Best SodaStream flavors for your usual drink

The best SodaStream flavors start with the soda you already enjoy: Pepsi Zero Sugar for cola, the Zero Variety Pack for fruit choices, and Starry Zero for caffeine-free lemon-lime. Buy for your taste and caffeine needs before comparing pack sizes.

These are drink mixes added after carbonation, so flavor strength and fizz are separate choices. You can make a lightly flavored drink without giving up bubbles, or a stronger soda without changing your machine's carbonation routine.

RosyRoutine compared flavor options, nutrition details and pack contents. The top-ranked cola won't suit every household, so each pick below explains who should choose it and who should pass.

Which SodaStream flavors suit different tastes?

Choose cola, citrus, pepper-style soda, MUG soda or fruit blends first, then narrow the choice by caffeine and sweetener preferences. A familiar flavor in a larger pack is useful for regular drinkers; a variety pack makes more sense when preferences are unsettled.

Pepsi Zero Sugar leads for cola fans, but a lower-ranked caffeine-free mix may fit your routine better. The comparison below shows the pack differences before the individual buying advice.

1

SodaStream Pepsi Zero Sugar Drink Mix

Best for Pepsi Zero fans

8.9/10Our score

• Zero sugar and zero calories
• 37 mg caffeine per 12 fl oz
• 4 bottles, about 96 drinks
• Adjustable flavor strength

Choose this pack if Pepsi Zero Sugar is the cola you already prefer. Four bottles of one flavor suit repeat drinkers better than households still choosing a favorite.

See it on Amazon

Pros

• Familiar Pepsi Zero Sugar flavor
• Zero sugar and calories
• Adjustable flavor strength

Cons

• Contains caffeine
• Four bottles of one flavor

Pepsi Zero Sugar is the strongest starting point for someone who already chooses Pepsi Zero over other colas. It brings that named cola flavor to homemade sparkling water with zero sugar and zero calories.

This isn't the pack to buy just because it ranks first. If Diet Pepsi is your usual choice, stay with that flavor rather than expecting all sugar-free colas to be interchangeable.

The mix contains 37 mg of caffeine per 12 fl oz, so skip it if you're building a caffeine-free drinks shelf. A smaller serving changes how much you drink, but it doesn't make the mix caffeine free.

For a repeat cola drinker, four bottles of the same flavor keep the choice simple. For a household that wants a different drink each day, those repeated bottles are a reason to choose variety instead.

Measure your first glass rather than pouring by eye. Once you find a strength you like, keeping the same water volume and syrup measure makes later drinks easier to repeat.

2

SodaStream Zero Variety Drink Mix

Best for undecided fruit drinkers

8.7/10Our score

• Lemonade, pink grapefruit, strawberry watermelon and cranberry raspberry
• 4 bottles, about 96 drinks
• No HFCS or aspartame
• Naturally flavored

This pack gives you four fruit choices without committing to four bottles of one flavor. It suits households that want to compare flavors or rotate drinks.

See it on Amazon

Pros

• Four different fruit flavors
• No high-fructose corn syrup or aspartame
• Adjustable flavor strength

Cons

• No cola option
• Only one bottle of each flavor

The Zero Variety Pack is the better buy for a household still choosing its favorite fruit drink. It includes lemonade, pink grapefruit, strawberry watermelon and cranberry raspberry, with one bottle of each.

That spread lets you compare different fruit directions without buying several single-flavor packs. It also gives household members separate choices from the same purchase.

The mixes are naturally flavored and contain no high-fructose corn syrup or aspartame. Those details don't establish the full sweetener formula or exact sugar and calorie amounts, so check the nutrition panel if those decide your purchase.

Skip this pack if you only want lemonade or already know you dislike several of the included flavors. Unused bottles reduce the benefit of buying variety.

Try each flavor on its own before combining them. If you're also setting up a home soda station, our guide to choosing a sparkling water maker covers the machine choices that sit alongside your flavor decision.

3

SodaStream Diet Pepsi Drink Mix

Best for Diet Pepsi regulars

8.6/10Our score

• Zero sugar and zero calories
• 4 bottles, about 96 drinks
• Adjustable flavor strength
• Diet Pepsi flavor

Pick Diet Pepsi if its flavor is already your preference over Pepsi Zero Sugar. The concentrate lets you choose the strength of each drink.

