Just add apple cider vinegar!
Ingredients: Garden fresh onion, garlic, cayenne, horseradish, rosemary, thyme, oregano, sage, organically sourced cinnamon sticks, ginger, oranges and lemons. 
Top the jar with vinegar, let infuse for 4 weeks shaking occasionally. Strain.
If you wish for a sweeter fire cider then now is the time to mix equal amounts of honey to vinegar. Shake well. This is a shelf stable product.
