Blackberry Liqueur
Crème de mûre, made from blackberries, and routinely confused with crème de cassis, which is blackcurrant. They are different fruit with different acidity, and a Bramble made with the wrong one is a different drink.

Tasting Notes
Ripe blackberry aroma with jammy fruit notes and gentle acidity. Smooth, rounded palate with a deep purple hue and a clean finish when well made.
Recommended Brands
Budget Choice
Giffard Crème de Mûre: the widely stocked one, and plenty for a Bramble
Premium Choice
Briottet Crème de Mûre: more fruit and less sugar, which shows when it is poured over the top
Storage & Handling
Store upright in a cool, dark place. Once opened, reseal tightly after use. Refrigeration is optional but helps preserve freshness over extended periods.
Shelf Life
Unopened: Indefinite. Opened: Best within 18–24 months for optimal flavour
Usage
Poured at 10ml to 15ml, and in a Bramble drizzled over the finished drink rather than shaken into it. It sweetens and colours at once, so the syrup in a build comes down when it goes in.
Mûre, Not Cassis
Crème de mûre is blackberry and crème de cassis is blackcurrant, and the two get swapped constantly because both are dark, sweet and French. They are not interchangeable. Blackcurrant is sharper, more tannic and more aggressively perfumed, and it will dominate a drink built for the rounder, jammier blackberry. A Kir made with mûre is underpowered and a Bramble made with cassis is strident. As with any crème, the word describes a minimum sugar level rather than any dairy content.
The Bramble
The Bramble is gin, lemon and sugar shaken and poured over crushed ice, with the blackberry liqueur drizzled over the top afterwards rather than mixed in. That sequence is the entire point. Drizzled last, it bleeds down through the ice in streaks, so the first sips are sharp and gin-led and the last are sweet and fruited, and the drink changes as it is drunk. Shake it in instead and you get a uniformly sweet purple sour, which is a perfectly nice drink and not a Bramble.
Real Fruit or Flavouring
The category splits sharply on price and the ingredients list tells you which half a bottle is in. A liqueur made with actual blackberries carries a slight tannic grip and a colour that leans towards purple-brown. The cheap end is sugar, alcohol and berry flavouring, and it reads as sweet with a generic dark-fruit note and a colour closer to ink. In a Bramble, where the liqueur sits on top undiluted and is tasted almost neat, that difference is impossible to hide.
Keeping It
Sugar and alcohol together preserve it, so an unopened bottle is stable for years and an opened one for a long time. What it does lose is freshness of fruit rather than safety: the bright top note fades first and the sweetness stays, so an old bottle reads flatter and sweeter than a new one. Keep it sealed and out of the light. Refrigeration is not required and does no harm, and it slows the fading in a bottle that will take a year to finish.
Pro Tip
If a drink turns purple but tastes flat, the liqueur is doing the work. Add acid, not more fruit.
Top Tips
- Check whether it is mûre or cassis. Blackberry and blackcurrant are not the same fruit.
- Drizzle it, do not shake it, in a Bramble. The bleed through the ice is the drink’s whole appearance.
- Read the ingredients for fruit. The cheap end is flavouring and sugar, and it tastes of neither.
Possible Substitutions
- Crème de cassis (darker, more intense)
Production Method
Produced by macerating blackberries in neutral spirit, then sweetening and blending to achieve balance and colour. Premium versions rely on high fruit content rather than artificial flavouring.
History & Context
Blackberry liqueur has long been part of European fruit liqueur traditions. Its use in cocktails increased during the mid-20th century alongside tropical and fruit-forward drinks, where colour and sweetness were as important as flavour.
Common Questions
Blackberry liqueur versus crème de cassis?
Different fruit. Mûre is blackberry, rounder and jammier; cassis is blackcurrant, sharper and more tannic. They get confused because both are dark, sweet and French, but a Bramble made with cassis is strident and a Kir made with mûre is underpowered.
How do you build a Bramble?
Shake gin, lemon and sugar, pour over crushed ice, then drizzle the blackberry liqueur over the top rather than mixing it in. The bleed through the ice is the point: the drink starts sharp and gin-led and finishes sweet and fruited.
What else does it do?
It works anywhere dark fruit suits a sour, so a blackberry gin sour or a whisky sour with a drizzle both hold up. It also lengthens with sparkling wine as a Kir variation, though cassis is the traditional choice there and reads sharper.
Does it need refrigerating?
No. Sugar and alcohol preserve it, so an opened bottle keeps for a long time at room temperature. What fades is the bright fruit note rather than the safety, so refrigeration is worth it only for a bottle that will take a year to finish.