See it on Amazon

Pros

• Diet Pepsi flavor
• Zero sugar and calories
• Adjustable flavor strength

Cons

• Four bottles of the same cola
• Confirm caffeine information if needed

Diet Pepsi is the right choice for a regular Diet Pepsi drinker, even though Pepsi Zero Sugar ranks above it here. Your preferred cola matters more than a small score gap.

It has zero sugar and zero calories, and you can adjust the concentrate to make a lighter or stronger drink. Start at the directed ratio so you can judge the flavor before changing it.

Choose this pack when you want to replace a familiar diet cola routine with drinks mixed at home. Skip it if you're hoping for fruit variety or a pepper-style dark soda.

If avoiding caffeine is a firm requirement, confirm the caffeine information before choosing this mix. MUG Zero and Starry Zero are the confirmed caffeine-free options in this group.

Keep your water volume consistent while adjusting the syrup. Changing both at once makes it harder to tell whether a disappointing glass needs more flavor or simply less dilution.

4

SodaStream Mountain Dew Zero Drink Mix

Best for caffeinated citrus drinkers

8.5/10Our score

• Zero sugar and zero calories
• 48 mg caffeine per 12 fl oz
• 4 bottles, about 96 drinks
• Adjustable flavor strength

Mountain Dew Zero suits buyers who want its bold citrus soda flavor rather than cola or lemon-lime. Choose another mix if caffeine-free drinks are your priority.

See it on Amazon

Pros

• Mountain Dew Zero Sugar flavor
• Zero sugar and calories
• Adjustable flavor strength

Cons

• Contains caffeine
• One flavor throughout the pack

Mountain Dew Zero is for buyers who want Mountain Dew's bold citrus soda flavor, rather than cola or a lemon-lime drink. Choose it because that flavor is your preference, not simply because you want something fruity.

It has zero sugar and zero calories, with 48 mg of caffeine per 12 fl oz. That caffeine content makes it a different choice from Starry Zero, even though both belong on the citrus side of the shelf.

Skip this pack if you want a caffeine-free evening drink. It also won't give you the rotating fruit combinations found in either variety pack.

A lighter syrup pour can soften the flavor, but it doesn't turn Mountain Dew into a different citrus soda. If you already prefer lemon-lime, choose that style from the start.

For the first few drinks, adjust one part of the process at a time. Set your preferred fizz with plain water, then work on the syrup amount until the balance suits you.

5

SodaStream Diet Dr Pete Drink Mix

Best for pepper-style soda fans

8.4/10Our score

• Zero calories and sugar free
• Sweetened with sucralose
• No aspartame or HFCS
• 65 mg caffeine per 12 fl oz

Diet Dr Pete offers a pepper-style dark soda for buyers who want an alternative to cola. Its sucralose sweetener suits shoppers specifically avoiding aspartame.

See it on Amazon

Pros

• Pepper-style dark soda flavor
• Zero calories and sugar free
• No aspartame or high-fructose corn syrup

Cons

• Contains caffeine
• Four bottles of one flavor

Diet Dr Pete suits buyers who want pepper-style dark soda rather than another cola. It's a distinct flavor choice, not a reason to expect the taste of a different named brand.

The formula is sugar free and zero calorie, with sucralose and no aspartame or high-fructose corn syrup. That makes it a clear option for someone specifically seeking an aspartame-free dark soda.

It contains 65 mg of caffeine per 12 fl oz, the highest disclosed amount among the mixes compared here. Skip it if your main goal is reducing caffeine or choosing a drink for a caffeine-free routine.

Four bottles of this flavor suit someone who already enjoys pepper-style soda. If you're only curious about the style, consider whether you'll want that much of it before committing.

Measure the concentrate even if you prefer a bold drink. A heavier pour uses the bottle faster and changes the amount of caffeine in the glass along with the flavor strength.

6

SodaStream Mug Root Beer Zero Drink Mix

Best for evening soda

8.0/10Our score

• Zero sugar and zero calories
• No caffeine
• 4 bottles, about 96 drinks
• Adjustable flavor strength

MUG Zero suits soda drinkers who want a caffeine-free option. Serve the prepared soda alone or use it for a soda float.

