Nature’s most skilled and experienced syrup makers are the bees. They’ve been making syrup out of plant nectar for millions of years. The process they use is the same one we employ for making syrup out of tree sap or cane juice: reduction. They start with a thin 80-20 water-to-sugar solution that they extract from flowers, then slowly reduce it until it has a moisture content right around 18%. At that point they deposit the syrup in a cell in the honey comb, cap it off with wax and await the winter (or the beekeeper).
