Ingredients, Nutrition & Label Checks

Waterloo keeps it simple: sparkling water + natural flavors, no sugar and no artificial sweeteners. Here’s how the label translates in daily use.

What’s inside (typical can)

0 calories 0 g sugar 0 g carbs Caffeine-free Unsweetened
  • Carbonated water: base for bubbles and bite.
  • Natural flavors: aroma-forward “essences” for fruit character.
  • No sweeteners: no sugar, aspartame, sucralose, or stevia.
  • Very low sodium: typically 0–10 mg per 12 fl oz (check can).

How to read the label (quick scan)

  • Ingredients: “Carbonated water, natural flavors” = clean. Avoid “citric acid” if your teeth are sensitive.
  • Sodium: Under ~20 mg per can is considered low for everyday sipping.
  • Sweeteners: If you see sugar, HFCS, aspartame, sucralose—that’s not Waterloo and not zero-sugar seltzer.
Tip: Chill to 2–5 °C. Aroma compounds pop more when served cold in a wide-mouth glass.

Serving & Mocktail Ideas (Zero-Sugar)

Big aroma = easy wins. Keep it cold, use fresh citrus & herbs, and you’ve got crowd-pleasing sips in under a minute.

Best Serve

  • Temperature: 2–5 °C (very cold).

FAQs & External References

Straight answers about Waterloo’s zero-sugar flavors, ingredients, and everyday use. Links open in new tabs.

Is Waterloo actually zero sugar and zero sweeteners?
Yes. Waterloo is an unsweetened sparkling water: no sugar and no artificial sweeteners. Always verify on the can label: ingredients should read “carbonated water, natural flavors.”
Does Waterloo contain sodium?
Most flavors list 0–10 mg sodium per 12 fl oz. That’s considered very low for daily sipping. Check each flavor panel to confirm.
Is it okay for teeth compared to soda?
Plain, unsweetened sparkling water is far less acidic than sugary sodas. If you have enamel sensitivity, serve it well-chilled and consider avoiding citrus-acid heavy formulas. Rinsing with plain water after sipping is a simple best practice.
Any caffeine or additives I should know about?
Waterloo’s core line is caffeine-free and unsweetened. You shouldn’t see added colors or preservatives on the label. If you do, it’s likely a different product category.
What flavors are best for mocktails?
Lime and Grapefruit are most versatile for citrus-forward mixes. Black Cherry works for dessert-style spritzes. See our Serving & Mocktail Ideas.
Shelf life and storage?
Keep cans cool, out of direct sun, and upright. For best aroma and carbonation, drink by the printed date and serve at 2–5 °C.