See it on Amazon

Pros

• Caffeine free
• Zero sugar and calories
• Works as the soda base for a float

Cons

• One soda flavor only
• Four bottles of the same flavor

MUG Zero is the pick for MUG soda fans who want no caffeine. Its zero-sugar, zero-calorie formula also separates the prepared soda from a traditional dessert drink.

Choose it for a soda to serve with a meal or enjoy in the evening without choosing a caffeinated mix. Skip it if your household prefers cola or citrus, since every bottle contains the same MUG soda flavor.

You can also pour the prepared soda over vanilla ice cream for a float. The finished dessert takes on the sugar and calories of the ice cream and any other additions.

Use a roomy glass and pour slowly when making a float, since soda can foam as it meets the ice cream. Keep the carbonation bottle for water and prepared drinks rather than adding dessert ingredients inside it.

Soda residue still needs cleaning even when the mix is sugar free. Follow our guide to cleaning SodaStream bottles to keep flavored drinks from lingering in your next batch.

7

SodaStream Starry Zero Drink Mix

Best for caffeine-free citrus drinkers

7.9/10Our score

• Zero sugar and zero calories
• Caffeine free
• 4 bottles, about 96 drinks
• Pour-spout bottle

Starry Zero is the lemon-lime choice for buyers avoiding caffeine. Its pour-spout bottle helps direct the mix while you measure and pour.

See it on Amazon

Pros

• Caffeine free
• Zero sugar and calories
• Pour-spout bottle

Cons

• Only lemon-lime in the pack
• No fruit variety

Starry Zero is the straightforward choice for caffeine-free lemon-lime soda. Pick it when you want that flavor without the caffeine found in Mountain Dew Zero.

It has zero sugar and zero calories, and its pour-spout bottle helps direct the concentrate while mixing. The spout is a pouring aid, so you still need the correct measure for the amount of water you're flavoring.

This pack suits someone who expects to make lemon-lime regularly. Skip it if you're buying mainly to explore several fruit flavors, because all four bottles contain the same drink mix.

Follow the directions on the flavor bottle rather than borrowing a measure from another syrup. Similar-looking bottles don't make preparation amounts interchangeable.

If several people share a machine, keep plain sparkling water available and flavor separate servings to preference. Our SodaStream bottle sizes guide explains the bottle types before you add extra carbonation bottles to that setup.

8

SodaStream Bubly Burst Drink Mix

Best for fruit blend explorers

7.6/10Our score

• Cherry lemonade, peach mango and watermelon lime
• 3 bottles
• 45 calories per 12 oz serving
• About 72 drinks per pack

Choose Bubly Burst for its three fruit blends if zero calories aren't a requirement. This pack contains three bottles, so compare it with four-bottle packs on equal terms.

See it on Amazon

Pros

• Three different fruit blends
• One bottle of each flavor
• About 24 servings per bottle

Cons

• Not a zero-calorie choice
• Fewer total servings than the four-bottle packs

Bubly Burst suits fruit drinkers who specifically want cherry lemonade, peach mango and watermelon lime. Choose it for those combinations rather than assuming every Bubly-branded drink is the same kind of flavoring.

The prepared drink has 45 calories per 12 oz serving, so skip this pack if zero calories are a firm requirement. That calorie figure doesn't tell you the exact sugar content or sweetener formula.

This pack contains three 440 ml bottles, making about 72 drinks when prepared as directed. It has fewer bottles than the other packs here, which matters when comparing how much concentrate you're bringing home.

The three-flavor format works best when at least two of the combinations appeal to you. If only one sounds useful, a variety pack may leave you with bottles you don't reach for.

Keep flavor selection separate from bottle safety. A bottle that still holds liquid may still need replacing, as explained in our guide to why SodaStream bottles expire.

How should you choose SodaStream flavors?

Choose by flavor, caffeine needs and sweetener preferences, in that order, then decide how much variety you'll use. Pack size becomes useful only after the drink itself fits your routine.

Start with the soda you already choose

Buy your familiar flavor if the goal is replacing a regular soda habit at home. Pepsi Zero Sugar and Diet Pepsi serve different preferences, even though both are sugar-free colas.

