Most brands come to us with a look in mind: a reference image, a competitor's bottle they admire, sometimes a rough sketch.
What's usually still open is the commercial side: how many units you need, where the product sells, and what it has to land at per unit. Those three decisions influence almost every part of the finished specification.
A Life has more than 20 years of experience manufacturing kitchenware and tableware for brands across international markets, and the same questions come up at the start of nearly every oil and vinegar bottle project. Let’s take a look through them together below.
If it's the specifications you're after (glass grades, spout options, certifications, and variants), those live on our oil and vinegar bottle page.
Quick Summary1. Who decides the glass grade, my brand or the manufacturer? Both. You bring the target price, volume, and market position. The manufacturer confirms what's achievable within that, and it's often a conversation rather than a single answer handed over. 2. What size should my bottle be? It depends on where the bottle sells and how it’s used. Hospitality bottles generally run larger to reduce refilling, while retail and cruet sizes tend to be guided by shelf space, price point and table footprint. 3. Does my target landed price need to include packaging and branding, or just the bottle itself? Landed price generally refers to the total cost of the finished product once it reaches your market, so branding and packaging sit inside it alongside shipping and import costs. It's worth being generous here, because a figure based on the bottle alone tends to look very different once branding and packaging go in. 4. Do I need a 3D file before I get in touch? A 3D file is the preferred starting point, since it gives us the clearest view of the shape you have in mind. If you don’t have one yet, a sketch can still work, ideally a 2D drawing. |
Start with Where the Product Will Sell
Where a bottle sells changes what it actually needs to do, so it's worth settling the channel before you settle the look. Two bottles can share a silhouette and still be different products underneath.
Retail ranges
For a retail range, the bottle needs to work within the available shelf space and packaging format. Its height and base diameter can affect the carton dimensions, the number of bottles packed into each carton and the cost of transporting them. These factors are best considered while the bottle shape is still being developed.
Hospitality and food service
Bottles used in hospitality and food service are likely to be handled and refilled more frequently than retail products. The design should account for grip, pour control and repeated use, particularly around the neck, spout and branded areas. If the bottle needs to withstand commercial dishwasher use, include this requirement in the brief so the materials and branding method can be assessed accordingly.
Gifting and cruet sets
For gifting and cruet sets, the finish and packaging contribute to how buyers perceive the product before opening it. A matched oil and vinegar pair should also be developed to consistent specifications, including the glass appearance, bottle proportions, branding placement and pourer finish.
Direct-to-consumer
Direct-to-consumer launches often begin with a smaller forecast volume, which can limit the available glass grades and production methods. Confirming the expected order quantity early helps the manufacturer recommend options that suit the scale of the launch. More on that below.
Establishing the sales channel early gives the manufacturer a clearer basis for recommending the bottle capacity, materials, packaging format and production approach.
How Big Should the Bottle Be?
Size follows the channel more than the product. The capacity of a retail bottle needs to suit its shelf positioning and intended price point. Hospitality refills tend to run larger, since the priority is fewer trips back to the store cupboard. Cruet sets usually sit at the smaller end, where table footprint matters more than capacity. The right size for your range comes down to your market and how the product will be used.
More importantly, size feeds straight back into cost. A larger bottle uses more glass and adds freight weight, and it can also change how the bottles are packed and shipped. If your landed price is fixed, this is one of the first things worth revisiting.
How Volume Decides Your Glass
Minimum order quantity, the smallest run a factory will produce, catches out more first-time briefs than anything else. Borosilicate starts at 1,000 units, while soda-lime starts at 50,000. The gap isn't arbitrary either; soda-lime runs on high-volume automated lines that aren't worth setting up for a short order.
The Best Sustainable Materials for Kitchenware (And When to Use Each)
Different materials suit various product categories, and each comes with real trade-offs to consider before you settle on your product’s final specifications.
| Glass grade | Starting MOQ | Best suited to | Worth knowing |
| Borosilicate | 1,000 units | Premium, lower-volume lines | Thermally resistant and durable, so it holds up well at a smaller run |
| Soda-lime | 50,000 units | Wider retail ranges at scale | More cost-effective per unit, but only viable once volume is genuinely there |
For an initial run of a few thousand units, borosilicate is usually the viable option. Soda-lime only becomes practical when the forecast volume can support its 50,000-unit MOQ. Confirming volume early avoids developing a specification that cannot be quoted at the required scale.

