Cold brew is already smooth. Add lychee and rose, and it becomes something you’d pay eight dollars for at a specialty café.
The idea came from a can of lychees sitting in my pantry. Instead of eating the fruit, I reduced the syrup with a handful of dried rose petals. The result was a floral concentrate that pairs surprisingly well with coffee.
The key is balance. Too much rose and it tastes like soap. Too much lychee and the coffee disappears. The ratios here are tested to keep all three flavors present.
You’ll need about 12 hours of hands-off steeping, so plan ahead — the same overnight cold brew approach applies here. Active work is under 15 minutes total.
Why You’ll Love This Recipe
- Ready with only 15 minutes of hands-on prep time
- Homemade lychee syrup costs less than café versions
- Low-acid cold brew keeps floral notes clean and bright
- Syrup keeps for two weeks, so batching is easy
Ingredient Notes
- coarse-ground coffee: Use a medium or medium-dark roast ground to coarse filter grind. A fine grind clouds the brew and over-extracts, making it bitter.
- canned lychee syrup: The packing syrup from a 20 oz can of lychees works perfectly here. If you use fresh lychees, simmer peeled fruit with equal parts water and sugar instead.
- dried rose petals: Use culinary-grade food-safe dried rose petals, not potpourri. Rose water can sub in a pinch – start with 1 tsp and taste before adding more.
- filtered water: Tap water with strong chlorine flavor will come through in a 12-hour steep. Filtered or bottled water gives a cleaner result.
- granulated sugar: Added to the syrup to boost body. You can use honey instead for a slightly floral undertone that complements the rose.
Lychee Rose Cold Brew Recipe
Ingredients
Method
- Add 85 g of coarse-ground coffee to a 32 oz glass jar or pitcher.
- Pour 950 ml of cold filtered water over the grounds and stir gently until all the coffee is wet.
- Cover the jar with a lid or plastic wrap and place it in the fridge. Steep for 12 to 14 hours - no longer or it will turn bitter.
- Set a fine-mesh sieve over a clean pitcher and line it with a paper coffee filter. Pour the cold brew through slowly. Discard the grounds. Set the strained concentrate aside.
- Rinse 3 g of dried rose petals briefly under cold water to remove any dust. Drain and set aside.
- Combine 240 ml of lychee packing syrup and 36 g of sugar in a small saucepan over medium-low heat.
- Stir until the sugar dissolves, about 2 minutes. Add the rinsed rose petals.
- Reduce heat to low and simmer for 8 minutes, stirring once or twice, until the syrup smells floral and is slightly thickened. Do not let it boil hard.
- Remove from heat and strain the syrup through a fine-mesh sieve into a clean glass bottle. Discard the rose petals. Let the syrup cool to room temperature, then refrigerate until ready to use.
- Fill a tall glass with ice cubes.
- Pour 150 ml of cold brew concentrate over the ice, followed by 60 ml of cold water or oat milk to dilute.
- Add 2 tablespoons of lychee rose syrup and stir gently until combined.
- Taste and add an extra teaspoon of syrup if you want it a little sweeter. Garnish with a fresh or canned lychee on the rim and serve immediately.
Notes
Tips for Success
- Steep the cold brew in the fridge, not at room temperature, to prevent any sour fermented notes after 12 hours.
- Simmer the lychee rose syrup on low heat only – a hard boil drives off the rose aroma in under two minutes.
- Strain cold brew through a paper coffee filter set inside a fine-mesh sieve for a completely clear, sediment-free result.
- Taste the syrup before adding it to coffee — it should smell floral but not perfumed, the way a well-made homemade coffee syrup balances aroma without overwhelming the cup, so adjust rose petals by 1 tsp at a time.
- Pour cold brew over ice before adding syrup so the ice dilutes the coffee first, then stir syrup in last to preserve its fragrance.
Variations
- Add 2 tbsp coconut milk per glass for a creamy lychee rose cold brew latte with a tropical note.
- Swap dried rose petals for dried hibiscus to make a tart lychee hibiscus cold brew with deep red color.
- Use the syrup with sparkling water instead of cold brew for a caffeine-free lychee rose soda spritzer.
Storage and Reheating
Cold brew concentrate keeps in a sealed glass jar in the fridge for up to 14 days. Keep it undiluted until serving so it stays fresh longer.
The lychee rose syrup lasts up to 2 weeks refrigerated in a clean glass bottle. Shake it before using since the rose petals settle.
Don’t freeze the cold brew – it separates on thawing and loses the clean mouthfeel. The syrup can be frozen in ice cube trays for up to 2 months if you make a large batch.
Serving Suggestions
Serve over a full glass of ice with a 1:1 ratio of cold brew to water, then add 2 tbsp of lychee rose syrup. A fresh lychee fruit on a cocktail pick and one dried rose petal on top makes it look like something from a proper café.
For a brunch spread, set out the cold brew concentrate, syrup, and a few milk options so guests can build their own glass. Oat milk and the lychee rose syrup are a strong combination.
It also works as a mocktail base — and if you want to explore the full range of coffee cocktails to impress guests, skip the coffee here, use cold brew-steeped black tea instead, and top with soda water for a non-caffeinated floral drink.
FAQ
Why does my lychee rose cold brew taste soapy?
Soapy flavor almost always means too many rose petals or over-steeping the syrup. Pull the petals after 8 to 10 minutes of simmering and start with 1 tablespoon of dried petals instead of more.
Can I use rose water instead of dried rose petals in the lychee syrup?
Yes, but use it sparingly – start with 1 teaspoon and taste before adding more. Rose water is concentrated and tips into soapy flavor faster than whole dried petals.
Can I make the lychee rose syrup weeks in advance and freeze it?
Freeze it in an ice cube tray for up to 2 months. Pop out a cube or two per glass and let it melt into the cold brew rather than storing open bottles in the fridge indefinitely.
What food goes well with a lychee rose cold brew?
Light, not-too-sweet foods work best – think almond croissants, jasmine rice pudding, or fresh fruit with Greek yogurt. Heavy savory food competes with the floral notes.
Is lychee rose cold brew lower in caffeine than hot coffee?
Cold brew is actually higher in caffeine per ounce than drip coffee because of the high coffee-to-water ratio during steeping. Diluting it 1:1 with water or milk brings it closer to a standard cup.
What is the difference between lychee rose cold brew and a lychee cold brew latte?
Cold brew uses only the coffee concentrate and floral syrup, keeping it black and low-calorie. A latte version adds steamed or frothed milk, making it creamier and roughly doubling the calories per glass.
