What Makes Waterloo Different — The Independent Brand Story
Waterloo launched in Austin, Texas as a direct challenge to what had become a corporate sparkling water category. By the time Waterloo entered the market, La Croix was owned by National Beverage Corp with national distribution, Bubly was PepsiCo’s answer, AHA was Coca-Cola’s entry, and Topo Chico had been acquired by Coca-Cola. The premium sparkling water aisle had become a battleground for billion-dollar conglomerates.
Waterloo’s positioning was explicitly independent and explicitly about flavor quality. The brand uses Non-GMO Project Verified natural flavors — not just “natural flavors” but flavors that have passed third-party GMO-avoidance verification. They source water locally and distribute regionally where possible (each can sold within approximately 500 miles of its source, per the brand). And they pursued certifications that most sparkling water brands haven’t bothered to get: Whole30 Approved, Certified Gluten-Free, Certified Vegan, Kosher.
For a significant portion of buyers, these certifications aren’t marketing checkboxes — they’re the deciding factor. A Whole30 participant who wants carbonated drinks during a reset, a Kosher household, a vegan who cares about ingredient sourcing — Waterloo clears hurdles that La Croix and Bubly don’t even attempt.
Ingredients and Certifications — What’s Actually Verified
Every Waterloo flavor contains two ingredients: purified carbonated water and Non-GMO Project Verified natural flavors. Zero calories, zero sugar, zero sweeteners, zero sodium — one of the cleaner label profiles of any mainstream sparkling water.
The certifications deserve individual explanation because they’re not all equivalent:
The Butterfly certification requires that all inputs — including the natural flavor extracts — come from non-GMO sources and are verified by a third-party auditor. Waterloo specifies that flavors are derived from vegan sources. Most other sparkling water brands use natural flavors without this verification.
The Whole30 program certifies products that contain no added sugars, sweeteners, alcohol, grains, dairy, or legumes. Waterloo qualifies cleanly — water and plant-derived flavors only. La Croix and Bubly are technically Whole30-compatible but don’t carry official Approval.
Third-party certification confirms no animal products, animal-derived ingredients, or animal testing. Relevant for vegan buyers who want certification rather than assuming. Most sparkling waters are de facto vegan but don’t carry independent verification.
Third-party verification that the product contains no gluten — relevant for celiac and gluten-intolerant consumers who want a certified rather than assumed gluten-free product.
Rabbinical certification confirming compliance with Jewish dietary laws. Relevant for Kosher-observant households and institutions that require certified products rather than unlabeled ones.
BPA Non-Intentional means BPA was not intentionally added to the can lining — the standard for modern aluminum cans. Not unique to Waterloo but worth noting alongside the other certifications.
PFAS Transparency — Honest About What We Know and Don’t
Waterloo was not included in Consumer Reports’ September 2020 PFAS bottled water test — the most widely cited independent dataset for sparkling water PFAS levels. Unlike La Croix (1.16 ppt), Bubly (2.24 ppt), or Topo Chico (9.76 ppt before filtration improvements), there is no publicly available independent third-party ppt measurement for Waterloo.
What we do know:
Waterloo’s official position: Their FAQ states the water undergoes “a robust multi-step filtration process to ensure our locally sourced water is purified and any contaminants are removed.” The brand uses purified (not spring) water, meaning it passes through filtration that would typically capture PFAS compounds, unlike untreated spring sources.
2024 update: A Waterloo representative communicated to consumer health researchers that the company had switched to a “non-chemical alternative” in their production process in 2024 — the specific context was a PFAS-related discussion, suggesting the brand was proactively addressing filtration. The exact nature of this change was not publicly detailed.
The honest limitation: Without published independent third-party PFAS testing, no specific ppt level for Waterloo can be confirmed. For PFAS-conscious buyers who want a number, Waterloo currently can’t provide one in the same way La Croix can point to Consumer Reports’ 1.16 ppt result.
All Waterloo Flavors Ranked — Best to Try First
1. Grape — The Standout That Makes Converts
Waterloo Grape does what no other sparkling water brand has reliably managed: deliver an authentic, genuinely grape-forward flavor without tasting artificial. The grape profile is rich, slightly sweet, and immediately recognizable as the real fruit — not grape candy, not grape juice concentrate, not grape medicine. It’s the single most-cited reason people switch from La Croix to Waterloo, and it’s been the brand’s bestseller since launch. If you haven’t tried Waterloo, start here.
2. Summer Berry — Bold Mixed Berry
A proprietary mixed-berry blend that leans toward blackberry and raspberry. Bold and present without being sweet. Among the best berry sparkling waters on the market alongside Bubly Blackberry. Available widely and consistently, making it a reliable daily option once you’ve tried Grape and want a second regular flavor.
3. Mango — Tropical Done Right
Warm, tropical, and forward — similar profile to Bubly Mango but with slightly stronger carbonation that gives the tropical flavor more backbone. For mango fans choosing between the two, it’s a close call; Waterloo’s version is marginally bolder, Bubly’s slightly smoother.
4. Strawberry — Genuine Fresh Fruit Profile
Fresh, bright strawberry without the medicinal aftertaste that ruins most sparkling water strawberry options. Pairs excellently with the stronger carbonation — the fruit flavor holds up through the bubbles instead of disappearing. Second choice for many Waterloo regulars.
5. Pineapple Coconut — The Unique Entry
No other major sparkling water brand has executed this combination successfully. Waterloo’s Pineapple Coconut captures the tropical combination without veering into sunscreen-scented territory. The coconut is subtle — present but not overwhelming. If you like tropical and want something no one else makes well, this is worth trying.
6. Watermelon — Summer Standard
Bright, melon-forward, refreshing in warm weather. Competitive with Bubly Watermelon — similar profile, slightly stronger carbonation. A reliable warm-weather pick rather than a year-round staple for most drinkers.
7. Cherry Limeade — The Complex Option
A combination flavor that works better than most sparkling water combo attempts. Cherry and lime together create a slightly sweet-tart profile similar to a virgin cocktail. Unique in the Waterloo lineup and in the broader sparkling water category — no close equivalent from La Croix or Bubly.
8. Grapefruit — Strong but Not Topo Chico
Bold grapefruit with some of the bitterness the real fruit has. Better than La Croix Pamplemousse for actual grapefruit flavor, not quite as mineral-complex as Topo Chico or Spindrift’s real-juice version. A solid pick for citrus fans.
9-12. Black Cherry, Lemon, Lime, Orange Cream
The remaining core flavors. Black Cherry is deeper and less sweet than Cherry Limeade. Lemon and Lime are reliable classics — clean citrus without complexity. Orange Cream is the most unusual flavor conceptually (tastes like a sparkling orange creamsicle) and is either exactly what you’d want or surprising in an unwelcome way — worth a single-can trial before buying a pack.
Carbonation Profile — Where Waterloo Sits
Waterloo markets itself on “lively carbonation” — and the claim holds up. Among the major sparkling water brands reviewed on this site, Waterloo’s carbonation profile sits roughly as follows:
| Brand | Carbonation Level | Bubble Persistence |
|---|---|---|
| Topo Chico | Very high (most aggressive) | Very long-lasting |
| Perrier | High | Long-lasting |
| Waterloo | Medium-high | Good |
| La Croix | Medium | Moderate |
| Spindrift | Medium | Moderate |
| Bubly | Light-medium (softest) | Shorter |
Waterloo sits between La Croix and Perrier — more assertive than La Croix’s medium-level carbonation but not as aggressive as Topo Chico. For people who find La Croix’s bubbles too flat but Topo Chico too intense, Waterloo is often the natural landing point.
Waterloo vs La Croix vs Bubly — Where Each Wins
| Factor | Waterloo | La Croix | Bubly |
|---|---|---|---|
| Ownership | Independent (Austin TX) | National Beverage Corp | PepsiCo |
| Non-GMO Certified | ✅ Yes | ❌ No | ❌ No |
| Whole30 Approved | ✅ Yes | ❌ No | ❌ No |
| Sodium | Zero | Near-zero | Near-zero |
| Carbonation | Medium-high | Medium | Light-medium |
| PFAS data | Limited (not in CR test) | 1.16 ppt (2020) | 2.24 ppt (2020) |
| Standout flavors | Grape, Pineapple Coconut | Pamplemousse, Limoncello | Mango, Strawberry |
| Price per 12-pack | $5-7 | $5-9 | $5-8 |
Pricing & Where to Buy
Waterloo is available at Whole Foods, Target, Walmart, HEB, Kroger, Sprouts, and online via Amazon. Pricing:
- 12-pack (12 oz) — $5.00-7.00
- 24-pack — $10-14

