How to Choose the Right CO2 Cartridge Size for Your Beer Dispensing System
Choosing the wrong cartridge size can lead to pressure instability, frequent interruptions, or even customer dissatisfaction. This section helps you match the right CO2 cartridge to your equipment type, serving frequency, and operational needs — based on practical, field-tested logic.
The Three Key Factors That Determine the Right Size
1. Your Daily Beer Output
How many liters of beer are you dispensing per session or per day?
- < 5L/day → Use 8g cartridges
- 5–20L/day → Use 16g cartridges
- 20L/day → Use 74g cartridges
Each cartridge size delivers a different volume of usable CO2. For example:
| Cartridge Size | Approximate Beer Dispense Capacity* |
| 8g | 1.5–2.5 liters |
| 16g | 3–5 liters |
| 74g | 10–25 liters |
*Actual output may vary based on temperature, tubing length, head pressure, and keg type.
2. Equipment Type and Space Constraints
The physical structure of your draft system determines which size fits:
| Cartridge Size | Best-Fit Equipment |
| 8g | Portable growlers, picnic taps, single-use kegs |
| 16g | Desktop kegerators, compact bar towers, dual tap setups |
| 74g | Restaurant beer towers, mobile beer trucks, taproom systems |
If your system has a fixed cartridge slot, make sure you verify thread compatibility (e.g. 3/8″-24 UNF, 1/2″-20 UNF) and max pressure rating.
3. Service Environment and Refill Tolerance
Frequent CO2 cartridge changes = labor time + service interruption. Here’s how different sizes behave operationally:
| Scenario | Cartridge Recommendation |
| Outdoor beer booths (high foot traffic) | 74g — fewer swaps under pressure |
| Home or café service (intermittent pours) | 16g — efficient with moderate use |
| Pop-up events or tasting sessions | 8g — quick, low-cost, lightweight |
In high-volume settings, even 16g may feel insufficient. Upgrading to 74g or a refillable cylinder could save time and boost consistency.
Bonus Tip: Use Size + Thread as a Matching Pair
For example:
- A 16g CO2 with 3/8″-24 UNF thread fits many home keg kits.
- A 74g CO2 with 5/8″-18 UNF thread fits commercial regulators.
- Custom applications may require 1/2″-20 or M10x1 threading — we support all common beer system standards.
Summary: Which Size Should You Choose?
| Cartridge | Ideal Use Case | Key Advantage |
| 8g | Growlers, single-serve systems | Lightweight and fast-swap |
| 16g | Home kegs, café draft | Best balance of power and size |
| 74g | Commercial taps, beer trucks | Long-lasting, minimal changeover |

What Is Beer Gas? Choosing the Right Gas Blend for Your Draft System
Beer gas isn’t just CO2. It’s the art of balancing pressure, texture, and flavor stability in your draft beer system. Choosing the wrong gas mix can lead to over-carbonation, flat pours, or off-flavors. This guide helps you select the ideal gas blend based on beer type, system setup, and customer experience goals.
What Is Beer Gas?
Beer gas refers to any pressurized gas used to push beer through a draft system — typically a combination of:
- CO2 (Carbon Dioxide): Creates carbonation (bubbles) and pressure
- N2 (Nitrogen): Adds creaminess and smooth pour texture
- Sometimes Argon: For wine or hybrid systems (not typical in beer taps)
The right mix influences everything from foam thickness to pour speed to beer mouthfeel.
