hey guys .so I boiled 2017 gallons of sap. made 28.5 gallons. what is my sugar content of raw sap. any one have a formula? I know it is 70-1,so it must be around
1%-1.2%.

You were just over 1.2% sugar. 87.1 divided by 1.2=72.5. Gallons.

so where does the 87.1 come from? good guess, low sugar content.

87.1 is the official number to go by in the State of Vermont. At least that's what I have been told. That is also whats on the Cornell sap selling spread sheet.

i tried to up load the pdf, but too large.
here's a link to a thread i started on sbi that has the pdf that spud was referring to.

The revised formula according to the article in the Maple Digest written by Dr. Perkins is S = 88.2/X-0.32. This is for 66.9 brix syrup. The formula using 87.1 is for 66 brix syrup. X is the sap sugar content and S is the volume of sap to make a gallon of syrup. So it took 70.77 gallons of sap to make a gallon of syrup. So that means your average sugar content was 1.24 brix assuming you finished your syrup to precisely 66.9 brix with no waste.

thanks guys, I understand now

I always use the old rule of 86. Been around forever. 2017/28.5 = 86/x. where x is % sugar. Solve for x. 2017x = 28.5 times 86. Therefore 2451/2017 = x. Divide to find x. x = 1.22 % sugar.

The old Rule Of 86 should not be used (with 86 anyway) since it is no longer accurate. The "86" part came way back when correct syrup density was 65%. The Jones Rule is still good but needs the current numbers plugged into it.
