Waterloo made a name for itself with bold branding and a lineup that spans fruit, citrus and plain options. Seven flavors come up most often in conversation, and each occupies a slightly different spot on the sweet-to-tart spectrum. This guide sorts them from least to most broadly appealing so you can plan a stock-up or a party cooler without second-guessing.
What Counts in This Ranking
The order below follows four factors that apply to any flavored sparkling water, rather than anyone’s personal palate.
- Flavor profile: how distinct and well-balanced the named flavor is likely to read.
- Versatility: flexibility for sipping, food pairing and mixing.
- Broad appeal: how many types of drinkers will probably enjoy it.
- Availability: how frequently the flavor appears in common retail packs.
Keep in mind that lineups differ by region and season, and the brand rotates limited flavors occasionally.
The Countdown
7. Blackberry
Blackberry has a deep, slightly tart fruit character that sets it apart from the citrus-focused flavors. It is attractive for people who want a berry note without sweetness overload. Its narrower following puts it at the bottom of this broad-appeal list.
6. Strawberry
Strawberry is gentle and approachable, with a candy-adjacent aroma that fans of berry drinks tend to enjoy. It is easy to drink on its own, though it may seem mild next to bolder cans. Pairing it with a squeeze of lime adds more contrast.
5. Original
The unflavored option offers the cleanest taste and the biggest range of uses. It is ideal for cocktails, spritzers, or anyone who wants carbonation without added flavor. It ranks mid-table because many shoppers want flavor in the can itself.
4. Lime
Lime delivers a sharp, zesty character that suits people who enjoy a tart finish. It stands in neatly for a lime-and-soda combination at home or at a bar. Its single-note focus keeps it from climbing higher, but it is dependable.
3. Grapefruit
Grapefruit leans bittersweet and refreshing, making it a favorite among citrus fans. It also doubles as a base for tequila-free palomas and spritzers. The slight bitterness is the only barrier for some drinkers.
2. Watermelon
Watermelon offers a light, summery fruit flavor that most people find easy to enjoy. It works at picnics, beach days and backyard gatherings alike. The mild sweetness gives it broad reach among both kids and adults.
1. Black Cherry
Black Cherry is the flavor most strongly associated with the brand, with a rich, soda-like fruit profile in a sparkling-water format. It appeals to fans of cherry cola and fruit candy alike, and it is commonly found in multipacks. Strong recognition and wide appeal earn it first place.
Quick-Reference Table
| Rank | Flavor | Profile | Good For |
|---|---|---|---|
| 1 | Black Cherry | Rich cherry, soda-like | Cherry cola fans |
| 2 | Watermelon | Light, juicy melon | Summer gatherings |
| 3 | Grapefruit | Bittersweet citrus | Mocktails |
| 4 | Lime | Sharp, zesty | Lime-and-soda lovers |
| 5 | Original | Clean carbonation | Mixing, spritzers |
| 6 | Strawberry | Soft, sweet berry | Easy sipping |
| 7 | Blackberry | Deep, tart berry | Berry enthusiasts |
Ways to Use Each Style
Fruit-forward cans can be served straight from the fridge, but a tall glass with ice softens the bubbles for slower sipping. Original works best as a blank canvas: add muddled fruit, herbs, or a splash of juice to build a custom drink. Citrus flavors like Lime and Grapefruit are practical for meals because their acidity cuts through rich or fried foods.
Comparing the Fruit Flavors
One way to understand the lineup is by sweetness impression. Black Cherry and Watermelon sit on the rounder, fruitier end of the range, with aromas that many drinkers associate with candy or soda. Grapefruit and Lime sit on the sharper side, giving a more tart finish that cuts through heavy meals. Blackberry and Strawberry fall in between, offering berry notes without the bitterness of citrus peel.
Original is a different kind of choice entirely. Without any added flavor, it gives you carbonation and a clean palate, which is useful when the drink needs to disappear into a recipe or when you want to flavor it yourself with a squeeze of fresh fruit, a few muddled berries or a drizzle of syrup.
Pairing Waterloo With Food
- Black Cherry: works with barbecue, smoked meats and sweet-spicy sauces.
- Watermelon: suits salads, grilled chicken and light picnic foods.
- Grapefruit: complements seafood, tacos and anything fried.
- Lime: a natural partner for Mexican dishes, noodles and curries.
- Strawberry and Blackberry: pair with cheese boards, desserts and brunch spreads.
Another helpful tactic is to freeze fruit in an ice cube tray and drop the cubes into a glass of sparkling water. As the cubes melt, they release extra flavor without watering the drink down too quickly.
Because availability depends on the retailer and the season, it is worth keeping an eye on what a store has on hand rather than assuming every flavor will be stocked. If a favorite is missing, a similar-profile alternative can fill the gap for a party or a work-week supply.
Shopping Notes
Multipacks are the most economical way to try several flavors, though assortments differ by store. Cans keep best in a cool pantry and should be chilled before serving. If you plan to use the sparkling water in recipes, Original and Lime offer the most flexibility because they add little competing flavor.
In short, Black Cherry and Watermelon deliver the most familiar fruit-forward experiences, Grapefruit and Lime reward drinkers who like a tart finish, and Original is the utility player for recipes. A mixed case covers all three moods.
