If your vinegar contains only dried herbs and spices, they can be left in the jar for the duration of the vinegar use
Fresh ingredients need to be strained out after one month
Vinegars made for cosmetic uses can be concocted with fresh or dried herbs but be sure to strain the herbs out of any vinegar that will be used topically
Place a funnel into the opening of a clean, sterilized jar and lay cotton muslin over the top of the funnel
Pour the contents of the jar with the infusing vinegar through the muslin, being careful not to let the contents fall out of the side of the muslin
Let all the vinegar drain through the muslin cloth and funnel into the clean jar
If your vinegar is made with fresh ingredients, don’t squeeze what is in the muslin, or water will squeeze out of the fresh ingredients giving you a cloudy vinegar with a shorter shelf life. Just let liquid drip on its own
Discard the strained-out ingredients into the compost. The liquid left behind is your herbal vinegar
