Every restaurant that serves carbonated drinks — soda, sparkling water, draft beer — eventually faces the same decision: stick with CO2 cylinders, or switch to a bulk supply system. It seems like a small operational detail, but getting it wrong can mean overpaying for months, running out of gas mid-service, or paying for storage infrastructure you didn’t actually need.
Here’s how to figure out which option actually fits your restaurant’s size, volume, and layout.
The Core Difference
Cylinder CO2 is delivered in individual pressurized tanks — typically 6kg, 10kg, or larger — that get swapped out and refilled (or exchanged) as they empty. It’s the standard setup for most independent restaurants and bars.
Bulk CO2 is delivered via a fixed on-site tank, refilled directly by a tanker on a scheduled basis. It’s more common in high-volume venues, breweries, and multi-outlet operations where gas consumption is too high for cylinders to be practical.
The right choice comes down to how much CO2 you actually use, how much space you have, and how predictable your consumption is.
When Cylinder CO2 Makes More Sense
Cylinders are usually the better fit if your restaurant is:
- Independent or single-location, with moderate carbonation needs (a soda gun, a few draft lines)
- Space-constrained, without a dedicated area for a bulk tank installation
- Newer or still establishing consumption patterns — cylinders let you scale order frequency up or down without being locked into a tank size
- Not consuming CO2 fast enough to justify tank installation costs
The main advantage of cylinders is flexibility. There’s no upfront infrastructure investment, and you only order what you need, when you need it. The tradeoff is that per-kilogram cost is generally higher than bulk, and you’re dependent on timely deliveries — running out mid-Friday-night service is a real risk if your reorder timing slips.
When Bulk CO2 Makes More Sense
Bulk supply tends to be the better economic choice once a restaurant hits a certain consumption threshold — typically multi-outlet groups, high-volume bars, breweries, or venues with several draft lines running continuously. Signs it might be time to consider bulk include:
- You’re reordering cylinders multiple times a week, or storing more cylinders than feels manageable
- You have consistent, high-volume usage rather than seasonal or unpredictable demand
- You have the physical space (usually outdoor or a dedicated utility area) for a fixed tank installation
- You want to reduce per-unit cost — bulk CO2 is generally cheaper per kilogram than cylinder gas once volume justifies it
The tradeoff is the upfront commitment: tank installation, a supply agreement with scheduled refills, and less flexibility if your consumption drops significantly. Bulk works best when demand is steady and predictable, not when it fluctuates seasonally.
Comparing the Two: What Actually Matters
Cost per kilogram: Bulk is typically cheaper at scale, but only pays off once consumption is high enough to offset installation and commitment costs. For lower-volume restaurants, cylinders often work out more cost-effective overall.
Storage space: Cylinders need a secure, ventilated storage area but no permanent installation. Bulk tanks require dedicated space, usually outdoors, and installation coordination with your supplier.
Delivery frequency: Cylinder restaurants typically order weekly or biweekly depending on usage. Bulk tanks are refilled on a scheduled cycle set by consumption rate, reducing the number of deliveries and the risk of running out unexpectedly.
Flexibility: Cylinders win here — you can adjust order volume easily as your business changes. Bulk requires more forward planning and is harder to scale down quickly.
Risk of running out: Cylinders carry more risk if reorder timing isn’t managed carefully. Bulk tanks with monitored refill schedules significantly reduce this risk for high-volume venues.
A Simple Way to Decide
If you’re not sure which category your restaurant falls into, look at your reorder pattern over the last two to three months. If you’re consistently ordering cylinders more than once a week and have space for a tank, it’s worth getting a bulk supply quote to compare actual cost savings. If your usage is moderate, seasonal, or you don’t have space for a fixed installation, cylinders remain the more practical option — and there’s no rule that says you can’t switch later as your volume grows.
How Infiinite Distribution Supports Both
We supply restaurants, bars, and breweries across Europe with both cylinder and bulk CO2, and we help new clients figure out which setup actually fits their consumption pattern rather than defaulting to whichever is easier for us to deliver. If you’re unsure whether bulk makes sense yet, we can review your current cylinder usage and give you a straight answer — including a cost comparison — before you commit to any tank installation.

Frequently Asked Questions
Is bulk CO2 always cheaper than cylinder CO2?
Per kilogram, yes — but only once your consumption volume is high enough to offset the installation and commitment costs of a bulk tank. For lower-volume restaurants, cylinders are often more cost-effective overall.
How do I know if my restaurant uses enough CO2 for bulk supply to make sense?
A general signal is reordering cylinders more than once a week consistently, combined with having the physical space for a fixed tank installation.
Can I switch from cylinders to bulk CO2 later as my restaurant grows?
Yes — most suppliers can transition a client from cylinder to bulk supply once consumption and space justify it. There’s no need to commit to bulk from day one.
What space do I need for a bulk CO2 tank?
Bulk tanks typically require a dedicated outdoor or utility area with tanker access for scheduled refills. Space requirements vary by tank size, so it’s worth getting a site assessment from your supplier.
Does switching to bulk CO2 reduce the risk of running out during service? Generally yes, since bulk tanks are refilled on a monitored, scheduled cycle, reducing dependence on manually timed cylinder reorders.
