This lovely (and easy!) to make creme de mure is liqueur made with fresh blackberries is the perfect gift for the holidays. It’s so easy to bottle up, and is a wonderful substitute for simple syrup. If you want to elevate your keto cocktail recipes, don’t skip this simple and creative way to use some delicious summer fruit.
We include lots of process pictures in the body of the text, as well as ideas for substitutions and more. Feel free to skip to the recipe card if you’d like to get right into it. This post is also available as a Google Web Story!
- 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 1/3 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 & 1/3 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 & 1/3 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.
