Rule of 87 or 86
We just were thinking about the rule of 86 or 87 depending on if you are in VT or not. To figure how much sap makes a gallon of syrup you divide 87 by your sugar content. Simple, 2%sap 86/2 it takes 43 gallons of sap to make a gallon of syrup. Well we have 100 gallons of 12% sap and wanted to know how much syrup we will have when we are done. Rule of 86 is 86/12 =7.25 100 gallons 100/7.25 = 13.79 gallons of syrup. Here is where I get confused. If I have syrup at 66% sugar then the rule of 86 would say it takes 1.3 gallons of syrup to make a gallon of syrup. This makes no sense. Can some one clear this up? Thanks
