Drinkmate OmniFizz — Carbonate Any Beverage
Unlike standard SodaStream machines, the Drinkmate OmniFizz is designed to safely carbonate any liquid — juice, wine, cocktails, cold brew — not just water. Uses standard 60L CO₂ cylinders and third-party refills.

What You Need
Three components beyond your existing SodaStream machine:
| Component | Purpose | Approx. Cost |
|---|---|---|
| 5 lb CO₂ aluminum tank | Main reservoir — holds ~5.5x a SodaStream 60L cylinder | $30–$50 |
| CGA-320 regulator | Reduces tank pressure (~850 PSI) to usable levels | $35–$60 |
| SodaStream adapter hose | Connects regulator output to SodaStream bottle port | $15–$25 |
Total upfront: approximately $80–$135. Use the CO₂ Cost Calculator to determine your break-even timeline.
Step-by-Step Setup
- Purchase a filled 5 lb CO₂ tank from a homebrew shop or gas supplier. Confirm food-grade CO₂. Note tare weight stamped on the collar for future reference.
- Attach the CGA-320 regulator to the tank valve. Thread clockwise; hand-tighten, then snug with a wrench. Apply PTFE thread tape to regulator inlet threads if needed.
- Connect the adapter hose from regulator output to the SodaStream machine's carbonation port. Some adapters replace the cylinder entirely; others pass through a hose from the cylinder port.
- Open the tank valve slowly — counterclockwise, no more than one full turn. Check all connections with soapy water. No bubbles means a good seal.
- Test with cold water. Operate the SodaStream normally. If it carbonate as expected, the setup is complete.
⚠️ Safety Reminders
Keep the tank upright and secured at all times. Turn the tank valve off when not in use. Check all connections monthly with soapy water. See the CO₂ Safety Guide for full storage guidance.
Is the Upgrade Worth It?
| Daily Usage | Cylinders/Year | SodaStream Cost | 5 lb Tank Cost | Break-Even |
|---|---|---|---|---|
| 0.5L/day | ~3 | $45–$60/yr | $8–$12/yr + $100 hardware | ~2.5 years |
| 1L/day | ~6 | $90–$110/yr | $15–$18/yr + $100 hardware | ~12–14 months |
| 1.5L/day | ~9 | $135–$165/yr | $22–$28/yr + $100 hardware | ~8–10 months |
| 2L+/day | 12+ | $180–$215/yr | $28–$35/yr + $100 hardware | ~6–8 months |
At 1L+/day, the upgrade pays for itself within a year and saves $80–$150 per year after that. At under 0.5L/day, the convenience of retail exchange may outweigh the savings.
FAQ
Does using a 5 lb tank void my SodaStream warranty?
SodaStream states using non-official cylinders voids the machine warranty. This is a business position. Physically, the CGA-320 adapter connects identically to an official cylinder. For machines more than a year old, most users find the ongoing savings worth the consideration.
Can I use a 10 lb tank instead?
Yes — the connection is the same. A 10 lb tank holds twice the CO₂ and means half as many refill trips. The practical constraint is size: approximately 26 inches tall, which may not fit conveniently in a kitchen space.
Where do I get the 5 lb tank filled?
Homebrew supply shops fill on the spot for $10–$18. See our complete refill guide for all options by location type.
Can I use this setup for kegging beer as well?
Yes — a 5 lb tank with a dual-gauge regulator (one gauge for tank pressure, one for output) is the standard entry-level keg carbonation setup. Add a ball-lock keg and a short gas-in hose and you have a complete home kegging system. The same tank serves both your sparkling water and your beer keg.
