Lemonade without sugar is a harder sell than most people expect. Take the sugar out of lemonade and what’s left is lemon water: tart, a bit sharp, and honestly not what you were hoping for.
But it works if you plan for it. A sugar free lemonade made from fresh lemons and topped with sparkling water is bright, cold and fizzy, and you control the sweetness at the end instead of at the start.
Quick answer: For sugar free lemonade, squeeze 6 lemons into 1 cup of juice, stir it into 3 cups of cold water, and chill. Serve each glass half full of that base, topped with cold sparkling water. Sweeten only if you want to, using a zero-sugar sweetener added a little at a time.
Ingredients
- 6 lemons (1 cup of juice)
- 3 cups cold water
- 3 cups chilled sparkling water
- Zero-sugar sweetener, optional
- Ice, lemon wheels
How to make sugar free lemonade
- Wash the lemons under running water, roll each one on the counter to loosen the juice, then cut and squeeze. Strain out the seeds.
- Combine the juice and 3 cups of cold water in a pitcher.
- Taste it. It will be very tart. If you want sweetness, add your sweetener a little at a time.
- Chill 30 minutes.
- To serve, fill a glass with ice, half fill with the lemon base, and top with sparkling water.
Why serve it with sparkling water?
Fizz and ice take the edge off a sharp drink, and it also gives you the thing you probably miss most about a can.
Keep the base and the sparkling water separate until the glass. Mixed in a pitcher, it goes flat in 20 minutes.
Tips for tart lemonade people will drink
- Roll the lemons first. It breaks the membranes inside and gives you more juice.
- Zest before you squeeze. Add a strip of peel to the pitcher for oils and aroma. That’s flavor without sweetness.
- Add something fragrant. Mint, basil, or thin slices of cucumber make it taste complete.
- Sweeten the glass, not the pitcher. If different people want different levels, let them add it themselves.
- Reduce slowly. If you’re coming off a sugary lemonade, sweeten at first and use a little less each week.
Variations
- Pink lemonade: muddle 4 raspberries or strawberries in the glass.
- Lavender or rosemary: infuse a sprig in the pitcher for an hour.
- Ginger lemonade: add 2 tbsp fresh ginger juice to the base.
- Arnold Palmer style: half iced tea, half this. See our Arnold Palmer recipe for a lightly sweetened version.
- Mix and syrup shortcuts: sugar free lemonade packets and syrups exist and are handy for travel. They’re flavored products, so check the label.
How sugar free lemonade replaces your can of soda
Citrus sodas appeal for plain reasons: tart, cold and fizzy. A glass of this lemonade has all three. The CDC says one 12-ounce can of soda has more than 10 teaspoons (about 42 grams) of added sugar. This recipe has none unless you add some.
One honest note. If you use a zero-sugar sweetener, you’re keeping the taste of sweetness even though you’ve dropped the sugar. Some people are happy with that. Others are trying to reset how sweet things taste to them and prefer to use less over time. Neither is wrong, and it’s your call.
It has no caffeine, which makes it an easy afternoon or evening swap.
A quick sugar free lemonade for one glass
When you don’t want a pitcher, squeeze half a lemon into a tall glass, add ice and ¾ cup of sparkling water, and stir. Add a few drops of your sweetener and one thin lemon wheel. This version takes 30 seconds and is the one most likely to survive a busy afternoon.
If you’re comparing options, a shelf-stable lemonade drink mix or a lemonade syrup is faster still. Read the ingredient list on whichever you choose, compare how much you’d actually use per glass, and decide whether you like the taste better than fresh. Many people keep a packet in a bag for travel and use fresh lemons at home.
Another approach is to use less lemon altogether. If one cup of juice makes your base too sharp, try ¾ cup of juice with 3½ cups of water. The drink gets gentler, and you can raise the lemon again as your taste adjusts.

Questions
How do you make lemonade without sugar?
Mix fresh lemon juice with cold water, about 1 cup of juice to 3 cups of water, and leave out the sugar. It will be tart. Sweeten with a zero-sugar sweetener if you like, or top it with sparkling water so the fizz softens the sourness.
Is unsweetened lemonade too sour to drink?
Straight, it's sharp. Most people find it easier with sparkling water, ice, and mint, and by using 1 cup of juice to 4 cups of liquid rather than 3. Your taste for sweetness shifts if you cut sugar gradually, so start with a mild sweetener and use less each week.
What can I use to sweeten it?
Zero-sugar sweeteners come as drops, powders and packets, and they vary in strength, so follow each package and add a little at a time. Or skip them: a few raspberries, a slice of orange or a splash of unsweetened apple juice sweetens a glass naturally.
Can I use store-bought sugar free lemonade mix instead?
Yes, if you like it. Mixes and syrups are convenient, but they're flavored and sweetened powders. Check the label for what's in it. Fresh lemons, water and a sweetener you choose give you more control over the taste.
How long does it keep?
The lemon and water base keeps covered in the refrigerator for a few days. Add the sparkling water per glass so it stays fizzy. Fresh lemon juice tastes best in the first day or two.
