A small notch near the base of a whiskey bottle can be an orientation feature. Compatible labeling equipment uses it as a reference to rotate the bottle so the label lands in a specified position, such as below an embossed logo. Not every indent is an orientation feature, and not every bottling line reads the same kind of notch. Confirm the feature on the bottle drawing and with the bottler before adding it to a mold.
When does a spirits bottle need orientation?
Orientation matters when the label must line up with a feature already on the bottle. Common examples are a front label centered under a raised brand mark, a back label placed relative to existing print, or a label positioned to avoid a visible seam. If a plain round bottle has no feature the label needs to align with, a dedicated notch may not be necessary. The bottler still needs to approve label placement and how the bottle runs on the line.
Orientation and label fit are separate checks. A label can sit flat but land off-center relative to the logo. It can also land exactly where intended and still wrinkle because its shape does not match the glass.
Can the bottler use something other than a notch?
| Reference | What to confirm before choosing it |
|---|---|
| Base or side notch | The specific machine can read the feature at the proposed location. Request the equipment team’s geometry and tolerance requirements before finalizing the bottle drawing. |
| Embossing, debossing or glass seam | The installed vision or sensor setup can distinguish the chosen feature on the actual glass and finish, and use it to place the label consistently. |
| Existing print, label or capsule | The reference is already present at the orientation station and is applied consistently enough to locate the next label. |
These options depend on the installed machine and configuration. The ENOS ZETA equipment specification lists options based on notches and other package features. Cavagnino & Gatti’s equipment documentation describes vision systems that use glass seams and molded features. Neither reference establishes compatibility with a particular contract bottler’s line.
What belongs on the drawing before mold approval?
Mark the front face, the artwork centerline, the desired label position and the feature the machine should read. Ask the bottler to define the location and tolerances it needs relative to that feature. For a notch, the glass supplier should review manufacturability and confirm how it will be represented on the drawing. Do not copy the dimensions of a notch from a different bottle.
Check with the bottler before ordering a custom mold, not after the decorated sample is ready. The custom mold development guide explains where these decisions fit into drawing review and first sampling.
How do you approve label alignment on actual bottles?
- Give the bottler representative bottles with the intended glass finish, the current bottle drawing and production-representative labels.
- Agree what counts as acceptable alignment. Define the permitted shift or rotation relative to the intended feature and how it will be measured.
- Trial the samples on the intended equipment. Ask the bottler to check repeatability, including bottles entering in different orientations where that matches normal line operation. Record the sample IDs, label revision, equipment setup and observed results.
A hand-positioned mockup can approve the look, but it does not prove the machine will find the reference reliably. If you are planning a pilot run, use the first spirits bottling run guide for the rest of the buying checklist.
What should you send with a bottle inquiry?
Send RS Glass & Jingbo Glass the bottle model or proposed shape, artwork showing where the label should sit, the machine team’s orientation requirements and your first-run quantity. If you’re comparing stock designs, start with the 700 ml spirits bottle catalogue and request the drawing for the exact model. Catalogue photos do not establish whether a machine-readable reference is available.
Research note
The question came from two r/whiskey discussions about a notch near the bottle base and an indent on a bottle. The discussions informed the topic; they do not identify the function of every photographed mark or establish compatibility with any bottling line.
