Blackberry Basil Honey Syrup
Fifteen minutes, one saucepan, and a jar of this blackberry basil honey syrup in your fridge that makes everything — iced lattes, sparkling water, lemonade, iced tea — taste like you planned it that way.
One Jar. All Summer.
- The syrup takes 15 minutes and smells incredible the entire time. You have been warned.
- Honey instead of granulated sugar means a rounder, more floral sweetness that plays well with both the blackberry and the basil — and with whatever you pour it into.
- It works in coffee, iced tea, sparkling water, lemonade, and — quietly, in the optional add-in section — something with gin. We're not here to judge.
Where This Came From: This syrup started as an attempt to bottle the flavor profile of our Blackberry Sage Oolong Cold Brew Pods — dark berry, earthy herb, smooth base — and make it available in everything, not just the cold brew. Basil is the summer swap for sage (abundant, easy to find, same earthy-herb energy). If you have sage on hand instead, it works beautifully and takes the syrup closer to the pod that inspired it. Either way, the idea is the same: one herb, one berry, honey holding it all together.
The Tea That Started It
Blackberry Sage Oolong Cold Brew Pods are the reason this syrup exists. Drop a pod in cold water overnight and wake up to something that already tastes like someone put thought into your morning — bold blackberry, smooth oolong, a quiet earthy note from the sage. The syrup is what happened when we wanted that same flavor layered into everything else. You could use this syrup without ever trying the pod. But if you want to understand where the idea came from, that's the place to start.

What You'll Need
For the Blackberry Basil Honey Syrup:
- ½ cup water
- ½ cup honey
- ½ cup fresh basil leaves, roughly torn (or fresh sage — see Swaps)
- 1½ cups fresh or frozen blackberries
Makes approximately ¾ cup syrup — enough for 6–8 drinks.
For the Honey Cold Foam (optional, for lattes):
- 3 Tbsp heavy cream
- 2 Tbsp milk
- 1 tsp vanilla extract
- 1 Tbsp honey
How To Make the Syrup
- Combine everything. Add the water, honey, torn basil, and blackberries to a small saucepan. No particular order. They're all going to the same place.
- Simmer low and slow. Heat over medium, stirring occasionally, until the honey melts and the mixture reaches a gentle simmer. Drop to low and let it go for about 10 minutes — until the blackberries have completely surrendered their shape and the basil looks wilted and committed to the cause.
- Cool, then strain. Pull the pan off the heat and let it sit until it stops steaming. Pour through a fine mesh sieve into a jar, pressing the berries gently to extract every last drop. The strained blackberries and basil are genuinely good on yogurt — don't skip straight to the bin.
- Store it right. Sealed in the fridge, this syrup keeps for up to 1 week. It will not last that long.
Everything This Syrup Is Good In
☕ Iced Blackberry Basil Latte
The drink that started the whole project. Fill a tall glass two-thirds with ice. Add 2 Tbsp syrup, then 6 oz milk of choice. Pour 4 oz strong brewed coffee or espresso slowly over the top — it layers through the milk for about three seconds before someone stirs it. Worth the pause. Top with honey cold foam (froth heavy cream, milk, vanilla, and honey with a handheld frother for 20–25 seconds until creamy and pourable), garnish with fresh blackberries and a basil sprig.
Hot version: Add 2 Tbsp syrup to the bottom of a mug, pour hot brewed coffee over, stir, froth your milk of choice and pour over the top.
🍵 Blackberry Basil Iced Tea
This is where the syrup really earns its keep. Brew a strong black tea or oolong — or reach for our Blackberry Sage Oolong Cold Brew, which was the whole inspiration — and stir in 1–2 Tbsp of syrup over ice. The earthy herb note doubles down beautifully against an oolong base. Serve immediately and don't let anyone tell you this isn't a complete breakfast.
Start with 1 Tbsp and taste — the syrup is concentrated and honey-forward. You can always add more.
🫧 Blackberry Basil Sparkling Soda
The simplest use and honestly the most impressive one to hand someone at a backyard gathering. 1–2 Tbsp syrup over ice in a tall glass, top with sparkling water or club soda, squeeze of lime if you have one. Stir once. That's it. This is the one that makes people ask for the recipe before they've finished the glass.