Stock Shape or Custom Mould?
After the minimum order quantity, tooling is often the biggest cost decision in a bottle project, and you usually have two options: stock shape or custom mould.
A stock shape uses a mould that already exists. Tooling requirements are usually lighter, so upfront costs tend to be lower and development can move faster while you brand and finish an established form. The trade-off is that the silhouette isn’t exclusive to you.
A custom mould gives you a shape nobody else has. It involves a tooling investment and additional development time before sampling can begin, with both depending on the complexity of the design. That cost is spread across the production run, so custom tooling tends to make more sense as volume increases.
Most brands start on a stock shape and move to custom tooling once a range proves itself. There's no penalty in that order, and it's usually the cheaper way to find out what your market responds to.
Getting the Pour Right
Pour is the detail buyers most often overlook and the one they raise most after launch. It’s governed by the neck and the hardware, and both need settling while the shape is still open.
Neck geometry
The shape and width of the neck govern flow rate and control. Too wide, and pouring feels sloppy. Too narrow, and it slows down a product that’s meant to feel effortless on the table.
Oil versus vinegar behaviour
Oil is viscous and pours slower. Vinegar is thin and prone to dribbling. That difference matters most in a matched cruet set, where both bottles need to feel consistent as a pair even though the liquids inside them behave nothing alike.
Pourer trade-offs
Stainless steel collars and pourers suit a modern, premium aesthetic and resist corrosion over time. Silicone-sealed options give a reliable, drip-resistant pour and flex across different bottle neck sizes. Neither is universally better. The choice comes down to the finish you're chasing and how the product will actually be used.
This is where engineering input earns its keep. A bottle that samples beautifully and drips on every second pour isn’t a finished product yet, no matter how good it looks sitting still.
When to Decide Branding and Packaging
The branding method depends on the glass and the shape, so the three tend to be decided together.
Etching, sandblasting, laser engraving and screen printing each suit different finishes and budgets. What reads cleanly on matte, sandblasted glass can disappear on a polished surface, and a tightly curved panel limits how large a print area you have to work with. It's worth knowing which method you want before the shape is fixed, since the two can pull in different directions.
Packaging comes into it earlier than most people expect, particularly for retail, since it locks in dimensions and pack configuration before production begins.
Recyclable and reusable formats hold up well when they're specified properly: FSC-certified cartons, moulded pulp inserts, refill-ready formats. Our kitchenware page covers the options across the wider range.
How Long Does It Usually Take?
Most projects move through the same broad stages: sampling first, then production once a sample is signed off, then freight to your market. A custom mould adds a tooling stage before sampling can start, which is worth factoring in if your launch date is tight.
How long each stage takes depends on the design, order size and destination market. Time of year plays a part as well, since factory shutdowns around major holidays can push out the weeks either side of them. A realistic timeline is best confirmed once your specification and volumes are clear.
If you’re working to a fixed on-shelf date, it’s the single most useful thing to include in a first enquiry. It often settles the tooling question on its own.
Building a Matched Range
Brands rarely want just one product. Oil and vinegar bottles sit naturally alongside salt and pepper mills, glass jars, and the wider tableware category.
Developing them together with one partner keeps proportions, glass tone, and branding placement consistent across the range. Sourcing from several suppliers often leaves small inconsistencies behind: a slightly different glass tone here, a logo sitting just a touch off there. None of it is glaring on its own, but it adds up once the whole range sits together on a shelf.
What to Have Ready Before You Enquire
Answer as many of these as you can and your first quote will come back quicker and closer to the mark.
- Material preference, or openness to guidance
- Rough size, in millilitres
- Market and sales channel
- Estimated volume
- Target landed price
- Branding method
- Packaging requirements
- Any fixed on-shelf date
- A 3D file, or a sketch (ideally a 2D drawing) if you don’t have one
If a 3D file isn’t ready yet, that doesn’t need to hold anything up. A sketch still gives us a starting point, ideally a 2D drawing, and reference images or a product you’re trying to move away from are useful to send alongside it.
Ready to Brief Your Bottle Project?
If you’ve worked through the decisions above, you’re in a strong position to brief a manufacturer properly. If you haven’t, that’s fine too. Send us your brief with a 3D file, or a sketch (ideally a 2D drawing) if you don’t have one yet, and we’ll give you no-obligation feedback on materials, structure and production feasibility.
