Pin There's something almost magical about watching clear rum transform into liquid ruby over the course of two weeks. My cousin brought back a bottle of Jamaican rum from Kingston, and rather than drink it straightaway, I found myself standing in my kitchen wondering what would happen if I combined it with the blackcurrants I'd just picked up at the market. That impulse led to this liqueur, and now whenever I catch the scent of those berries steeping in alcohol, I'm transported back to that moment of curiosity.
I served this liqueur to friends last winter during a dinner party, pouring it into small glasses alongside dark chocolate mousse. The way their eyes lit up when they tasted it, that moment of recognition that this was something handmade and deliberately crafted, reminded me why I love creating things in my kitchen. One friend asked for the recipe that very evening, and I realized I'd accidentally created something people actually wanted to make themselves.
Ingredients
- Fresh blackcurrants: These little gems are tart and earthy, nothing like the sugary jam versions most people know, so seek them out at farmers markets or specialty shops during berry season.
- Jamaican dark rum: The molasses notes and slight smokiness in Jamaican rum are essential here; they don't disappear into the infusion but instead dance with the berry flavors.
- Granulated sugar: This dissolves slowly as the berries release their juices, creating a natural syrup that binds everything together.
- Vanilla bean: Split it lengthwise to expose those tiny black seeds, which add a subtle floral note that softens the alcohol's sharp edges.
- Cinnamon stick: A small piece goes a long way, warming the drink without overwhelming the delicate berry notes.
- Lemon zest: Just the yellow outer layer, never the bitter white pith, brightens the entire infusion with a whisper of citrus.
Instructions
- Prepare your vessel:
- Find a glass jar large enough to hold everything with room to shake it gently, then wash it thoroughly and let it dry completely. A clean jar is your foundation for clear, beautiful liqueur.
- Layer your ingredients:
- Pour the blackcurrants into the jar first, then scatter the sugar, vanilla, cinnamon, and lemon zest over top. The layering doesn't matter scientifically, but it does create a moment to pause and appreciate what you're about to do.
- Add the rum:
- Pour the Jamaican rum slowly over everything, watching the berries bob to the surface and the sugar begin to dissolve immediately at the bottom. Make sure every berry is submerged, as any that float above the liquid will oxidize and turn brown.
- Seal and shake:
- Cap the jar tightly and give it a gentle shake for about thirty seconds, feeling the sugar crystals tumble through the rum. This initial shake helps release some of the sugar's sweetness and signals the infusion process to begin.
- Infuse with patience:
- Store the sealed jar in a cool, dark cupboard or cabinet where you'll see it regularly but where it won't be jostled by daily use. Every two to three days, shake it gently again, and you'll notice the liquid gradually deepening from ruby to almost garnet by day ten.
- Taste and strain:
- After fourteen days, line a fine mesh strainer with cheesecloth and pour the entire contents through slowly, letting gravity do the work rather than pushing the fruit through. The liquid that drains first will be the clearest and most beautiful.
- Let it settle:
- Pour the strained liqueur into a clean bottle, seal it, and wait another two days on a shelf, undisturbed. This resting period lets any remaining tiny particles settle to the bottom, and it allows the flavors to stop shouting at each other and start harmonizing.
Pin There was a moment three days into the infusion when my partner walked past the jar and asked if something had gone wrong because it smelled so intensely of raw rum. I explained that this was exactly how it should smell, that in ten more days it would smell like a forest floor of berries and spices instead of pure alcohol. When we finally opened that bottle together two weeks later, and that aroma had completely transformed, I saw the understanding dawn on their face that this was real fermentation and infusion at work.
Extending Your Infusion
If you have patience and curiosity, you can push the infusion to twenty-one or even twenty-eight days, and the liqueur becomes noticeably deeper in color and more complex in flavor. I've found that somewhere between eighteen and twenty-two days is the sweet spot where you get maximum berry character without the tannins becoming too strong. The longer you wait, the less it tastes like a novelty drink and the more it tastes like something genuinely sophisticated.
Adjusting Sweetness
After you strain and before you seal your final bottle, taste a small sample and decide if you want it sweeter or slightly less so. If it's too dry for your preference, you can dissolve a bit more sugar in a small amount of hot water, cool it, and stir it in gradually until you reach the balance you love. Some people prefer it almost like a cordial, thick and sweet, while others want just enough sugar to round the edges of the alcohol and fruit without tipping into dessert territory.
Serving Suggestions and Storage
Serve this liqueur straight from the freezer in small glasses, over premium vanilla ice cream, or mixed into cocktails that need something with real depth and character. Kept in a cool dark cabinet or cupboard, it will stay vibrant and delicious for up to a year, though honestly I've never had a bottle last that long. Here are three essential thoughts as you finish your creation:
- Gift bottles in small glass jars with handwritten labels, because homemade liqueur is the kind of present people remember and actually use.
- Make a double batch if you have the blackcurrants, because this is one of those things people will ask you to make for them once they've tasted it.
- Don't worry about imperfection in how it looks or tastes, because the best liqueurs are the ones made with genuine intention rather than commercial precision.
Pin Making this liqueur taught me that sometimes the best kitchen creations aren't rushed or complicated, but rather things you simply get right by showing up and shaking a jar every few days. This drink carries that lesson in every sip.

The full infusion process takes 14 days in a cool, dark place, plus an additional 2 days of resting after straining for optimal flavor development.
