Peach Rosemary Fizz Mocktail: A Bubbly, Herbal Summer Sipper

It’s the kind of drink that feels dressed up without any alcohol in sight, perfect for anyone at the party who’s skipping the bar cart. Grab a shaker and a few sprigs of rosemary, because this one comes together in minutes.

Why This Peach Rosemary Fizz Belongs on Your Party Menu

This mocktail solves a real problem: most non-alcoholic drinks lean either candy-sweet or flat-out boring. The rosemary simple syrup here does the heavy lifting, adding an herbal, almost savory edge that keeps the peach from tasting like juice box. It reads as sophisticated the second it hits the table.

It’s also endlessly flexible for a crowd. Batch the rosemary syrup and peach puree ahead of time, then let guests top their own glass with soda water right before serving. Nobody’s stuck bartending all night, and everyone gets a fresh, fizzy pour.

Because it’s alcohol-free, it works for baby showers, brunches, backyard barbecues, or just a Tuesday when you want something that feels like a treat. Expect people to ask what’s in it.

Everything You’ll Need

The ingredient list is refreshingly short, and there’s plenty of room to customize it with what you already have on hand.

• 1 cup fresh peaches, peeled and sliced (or ¾ cup peach nectar)
• 2 fresh rosemary sprigs, plus more for garnish
• ¼ cup granulated sugar
• ¼ cup water
• 2 tablespoons fresh lemon juice
• 1 cup club soda or sparkling water
• Ice
• Peach slices, for garnish

Bottle Picks & Easy Swaps

Skip the bottle shop entirely here — this recipe is built to be alcohol-free from the ground up. For the club soda, a plain sparkling water works just as well if that’s what’s in your fridge; just make sure it’s unflavored so the peach and rosemary stay front and center.

No fresh peaches on hand? Frozen peach slices, thawed, work beautifully in the puree, and peach nectar is a fine shortcut if you’re short on time. If you want to turn this into a cocktail for the adults in the room, a splash of peach schnapps or a light gin pairs nicely with the rosemary syrup.

Bar Tools You’ll Want

A few basics make this drink come together fast and look sharp in the glass.

• A cocktail shaker, for blending the peach puree and syrup with ice — this 6-Piece Cocktail Shaker Set comes with the shaker, strainer, muddler, jigger, mixing spoon, and pour spout, so you’ve got everything in one kit.
• A jigger for measuring the syrup and lemon juice accurately, so the balance stays right every time — this stainless steel jigger makes quick work of it.
• A muddler, handy if you want to mash fresh peach directly in the shaker instead of pureeing it separately — this bar muddler gets the job done.

Let’s Mix It Up

Once everything is prepped, this cocktail comes together in just a few minutes.

1. Make the rosemary syrup: Combine the sugar, water, and rosemary sprigs in a small saucepan. Simmer over low heat for 5 minutes, stirring until the sugar dissolves. Remove from heat, let the rosemary steep for 10 minutes, then strain out the sprigs and let the syrup cool.
2. Puree the peaches: If using fresh peaches, blend them until smooth. Skip this step if you’re using peach nectar.
3. Shake it up: Add the peach puree, 2 tablespoons of the rosemary syrup, and the lemon juice to a shaker with ice. Shake for 15 seconds until well chilled.
4. Strain and pour: Strain the mixture into a glass filled with fresh ice.
5. Top with soda: Slowly pour the club soda over the top to keep the fizz lively.
6. Garnish: Add a rosemary sprig and a thin peach slice to the glass and serve right away.

Host’s Tips for the Best Peach Rosemary Fizz

• Use large, clear ice cubes if you can — they melt slower and keep the drink from getting watered down.
• Make the rosemary syrup up to a week ahead and store it in the fridge, so all you have to do on party day is shake and pour.
• Pour the soda water slowly and along the side of the glass to keep as much fizz as possible.
• Slap the rosemary garnish sprig between your palms once before adding it to the glass — it releases the oils and makes the aroma hit you before you even take a sip.
• Taste your peaches before you puree. If they’re on the tart side, add an extra half tablespoon of rosemary syrup to balance things out.

Easy Ways to Make It Your Own

One of the best things about this recipe is how easy it is to tweak for different tastes and occasions.

For a boozy version, add 1.5 ounces of white rum or peach schnapps to the shaker along with the puree. Want it sweeter? Stir in an extra half tablespoon of rosemary syrup before topping with soda. If you’d rather go lighter, cut the syrup in half and add a squeeze of extra lemon for a crisper finish. Swap the rosemary for thyme or basil if you want a different herbal note, or add a few muddled raspberries for a fruitier twist.

Perfect Occasions & What to Serve Alongside

This drink shines at summer brunches, bridal or baby showers, and backyard dinners where you want something that photographs as well as it tastes. It’s also a natural fit for a mocktail bar at a wedding or a holiday gathering where not everyone is drinking.

Pair it with light bites like a goat cheese and prosciutto crostini, a burrata salad with fresh basil, or grilled peaches with honey for a dessert that echoes the drink itself.

Make-Ahead & Serving Notes

The rosemary syrup and peach puree can both be made up to 3-5 days ahead and stored separately in airtight containers in the fridge. Combine them with the lemon juice in a pitcher when you’re ready to serve, and add the soda water fresh to each glass right before handing it over, so the fizz doesn’t fall flat. For a crowd, multiply the syrup and puree by however many servings you need, but always top individual glasses with soda rather than mixing it into the full batch.

FAQs

Still have a question? Here are a few of the most common ones readers ask before making this peach rosemary fizz mocktail.

Can I use dried rosemary instead of fresh?

Fresh rosemary gives a cleaner, brighter flavor, but dried will work in a pinch. Use about a teaspoon of dried rosemary in place of each sprig when making the syrup, and strain well since dried herbs can leave gritty bits behind.

Is this drink very sweet?

Not overly. The rosemary syrup is balanced by lemon juice, so the final drink lands more bright and herbal than sugary. You can always add a touch more syrup if you prefer it sweeter.

Can I make this without a blender?

Yes. Peach nectar or a store-bought peach puree works well and skips the blending step entirely. If your peaches are very ripe, you can also mash them by hand with a muddler.

How far ahead can I prep this for a party?

The rosemary syrup keeps for up to two weeks in the fridge, and the peach puree holds for about 3-5 days. Just wait to add the soda water until you’re pouring individual glasses so the drink stays fizzy.

What’s the best way to turn this into a cocktail?

Add 1.5 ounces of white rum, vodka, or peach schnapps to the shaker along with the puree and syrup. The rosemary and peach flavors hold up well against spirits without getting lost.
