within two years, we suggest launching on the stock bottle with decoration that will carry over, meaning the same label shape and ink palette. The custom mold then arrives as an upgrade and not as a redesign. When we scope a project, we settle the story the shape has to tell first and move to mold drawings afterwards.
Frequently asked questions
What is the minimum order for moonshine jugs?
Minimums are quoted for each project. They depend on whether the jug is stock, semi-custom or a new mold, and on the production line it is assigned to.
Can one bottle take both a bar-top cork and a screw cap?
No. A bar-top cork seats in a smooth ground bore of 18.5 mm or 21.5 mm, and a screw cap needs molded threads on a 28 mm or 33 mm finish. Choose one per mold.
Can the jugs be hot-filled with flavored spirits?
Yes, if the specification allows for it. The jugs are annealed to withstand a thermal shock differential of 42 °C, which covers a standard hot fill at 60 to 70 °C followed by a controlled cooling tunnel. Above 65 °C we recommend the 620 g heavyweight 750 ml jug over any lightweight variant, and each new recipe should be validated with thermal-cycle testing before production.
How long does a custom mold take?
Timing is quoted per project once the mold design, the decoration and the line schedule are confirmed.
Do the bottles meet US packaging expectations?
The stock capacities match TTB standards of fill, and the jugs are drawn with the back panel that warning text needs. Samples, inspection scope and claims terms are agreed for each project before the order is placed.
Can a vintage look be built with modern decoration?
It is the brief we see most often for this bottle. A typical build starts from a stock jug body and adds acid-etch frosting, two-color ceramic screen printing, shoulder lettering embossed through insert plates, and a printed shrink band styled as an old tax strip.
