Mix up a keto bourbon bramble this weekend, or make a thoughtful gift for a loved one. It's so easy to bottle up and a wonderful substitute for simple syrup, or addition to more advanced cocktails. If you want to level up your low carb cocktail recipes, don't skip this simple and creative way to use your leftover fresh blackberries.
If you're looking for more low sugar liqueurs and syrups, be sure to check out our lavender simple syrup, sugar free grenadine syrup, or this homemade banana liqueur.
- Blackberries- Use nice and ripe fresh blackberries. Look for juicy and plump dark berries. It's almost like a deep purple/black color. You can use fresh or frozen berries here as well.
- Red wine - Use something medium bodied, and not sweet, since we will be adding sweetener later. Pick out something that you actually want to drink, since the wine does make up a large part of the flavor.
- Allulose sweetener - This is our favorite sugar free sweetener to use in place of sugar. It won't crystallize unlike other sugar free sweeteners, making it perfect for syrup like applications. It is slightly less sweet than regular sugar, so we use about 1 and ⅓ cups to every 1 cup of regular sugar. If you aren't concerned with sugar content, feel free to just use sugar.
- Liquor - We use vodka as a nice neutral liquor for this liqueur. Other spirits like gin especially will work. You do want to go with something neutral here, so you can mix up a variety of cocktails with it.
How to Make Sugar Free Blackberry Liqueur:
Place blackberries in a large bowl and cover with red wine. Mash very well with a potato masher or fork to release the blackberry juices. Cover and let sit for at least 48 hours. We like to leave it for 7 days. We put it in a mason jar so we can shake it every day or so. Store in a cool, dark place.
After you're done letting the wine infuse with the blackberries, strain once with a mesh sieve, then thru cheese cloth to get rid of any extra bits.
Pour strained liquid into a large sauce pan and add allulose. Simmer gently for about 10 minutes to dissolve it. Remove from heat and cool completely.
Stir in your liquor of choice. Either vodka or gin will work great.
That's it. Store indefinitely in a cool dark place. Add to your favorite cocktails, like this keto bourbon bramble!
Tips For The Keto Crème de Mûre:
- Sterilizing your storage bottle before putting the creme de mure inside will prolong the life significantly, even indefinitely if stored in a cool dark place! The best way to know if the liqueur is still good is to taste it, and watch out for any color changes. If you notice either of these changes, toss it. We highly doubt this stuff will last long enough for it to go bad. It's seriously delicious, and you will keep finding ways to use it!
- Fresh, ripe berries will produce the best flavor, but frozen can be used as well, though some of the ice might dilute the taste a bit. However, frozen ripe berries will always taste better than underripe fresh ones!
- Make a big batch of this for the holidays, and put it in small bottles to gift to friends and family. The will love it!
Crème de Mûre vs. Crème de Cassis:
Both liqueurs are berry macerations with red wine. They are also both sweetened , then have liquor added to them, this is true. The only difference is truly the berry used. Crème de mûre uses blackberries, while crème de cassis uses black currants.
Crème de mûre is darker in color and sweeter, while crème de cassis is lighter in color and more tart, like sour cherries. Both of these liqueurs can be hard to find, which is why we chose to make our our blackberry liqueur!
Black currants can also be very hard to find in the US. Sometimes you can find them in select grocers when they are in season, but usually you need to buy them dried online. Blackberry liqueur makes a wonderful substitute for crème de cassis if you are having trouble finding it.

Crème de Mûre Blackberry Liqueur (Sugar Free)
- 375 milliliters red wine (choose something medium bodied that you enjoy drinking)
- 504 grams blackberries, washed and stems removed (about 2 packages)
- 256 grams allulose sweetener (about 1 & ⅓ cups)
- 60 milliliters vodka or gin
- Place blackberries in a large bowl and cover with red wine. Mash very well with a potato masher or fork to release the blackberry juices. Cover and let sit for at least 48 hours. We like to leave it for 7 days. We put it in a mason jar so we can shake it every day or so. Store in a cool, dark place.
- After you're done letting the wine infuse with the blackberries, strain once with a mesh sieve, then thru cheese cloth to get rid of any extra bits.
- Pour liquid into a large sauce pan and add allulose. Simmer gently for about 10 minutes to dissolve it. Remove from heat and cool completely. Stir in your liquor of choice. Either vodka or gin will work great. That's it, enjoy!
- Store in clean bottles in a cool, dark place for up to 1 year.
- We're unable to give any information about the alcohol content in this liqueur. We image it's similar to any store bought version, but we can't make any guarantees.
- It's an estimate that there are about 20 servings in each batch after removing most of the actual blackberries after straining. Each serving is roughly 1.5 ounces. To get a more accurate picture of the serving size, you can weigh your final product to determine the amount of liquid leftover. Most servings are between 1 - 2 ounces, just depending on the person.
- Use a red wine that you enjoy drinking for this! Nothing too sweet though. The wine will take on a lot of flavor when it infuses and ferments with the blackberries.
- Allulose is the best option for your sugar free sweetener here, but it is slightly less sweet than sugar. We use 1 & ⅓ cups to equate to 1 cup of sugar. Just keep this in mind if you decide to use another sweetener. You can use anything you want instead, but just be aware that it might crystallize if it's not allulose.

I really like the sound of the is recipe using wine.
I often make blackberry cordial with only vodka and being that I don't really like vodka this recipe sounds better. The high alcohol content of the vodka makes the concoction safe I assume for melding in the pantry for a couple of months with added sugar. The recipes for the vodka cordial are similar to yours in that you put the vodka in the berries (with the sugar) and let it sit for a couple of months in a dark place shaking every week or so. I am wondering if I could do your recipe in this way with the wine and berries adding the sugar and the vodka after seven days to let the flavors meld till the holidays. Do you think that is a plausible route?
Thanks for you time.
Hey Kim! Thanks so much for reaching out about this and we hope you had a wonderful long weekend.
To be honest, we haven't tried it ourselves, but our assumption is that if that works for similar recipes, it should work for this one as well. 🙂
