    You ought to see how good it is when you're boiling 35 Brix concentrate (Lapierre HyperBrix). Takes only about 2.5 gal concentrate to make a gallon of syrup. It just pours out of the evaporator in a steady solid stream.

    An old timer once asked me if maple syrup was an aphrodisiac.

    I said I didn't know, but if he could find us a grant I'd be happy to study it, but in the meantime, it wasn't a bad rumor to spread.

    I use the formula 88/sap sugar %. It comes very close. I boil my syrup to finish a 68.9% +/- .1. Using that formula works good for the heavier syrup, if you pack at 66%, I think the original rule of 86 will be pretty close. I find that my customers like the 68.9% better.
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.

    Thanks for the replies, I'm somewhat stunned there's not a known formula for this. I am thinking I need to go back to my high school chemistry to figure this out!