Choose MUG soda or pepper-style soda because you enjoy those styles, not because they rank near a cola you like. Adjusting syrup strength changes intensity; it won't turn one flavor into another.

Fruit packs make more sense when you want a change from named sodas. Think about which included flavors you'll actually pour, especially if grapefruit, mango or watermelon divides your household.

Which SodaStream flavors are sugar free?

The confirmed sugar-free choices here are Pepsi Zero Sugar, Diet Pepsi, Mountain Dew Zero, Diet Dr Pete, MUG Zero and Starry Zero. Each is also a zero-calorie option.

Don't use the Zero Variety Pack's name to fill in missing nutrition details. Its lack of aspartame and high-fructose corn syrup doesn't tell you everything else in the formula.

Keep sugar content, calorie content and sweetener choice separate when shopping. If you avoid a particular ingredient, read the ingredient panel rather than using “diet” or “zero” as a shortcut.

Make caffeine a separate decision

Choose MUG Zero or Starry Zero if you need a confirmed caffeine-free option from this group. Flavor color isn't a useful guide: a citrus soda can contain caffeine, while a dark soda can be caffeine free.

Serving size matters too. A large glass prepared at the same ratio contains more concentrate than a smaller one, and extra syrup changes more than the taste.

If one person wants caffeine-free drinks and another wants caffeinated soda, flavor individual servings. That avoids making a shared bottle that doesn't suit everyone.

Choose variety for a reason

Buy a variety pack for exploration or a household with different preferences. Buy repeated bottles of one flavor when you already know what you'll finish.

Consider how often you make soda, not just how many people live at home. An occasional drinker may take much longer to finish a pack than someone who mixes a drink each day.

You don't need to open every bottle immediately to enjoy variety over time. Keep unopened flavors sealed, and follow each bottle's storage and after-opening directions.

How do you mix syrup without losing the fizz?

Carbonate plain water first, then add the flavor slowly after releasing and removing the bottle as your machine directs. Never carbonate water that already contains syrup in a SodaStream machine.

Set up the water and measure first

Start with cold drinking water in a compatible carbonation bottle, filled to its marked water line. Leave the headspace the machine requires rather than filling the bottle to the top.

Carbonate according to your machine's instructions, then allow it to release pressure before removal. Our guide to carbonating water at home explains the basic sequence if you're new to it.

Read the flavor bottle's directions before measuring. Don't assume a full cap or a spoonful is correct for every mix and every water volume.

Add flavor slowly and mix gently

Pour the measured concentrate slowly into the carbonated water, leaving room for foam to rise. Pause if the foam approaches the opening rather than continuing to pour.

Mix gently as directed so the syrup spreads through the water. Vigorous shaking adds mess and makes the bottle harder to open without foam.

For a single glass, use the same mixing ratio scaled to the serving you're preparing. Avoid using a full-bottle measure in a smaller drink.

Adjust flavor and bubbles separately

Change one variable at a time when a drink doesn't suit you. If the flavor is weak but the bubbles are right, change the concentrate amount rather than adding more carbonation.

If the drink is too strong, dilute it with a little plain sparkling water. Still water also dilutes the syrup, but it reduces the fizz at the same time.

If a flavored drink needs more bubbles, don't return it to the machine. Make a fresh batch of plain sparkling water and use that to adjust the drink.

How much syrup will you use each week?

Count measured servings rather than glasses to estimate how long a pack will last. The stated yields assume preparation as directed, and your favorite tumbler may hold more than one serving.

Across these picks, each 440 ml bottle makes about 24 servings. The four-bottle packs provide about 96 drinks, while the three-bottle Bubly Burst pack provides about 72.

As a simple planning example, one directed serving each day uses about seven servings a week. Two people following that routine use about fourteen, before any extra drinks or stronger pours.

A stronger mix uses concentrate faster. A lighter pour stretches the bottle, but buying a flavor you only tolerate when heavily diluted isn't a useful way to choose.

Use prepared volume when comparing packs, and keep the serving sizes consistent. Bottle count alone can hide the difference between a three-bottle purchase and a four-bottle purchase.

How should you store flavors and care for bottles?

