  • 1 tbsp prepared sugar free cranberry sauce (we omitted the cinnamon and vanilla extract for this application)
  • 2 ounces apple cinnamon infused whiskey (could sub for regular whiskey)
  • 1 tbsp* Spiced simple syrup, to taste (we recommend using about 1 tablespoon to start and then adjust from there, see notes)
  • 1 dash Angostura bitters
  • Garnish with orange peel, cranberries, rosemary sprig (your choice)


  • Fill two rocks glasses with ice. Spoon in the low carb cranberry sauce to taste, we used about a tablespoon.
  • Add in some spiced simple syrup to taste. Add a small amount first, then adjust once you put the cocktail together to make sure that the sweetness level is to your liking.
  • Now, simply add in your apple cinnamon infused whiskey, a dash of angostura bitters and then stir! Taste, then adjust sweeteners if you want.
  • Now, simply garnish with cranberries, and orange peel and a rosemary sprig if you want.


This drink is made with our keto cranberry sauce. The instructions to infuse your whiskey as well as make spiced sugar free simple syrup are below. Please note, you can make any changes you see fit but it will likely affect the macros. 
To make the infused whiskey: A few days before making the bourbon sangria, we recommend making your Apple Cinnamon infused whiskey. You can simply add 4 cinnamon sticks and 1 cut up apple to a mason jar and cover it with 16 oz whiskey of choice, and let it infuse for at least 3-4 days. Strain before use and discard the fruit and cinnamon sticks.
To make the infused simple syrup: When it’s time to make the sangria, start with your spiced simple syrup. It should cool down a bit before handling it. In a sauce pan, add whole spices to toast until fragrant. We used: 4 cinnamon sticks, 5 whole cardamom pods, 6 cloves, and 3 star anise. You could add as much or as little as you want of each.
Add 24 oz water and let the spices and the water come to a rolling boil. Allow the spices and the water to boil together for 15 minutes. The reason we do this is to get a very strong spice flavor infused into the water.
After the water turns a nice golden brown, it’s ready. Simply remove and discard the spices, and then add 1 cup of allulose sweetener until it dissolves. You can stir with a spoon to help it along. You do want the water to be quite hot while adding the sweetener. Set aside to cool. Store in an airtight container in the fridge for up to 3 months.  
We don't include carbs from the infused whiskey, as we aren't food scientists and we aren't sure how we would do that. We do feel that the carbs are negligible anyway.
