Which Bubly drops and flavor drops for seltzer are best?
The Six-Flavor Variety Pack is the best starting point for most buyers because it offers six Bubly flavors in one pack. Single-flavor bottles and sweetened enhancers suit narrower preferences.
Bubly Drops Six-Flavor Variety Pack: Best for trying several fruit flavors
- Six flavors
- Unsweetened natural flavor essence
- No calories or sweeteners
- About 36 cans per bottle
Six fruit flavors make it easy to find a favorite without adding sweeteners or calories. Each bottle makes about 36 cans when prepared as directed.
Pros
- Six distinct fruit flavors
- No calories or sweeteners
- Designed for SodaStream sparkling water
Cons
- Made for SodaStream sparkling water
- Flavor choice is limited to the six included
The original variety pack has Strawberry, Grapefruit, Blackberry, Lime, Mango and Cherry. Each bottle makes about 36 cans of flavored sparkling water when prepared as directed.
Because the drops have no calories or sweeteners, the flavor stays closer to an unsweetened seltzer than a soda. This makes the pack a useful first choice when you don't yet know which flavor you'll reach for most.
Add the drops to your SodaStream sparkling water after carbonation. If you're also choosing a machine, our SodaStream starter kit guide explains what first-time buyers can compare.
Bubly Drops New Flavors Variety Pack: Best for trying Bellini Bliss
- Six flavors
- Includes Bellini Bliss and Strawberry Sunset
- Unsweetened natural flavor essence
- About 33 cans per bottle
This six-bottle mix adds Bellini Bliss and Strawberry Sunset alongside Blackberry, Lime, Mango and Cherry. Its unsweetened, zero-calorie format fits buyers looking for Bubly flavors for SodaStream.
Pros
- Two newer flavor names in the mix
- No calories or sweeteners
- Six flavors in one pack
Cons
- Still intended for SodaStream sparkling water
- The pack does not include Strawberry or Grapefruit
The newer variety pack includes Bellini Bliss and Strawberry Sunset, along with Blackberry, Lime, Mango and Cherry. It keeps the same unsweetened, zero-calorie format as the other Bubly Drops here.
This pack makes sense if the two newer flavor names interest you more than the Strawberry and Grapefruit in the original mix. Each bottle makes about 33 cans when prepared as directed.
The directions for this pack call for 1/2 teaspoon in 1 L of freshly fizzed SodaStream water, and say to dilute before drinking. Use those directions as your starting point.
Bubly Drops Berry Bliss Variety: Best for a berry-focused mix
- Three flavors
- Unsweetened natural flavor essence
- No calories or sweeteners
- About 12 liters per bottle
A three-flavor berry assortment suits buyers who want less variety than the six-bottle packs but prefer berry notes. Each bottle makes about 12 liters of sparkling water.
Pros
- Berry-focused assortment
- No calories or sweeteners
- About 12 liters per bottle
Cons
- Flavor names within the variety are not specified
- Designed for SodaStream sparkling water
Berry Bliss is a three-flavor variety for buyers who want a berry-focused pack. The specific flavor names within the mix aren't specified, so choose it for the berry theme rather than for a particular fruit.
Each 40 ml bottle makes about 12 L of sparkling water. Like the other Bubly Drops, this is an unsweetened essence designed to be added to SodaStream water.
Bubly Drops, Lime: Best for a crisp citrus note
- Lime flavor
- Unsweetened natural flavor essence
- No calories or sweeteners
- About 12 liters per bottle
Lime keeps the flavor choice simple for anyone who already knows what they like. The drops add unsweetened flavor essence to SodaStream sparkling water.
Pros
- Single named flavor
- No calories or sweeteners
- About 12 liters per bottle
Cons
- No flavor variety in the pack
- Made for SodaStream sparkling water
The Lime pack is the most direct pick if you already know you like lime in sparkling water. It contains three bottles of one flavor, each making about 12 L.
This is simpler than buying a variety pack, but it also commits you to Lime across the pack. The drops have no calories or sweeteners, and they're intended for SodaStream sparkling water.
Bubly Drops, Cherry: Best for a familiar fruit flavor
- Cherry flavor
- Unsweetened natural flavor essence
- No calories or sweeteners
- About 12 liters per bottle
Cherry offers a familiar fruit choice in a three-bottle pack. It keeps the Bubly unsweetened format for buyers who want flavor without calories or sweeteners.
Pros
- Single named flavor
- No calories or sweeteners
- About 12 liters per bottle
Cons
- No flavor variety in the pack
- Made for SodaStream sparkling water
Cherry is a single-flavor option in a three-bottle pack. Choose it when you want a familiar fruit note and don't need several flavors in the same box.
Each bottle makes about 12 L of sparkling water. The unsweetened format preserves a plain seltzer base with a cherry essence, rather than adding a sweetener.
Bubly Drops, Blackberry: Best for a berry flavor on repeat
- Blackberry flavor
- Unsweetened natural flavor essence
- No calories or sweeteners
- About 12 liters per bottle
Blackberry is a focused choice for anyone who already knows they want that flavor. It adds unsweetened natural flavor essence to SodaStream sparkling water.
Pros
- Single named flavor
- No calories or sweeteners
- About 12 liters per bottle
Cons
- No flavor variety in the pack
- Made for SodaStream sparkling water
Blackberry is another focused option for buyers who want one fruit flavor on repeat. It is an unsweetened natural flavor essence, and each bottle makes about 12 L.