Follow each syrup bottle's storage directions, and clean drinking bottles according to their own care instructions. Don't assume all concentrates need the same storage or that every carbonation bottle can go in a dishwasher.

Keep syrup caps secure and wipe sticky drips from the outside of the spout. Use clean measuring tools, and avoid resting a used spoon against the bottle opening.

Note the opening date if that helps you follow any after-opening guidance. Don't invent a shelf-life rule based on a different flavor you've used before.

Rinse drinking bottles after flavored drinks, then wash with a method approved for that bottle. Pay attention to the cap and other areas where drink residue can collect.

Avoid hot water or dishwasher cycles unless the bottle's instructions allow them. Keep an eye on the bottle's condition and replacement date as part of your normal soda routine.

Which mistakes make homemade soda disappointing?

The most avoidable mistakes are guessing the syrup amount, changing several settings at once and buying the wrong flavor style. A consistent first drink gives you a useful starting point.

• Pouring without measuring: It makes flavor strength hard to repeat and uses concentrate at an unknown rate.
• Adding syrup before carbonation: Keep flavored liquid out of a SodaStream machine and flavor the water afterward.
• Using another flavor's dose: Follow the directions for the bottle you're pouring.
• Starting with a large batch: Make a smaller serving at the correct ratio while you decide what strength you prefer.
• Confusing fruit soda with unsweetened flavoring: Check ingredients and nutrition instead of relying on fruit names.
• Blaming syrup for weak bubbles: Resolve carbonation with plain water before adjusting flavor strength.
• Buying for the advertised yield alone: A pack isn't useful if several bottles contain flavors you won't drink.

Once you find a combination you enjoy, remember the water volume, carbonation routine and syrup measure. That simple recipe is more useful than repeatedly trying to correct a glass after pouring.

Which SodaStream flavor should you pick?

Choose Pepsi Zero Sugar for a familiar cola routine, or Diet Pepsi if that's already your preference. For fruit drinks, buy the Zero Variety Pack for its four choices or Bubly Burst specifically for its three blends.

Pick Mountain Dew Zero for caffeinated citrus soda and Diet Dr Pete for pepper-style dark soda. Choose MUG Zero or Starry Zero when caffeine-free dark soda or lemon-lime fits your routine.

The best SodaStream flavors are the ones you'll enjoy at a measured strength and finish without leaving unwanted bottles behind. Start with the directed recipe, then adjust one part of the drink at a time.

If you need an extra bottle for plain sparkling water or separate household flavors, read our guide to SodaStream bottle sizes and types before choosing one.

Frequently asked questions

What are the best SodaStream flavors?

The best SodaStream flavors depend on your usual drink: Pepsi Zero Sugar for cola fans, the Zero Variety Pack for fruit choices, and Mountain Dew Zero for caffeinated citrus soda. Choose MUG Zero or Starry Zero when you want a caffeine-free option, then adjust the mix strength to taste.

How do you add SodaStream flavor?

Carbonate plain water first, release the bottle as your machine directs, then slowly add the measured drink mix; follow the flavor bottle's directions for the amount and mix gently. Never put flavored water back into a SodaStream machine for more fizz; carbonate a fresh batch of plain water instead.

Which SodaStream flavors have no caffeine?

MUG Zero and Starry Zero are caffeine free; Pepsi Zero Sugar, Mountain Dew Zero and Diet Dr Pete contain caffeine, so they don't suit a caffeine-free routine. Don't assume a fruit flavor or a diet label means caffeine free; confirm the caffeine information for the exact mix you choose.

Are all SodaStream flavors sugar free?

No, you shouldn't assume every SodaStream flavor is sugar free; Pepsi Zero Sugar, Diet Pepsi, Mountain Dew Zero, Diet Dr Pete, MUG Zero and Starry Zero are sugar-free choices here. Check the nutrition panel for other mixes, since calorie counts and product names don't establish their sugar content.

How many drinks does one SodaStream flavor bottle make?

Each 440 ml bottle in these packs makes about 24 servings when prepared as directed; that means about 96 drinks from a four-bottle pack and about 72 from the three-bottle Bubly Burst pack. Larger glasses or stronger pours use concentrate faster, so count servings rather than assuming every glass is equal.