Common Beer Gas Blends and Their Applications
| Gas Mix Ratio | Gas Composition | Best For | Pour Texture | Notes |
| 100% CO2 | 100% CO2 | Lagers, IPAs, wheat beers, general use | Crisp, bubbly, standard foam | Most widely used, good for maintaining carbonation |
| 70/30 | 70% N2 / 30% CO2 | Stouts (e.g. Guinness), nitro ales | Creamy head, smooth flow | Requires restrictor faucet or stout tap |
| 60/40 | 60% N2 / 40% CO2 | Mixed-style beers, ales on nitro | Light creaminess, moderate carbonation | Versatile for modern craft systems |
| 75/25 | 75% N2 / 25% CO2 | Stronger stouts or dark ales | Dense foam, very low CO2 bite | Best used in high-pressure stout taps |
| Custom Mix | As requested | Specialty brews, regional preferences | Varies | OEM-customized gas blends available |
How to Choose the Right Beer Gas
Here’s a breakdown by beer style:
| Beer Type | Recommended Gas | Why |
| Lager, IPA, Pilsner | 100% CO2 | Keeps carbonation crisp, supports hop aroma |
| Nitro Stout (e.g. Guinness) | 70/30 N2/CO2 | Creamy head, smooth mouthfeel, less CO2 bite |
| Amber / Brown Ale | 60/40 N2/CO2 | Softer bubbles, enhances malt richness |
| 4.1g / 2g N2 | 75/25 N2/CO2 | Dense foam, traditional stout texture |
| Craft Experimental Brews | Custom | Tailor pressure, foam, and taste together |
Technical Considerations
- Pressure Settings: Mixed gases usually require higher PSI (~30–40 psi) compared to CO2 (~12–14 psi). Regulators must support mixed gas pressure.
- Tap Type: Nitrogen-heavy blends should be dispensed using restrictor faucets or stout taps to achieve the proper cascading pour.
- Line Length & Keg Storage: High CO2 pressure over time can over-carbonate beer if not balanced — proper gas mix helps control this.
Can Alizeemetal Supply Mixed Gas Cartridges?
✅ Yes. We support OEM pre-filling of:
- 70/30, 60/40, 75/25 beer gas blends
- Custom gas ratios for regional taste or draft specs
- Branded or unbranded cartridges with private label packaging
All gas is tested for:
- Food-grade purity
- Stable mix consistency
- Leak-proof performance at high pressure
💡 Ask about pre-filled mixed gas cartridges for your growler kits or stout tap systems.
What Factors Impact Beer CO2 Cartridge Quality?
A beer CO2 cartridge isn’t just a gas container — it’s a precision component in your draft system. Poor-quality cartridges can affect foam, flavor, safety, and even the equipment itself. Here’s what experienced beer equipment buyers check before choosing a supplier.
1. Internal Cleanliness = Foam Stability & Flavor Protection
Residue such as oil, metal particles, or moisture inside the cartridge can degrade CO2 quality — leading to off-taste, unstable foam, or beer haze. We use ISO-grade degreasing + high-temperature drying before filling to ensure internal surfaces are contaminant-free and beer-safe.
2. Food-Grade CO2 = Certified for Beer Use
Only 99.99% food-grade CO2 — tested by SGS and compliant with CE/TPED — should be used in beverage systems. Industrial-grade gas may cause metallic aftertaste or even violate food safety regulations in export markets.
3. Thread Precision & Leak Prevention = System Safety + Compatibility
CO2 cartridges for beer taps must deliver tight gas sealing while remaining smoothly compatible with growlers, kegerators, and portable draft systems.
We ensure:
- CNC-machined threading (1/2″, 3/8″, 5/8″) for dimensional accuracy
- 100% leak testing on every cartridge to ensure gas-tight integrity
- Batch-level inspection to avoid cross-threading, jamming, or fitting wear
- Universal compatibility with major OEM beer systems
Whether you’re selling refillable growler kits or servicing restaurant towers, a poorly cut thread or minor gas leak can damage equipment — and brand reputation.
4. Burst Strength = Transport + Tap Safety
Beer cartridges operate under high pressure. Uneven wall thickness or material flaws can cause bursting in hot kitchens, beer trucks, or air freight. We test every batch to meet or exceed 200–250 bar burst pressure, with uniform cold-rolled steel stamping — not welded pipes.
5. Anti-Corrosion Finish = Humid Bar & Kitchen Protection
Beer cartridges are often stored near sinks, refrigerators, or mobile coolers. Unprotected surfaces may rust, flake, or affect sanitation. We apply a zinc/nickel anti-rust coating + steam-cleaned finish, ensuring your cartridges stay clean and durable throughout the supply chain.
6. Packaging Quality = Shelf Impact + Export Safety
In the beer industry, first impressions matter. That’s why we use:
- Moisture-resistant cartons
- Stack-safe box construction
- Custom-branded or neutral retail kits
- Inner tray options for growler kits or tap bundles
Well-packaged cartridges not only survive transit — they impress customers on arrival.