Also excellent with tonic water for a slightly bitter, more complex finish.
🍋 Blackberry Basil Lemonade
Mix 2 Tbsp syrup with 8 oz fresh or store-bought lemonade over ice. The tartness of the lemon and the jammy sweetness of the blackberry do something genuinely interesting together, and the basil note keeps it from tipping into candy-sweet. Make a pitcher version by stirring ½ cup syrup into a full batch of lemonade. Serve it at something outside and watch people assume you put in a lot more effort than you did.
For a sparkling lemonade: mix with lemon juice and top with sparkling water instead.
🍸 The Optional Add-In (No Judgment)
This syrup slides into a gin and tonic, a vodka soda, or a prosecco pour with very little effort and very good results. 1–2 Tbsp in a glass, top with your spirit of choice and something sparkling. The earthy herb note in the syrup plays especially well against the botanicals in gin. We're a coffee and tea brand, so we're leading with that — but we're not going to pretend we haven't tested the gin version thoroughly.
Swaps & Permission Slips
- Want to use sage instead of basil? Do it. Fresh sage takes this syrup closer to the Blackberry Sage Oolong Cold Brew Pod that inspired it — earthier, slightly more savory, incredible in iced tea. Use the same quantity and the same technique.
- No fresh blackberries? Frozen work exactly as well — no need to thaw. Often more flavorful because they're picked at peak ripeness. Add an extra minute of simmer time.
- Prefer plain sugar over honey? Same quantity (½ cup) works fine. You'll get a cleaner, less floral sweetness. The honey version has more depth — it's the better choice if you have it, but sugar gets you there.
- No espresso machine for the latte? Brew double-strength coffee — two heaping scoops where you'd normally use one — let it cool, and use that. Works perfectly.
- Watching carbs or tracking macros? A brown sugar allulose blend or straight allulose at the same ratio makes a sugar-free version of this syrup with minimal glycemic impact and almost identical flavor. Same technique, same result.
One jar of blackberry basil honey syrup in the fridge and you'll find yourself adding it to things you hadn't planned on — Tuesday morning coffee, sparkling water at 3pm, something with gin at 7pm that you're calling a mocktail until proven otherwise. Make the batch. It goes fast.
Frequently Asked Questions
Can I use frozen blackberries to make blackberry basil honey syrup?
Yes — frozen blackberries work just as well as fresh and don't need to be thawed first. They're often more flavorful than out-of-season fresh berries because they're picked and frozen at peak ripeness. Just give the syrup an extra minute or two on the heat to make sure the berries fully soften and release their juice.
How long does homemade blackberry honey syrup last in the fridge?
Stored in a sealed jar or airtight container, this syrup keeps for up to 1 week refrigerated. Because it uses honey rather than granulated sugar, the shelf life is slightly shorter than a standard simple syrup — plan to use it within 7 days. Given how many things it's good in, that's rarely a problem.
Can I use sage instead of basil in this syrup?
Absolutely — sage and basil are in the same herb family and share that earthy, slightly peppery quality that makes this syrup interesting in drinks. Fresh sage takes the flavor profile in a slightly more savory direction, which is especially good in iced tea and sparkling water. Use the same quantity and the same technique as the basil version.
What does blackberry syrup taste like in coffee?
It tastes like coffee that has a very good reason to exist. Blackberry adds a jammy, tart-sweet layer that highlights the naturally fruity notes in most medium roasts, and the basil adds an earthy counterpoint that keeps it from reading as just sweet. It doesn't taste like fruit juice in coffee — it tastes like a deliberate flavor combination that someone actually thought through.
What's the difference between simple syrup and honey syrup?
Standard simple syrup uses equal parts granulated sugar and water for a clean, neutral sweetness. Honey syrup replaces the sugar with honey, which adds a floral, slightly complex sweetness that plays better with fruit and herb combinations like this one. It also has a slightly shorter fridge life — but more depth of flavor, which is the trade-off worth making here.
