Kegerator vs. SodaStream: What Actually Makes Sense for You

I owned a SodaStream for about two years before I finally built out a kegerator-based carbonation setup in my garage. People ask me constantly which one they should start with, and the honest answer depends entirely on how deep into this hobby you actually plan to go — I regret waiting so long on one front, and I regret not researching harder before I upgraded on the other.

The Real Cost Comparison

A basic SodaStream machine runs roughly $70–$120 upfront, plus CO2 canister exchanges that typically cost around $15–$20 and carbonate somewhere around 60 liters before needing a swap. A basic kegerator-style CO2 setup — tank, regulator, carbonation cap or keg, tubing — runs closer to $250–$500 upfront depending on whether you go with a small 5-lb CO2 tank or a larger 20-lb one, but a 20-lb tank refill costs around $20–$30 and carbonates dramatically more liquid before running out, often the equivalent of many SodaStream canister exchanges.

If you're making soda occasionally — a few liters a week — the SodaStream's lower upfront cost wins easily. If you're making it regularly and in volume, the kegerator setup's cost per liter drops well below the SodaStream's over time, and the breakeven point is usually somewhere in your first year of regular, frequent use.

What SodaStream Actually Does Well

It's genuinely good at what it's built for: fast, simple carbonation of water, which you then flavor separately with syrup. It's compact, it's quiet, and there's essentially no learning curve — I had my first drinkable soda within minutes of unboxing it. If you're testing whether you even enjoy making soda at home before committing real money, this is the right starting point, not a kegerator setup.

What a Kegerator Setup Actually Does Better

A CO2 tank and regulator gives you precise, adjustable pressure control — you're not locked into whatever fixed carbonation level a countertop unit defaults to. That control is what let me actually dial in the specific fizz level I wanted for different recipes, something the SodaStream never offered me. It also scales far better for volume; carbonating a full 5-gallon batch through a keg setup is dramatically more efficient than doing the same volume in a SodaStream's small bottles, one at a time.

What I'd Tell Myself Starting Over

Start with something SodaStream-equivalent if you're not sure this hobby is going to stick — don't let anyone talk you into a $400 kegerator setup before you know you'll actually use it weekly. But if you're already a few months in and finding yourself making soda multiple times a week, don't wait two years like I did. The cost-per-liter math flips in the kegerator's favor faster than people expect, and I spent an unnecessary amount on canister exchanges during year two, after I'd already proven to myself this was a real, ongoing hobby.

FAQ

Is a kegerator setup cheaper than a SodaStream in the long run? For frequent, high-volume soda making, yes — the cost per liter of CO2 is generally lower with a larger tank refill than with SodaStream canister exchanges, though the upfront equipment cost is higher.

Can a SodaStream carbonate soda as strongly as a kegerator setup? SodaStream units typically carbonate to a fixed or limited range of pressure, while a CO2 tank and regulator gives you precise, adjustable control over carbonation level, generally allowing for a wider and more customizable range.

Should a beginner start with a SodaStream or a kegerator setup? A SodaStream or similar countertop carbonator is generally the better starting point for beginners, given the lower upfront cost and minimal learning curve, with a kegerator setup making more sense once you know you'll be making soda regularly.

The Real Lesson

Neither option is objectively better — they're suited to different stages of the same hobby. Start small to prove you'll actually use it, then upgrade once the math and your own habits tell you it's worth it, not before.