Bottom line: If you’re selling beer CO2 cartridges, small flaws in thread, finish, or filling can cause real damage to foam quality, keg pressure, and brand trust. That’s why our production line integrates quality control into every stage — not just after sealing.
Safe Storage for Beer CO2 Cartridges — What Wholesale Buyers Should Know
Beer CO2 cartridges are used in bars, growler kits, and kegerator systems — often stored near wet prep zones, cold rooms, or transport crates. While compact, they’re still pressurized Class 2.2 gas containers, and improper storage can affect both safety and brand presentation.
Here’s what beer industry buyers should always keep in mind:
- Store away from heat, sunlight, or draft system cleaning areas
- Avoid stacking cartons near wet floors, sinks, or glycol chillers
- Keep outer packaging clean and dry — rust spots or damaged labels can reduce brand value
- Use FIFO rotation and clearly label different thread types or SKUs

Why CO2 Cartridges Matter in Beer Dispensing
CO2 isn’t just for pushing beer out of a keg — it’s a critical part of how your beer tastes, pours, and stays fresh. If you’re supplying draft systems, growler kits, or taproom accessories, understanding the role of CO2 helps you choose and recommend the right cartridge for every pour.
1. CO2 Preserves Beer Freshness
Once beer is opened or kegged, oxygen exposure causes flavor degradation. CO2 acts as a protective layer, preventing oxidation and keeping the beer crisp and clean-tasting for days — even weeks.
2. CO2 Provides Pouring Pressure
Beer needs to be pushed from the keg to the tap — and gravity isn’t enough. CO2 cartridges provide consistent internal pressure, ensuring:
- Smooth, stable flow through the draft line
- Adjustable serving force based on beer style and system length
- No foaming due to pressure drops
3. CO2 Maintains Carbonation Level
Without gas support, even well-brewed beer can go flat after a few pours. Cartridges help maintain the beer’s natural carbonation level, delivering:
- Proper mouthfeel and texture
- Foam head retention
- The sensory “bite” expected from lagers, IPAs, and wheat beers
4. CO2 Enables Portability
In growler systems, mini-kegs, and beer trucks, pressurized CO2 cartridges offer:
- A compact, refillable solution to carry carbonation anywhere
- Consistent performance without needing a full gas cylinder
- Freedom to serve on tap at outdoor events, festivals, or mobile bars
Whether you’re building a new beer system brand or sourcing for hospitality kits, CO2 cartridges are the hidden engine behind every perfect pint.
What Tools Work with Beer CO2 Cartridges?
Beer CO2 cartridges (8g / 16g / 74g) are only part of the draft equation — they’re designed to power growler kits, kegerators, tap heads, and more. If you’re building a draft system brand or supplying beer accessory kits, bundling the right tools helps maximize both functionality and perceived value.
Here are the most commonly paired accessories for beer dispensing cartridges:
1. CO2 Regulators for Draft Systems
Regulators are critical for controlling carbonation and flow rate in beer systems. They attach to the cartridge and manage PSI output to avoid overfoaming or flat beer.
✔ Compatible with 3/8″, 1/2″, and 5/8″ threaded cartridges ✔ Available in inline, mini, and dial-gauge formats ✔ Often bundled with portable growler kits or mini-keg systems
2. Stainless Steel Growlers and Mini Kegs
Growlers use pressurized cartridges to keep beer fresh on tap — even when mobile. These containers often include:
✔ Cartridge ports with built-in holder ✔ Tap towers, pressure valves, and rubber gaskets ✔ Perfect for outdoor use, tastings, or draft refill stations
3. Portable Tap Kits (with Lines and Faucets)
For bars or events, these kits convert kegs or growlers into full-service taps.
✔ Designed for use with 16g or 74g cartridges ✔ Modular and refillable ✔ Ideal for on-the-go pouring at festivals, beer trucks, or pop-ups
4. Threaded Adapters and Hose Fittings
Make your cartridge compatible with a variety of beer equipment using:
✔ 3/8″ to 1/2″ or 5/8″ adapters ✔ Quick-connect couplers ✔ Inline check valves to prevent backflow