Waterloo is priced comparably to La Croix and Bubly despite carrying more certifications — the brand has not used its certification stack to justify a premium price point, which works in the buyer’s favor.

Grape flavor is unlike anything else in sparkling water. Tastes like actual grape without tasting fake. Converted from La Croix and never looked back.
James K. — Canada · 7 May 2026 · ★★★★★
Whole30 approved was the deciding factor for my reset. Waterloo got me through 30 days without missing soda once. The carbonation is noticeably bolder than La Croix.
Priya M. — UK · 3 May 2026 · ★★★★☆
PFAS transparency section appreciated. The honest “limited independent data” admission is more trustworthy than brands claiming perfect scores without showing their work.
Sam W. — Australia · 28 Apr 2026 · ★★★★★
Pineapple Coconut is the most interesting flavor in sparkling water. No one else has done this combination well. Waterloo nailed it.
Ana C. — USA · 24 Apr 2026 · ★★★★☆
Non-GMO, Whole30, Vegan, GF, Kosher — I have a list of restrictions and Waterloo is the only sparkling water that clears all of them. The mango flavor is genuinely good too.

The Bottom Line
Waterloo earns its place in the sparkling water conversation by doing two things better than its bigger-brand competitors: delivering genuinely bold, authentic flavors (Grape is the best in the category; Pineapple Coconut is uniquely theirs) and carrying the deepest certification stack of any major sparkling water — Non-GMO, Whole30, Vegan, Gluten-Free, and Kosher. The trade-off is PFAS transparency: without published independent third-party testing data, PFAS-conscious buyers can’t get the same specific ppt number they can from La Croix or Topo Chico. For buyers with dietary certifications as a priority, Waterloo is the clear choice — nothing else in the mainstream market matches its certification depth at a comparable price. For buyers choosing primarily on flavor, Waterloo’s Grape alone is worth a trial case. For buyers who need the most published PFAS data or the widest flavor selection, La Croix still edges ahead on those specific metrics. Buy them both once — the comparison makes the decision obvious.
