The basic idea here is to emulate the nectar flowers produce. The main sugar in Flower nectar is Sucrose, the same as the granulated sugar in the paper bag you buy at the local Grocery store. Flowers will produce a tiny dribble of anywhere from 25 to 70% sucrose. Honeybees will then process that nectar to produce the Honey, which is primarily Fructose and Glucose.
2:1 syrup, or two parts granulated sugar to one part water is at 66% sugar. This is closest to honey, before it starts getting super saturated in solution. You would need to dissolve any crystals of sugar, the molecules will then just start using any solids as "seed," and you'll end up with a bunch of rock candy.
1:1 syrup, or one part sugar to one part water is at 50% sugar. This is closer to the actual nectar Bees are gathering. A pint is around a pound, a liter is about a kilogram, of both granulated sugar or water.
I make 2:1 syrup by dissolving 2 parts sugar, by stirring with a long wooden spoon, in 1 part hard boiling water until the syrup turns clear. I then put the lid on, set the pot in a bath of cold water until it's cool enough to funnel into jugs, and dilute it with water when I need it. If I'm feeding for winter, I already have it done the way I need.