The three-bottle format is less flexible than a variety pack, so it's best for someone who already knows Blackberry suits their taste. Add it to SodaStream sparkling water as directed.
Bubly Drops, Grapefruit: Best for a bright citrus choice
- Grapefruit flavor
- Unsweetened natural flavor essence
- No calories or sweeteners
- About 12 liters per bottle
Grapefruit suits buyers who want one citrus flavor rather than a variety pack. Each bottle makes about 12 liters when added to SodaStream sparkling water.
Pros
- Single named flavor
- No calories or sweeteners
- About 12 liters per bottle
Cons
- No flavor variety in the pack
- Made for SodaStream sparkling water
Grapefruit is the single-flavor choice for buyers who prefer a citrus note. The pack contains three bottles, with each bottle making about 12 L of sparkling water.
Like the other Bubly Drops, it has no calories or sweeteners. Choose it instead of the original variety pack if Grapefruit is the flavor you already know you want.
Stur Soda Machine Flavors Variety Pack: Best for sweetened flavor variety
- Five bottles
- Sweetened with stevia
- Zero sugar and calories
- Can be added to sparkling water
Stur is a flexible pick if you want a sweetened water enhancer rather than Bubly's unsweetened essence. It can flavor sparkling water, with the amount adjusted to taste.
Pros
- Can be used with sparkling water
- Sweetened with stevia
- Customizable amount
Cons
- Contains a sweetener
- Flavor notes are not specified here
Stur is the better fit if you want a sweetened enhancer that can go into sparkling water. It uses stevia and is described as zero sugar and zero calories.
The amount is customizable, so you can adjust the flavor strength to your taste. Unlike Bubly Drops, Stur isn't an unsweetened essence, which matters if you want the taste of plain seltzer with only fruit flavor.
Allways Drops Cream Soda Water Enhancer: Best for cream soda flavor
- Cream soda flavor
- Sweetened with monk fruit
- Zero sugar and calories
- Works with sparkling water
Allways offers a sweetened cream soda style for buyers who want a soda-like flavor in sparkling water. It uses monk fruit and is described as zero sugar and zero calories.
Pros
- Specific cream soda flavor
- Sweetened with monk fruit
- Can be used with sparkling water
Cons
- Sweetened, unlike Bubly Drops
- One flavor in this pick
Allways Cream Soda is a soda-style option for buyers who want a sweeter flavor than Bubly's fruit essences. It is described as zero sugar and zero calories, and uses monk fruit as its sweetener.
The directions suggest 1–2 squeezes in 8 oz of water, and it can be used with still or sparkling water. Choose this when cream soda flavor matters more than keeping the drink unsweetened.
How did we compare Bubly drops?
We compared the stated flavors, pack formats, sweetness, and how each enhancer is intended to be used. The top Bubly picks rank higher because their unsweetened format directly fits the search for Bubly drops.
The scores weigh specs and features against what you're shopping for.
Bubly Drops are built around SodaStream sparkling water, while Stur and Allways are broader water enhancers that can also be added to sparkling water. The key choice is whether you want unsweetened fruit essence or a sweetened soda-style drink.
What should you check before choosing flavor drops?
Choose a variety pack if you haven't settled on one flavor, or a single-flavor pack if you know what you'll drink. Check whether you want sweetener, too, because Bubly Drops, Stur and Allways differ on that point.
Flavor mix: The original pack has six named flavors, while the newer pack includes Bellini Bliss and Strawberry Sunset. Single bottles keep the choice focused on Lime, Cherry, Blackberry or Grapefruit.
Sweetness: Bubly Drops have no sweeteners. Stur uses stevia, and Allways Cream Soda uses monk fruit, so those options suit a different taste preference.
Use directions: The Bubly products are designed for SodaStream sparkling water. Stur and Allways can be added to still or sparkling water, but follow each product's directions for amounts and dilution.
Pack size: The variety packs offer several flavors, while the single-flavor bottles repeat one taste. Each single Bubly bottle is described as making about 12 L; the variety pack bottles make about 36 cans, except the new flavors pack, which makes about 33 cans.
Are Bubly Drops the right choice for your seltzer?
Choose Bubly Drops if you want unsweetened flavor essence for SodaStream sparkling water, and pick the original variety pack when you want the most named flavor options. Choose Stur for a stevia-sweetened enhancer, or Allways Cream Soda for a monk-fruit-sweetened soda flavor.
If you want to make a sweeter drink at home, our Italian soda guide has a simple recipe path. For a plain sparkling water setup, compare carbonated water makers before buying a machine.

What are Bubly Drops?
Bubly Drops are unsweetened flavor essences for SodaStream sparkling water. The varieties here contain no calories or sweeteners, and the multi-flavor packs let you choose a taste such as Lime, Cherry or Blackberry.

Stur and Allways are alternatives if you want a sweetened sparkling water enhancer.
Stur uses stevia, while Allways Cream Soda uses monk fruit.
Can you use Bubly Drops without a SodaStream?
The Bubly Drops in this guide are made to flavor SodaStream sparkling water. If you use another sparkling water maker, check its instructions and the flavor product directions before adding anything.

How do you make Bubly sparkling water with drops?
Fizz plain water first, then add Bubly Drops according to the directions for that pack. The new flavors pack describes using 1/2 teaspoon in 1 L of freshly fizzed water and says to dilute before consuming.
