    Default Finishing Syrup By Simmering Rather Than Full Boil.

    I have been experimenting with the final stages of boiling by reducing the heat on my finishing pan to a very low rolling simmer. Once I have reduced the sap from
    (for example) 50 gal. to 5 gal. (90% reduction) I transfer to a pan that I boil at a much lower heat. It takes a bit longer and more fuel but the end result is equally superb clean clear syrup and NO NITER!!! I brix out at 67 to 68. Also, easier clean up on the pan and very little remainder in the filter. I have done this with the Black Walnut and the Maple I have processed with excellent results for both. I have been sugaring for about 35 years and have been doing this for the last 7 years with no untoward effects. Has anyone else tried this or can anyone tell me if there is a good reason (outside of fuel savings) why I should not be doing this?
    Thanks so much and best of all,
    Johnny (Jeeves)

    We sort of did something similar back in the 70's and early 80's but in reverse. Back then we only had between 7 and 9 taps, 3 on sugar maples, the rest on box elders (ash leaf maples). We simmered everything on the wood stove in the living room, with 2 windows partially open for a cross breeze. Then as it neared syrup density, we boiled it on the gas stove in the kitchen to finish it. It worked fine. I see no reason it wouldn't be good.
    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.

    Interesting that there would be no niter! Humm. Better see What Dr. Perkins has to comment on that one? Good job!
    Keep simmering I guess??

    I've done this too, many times over the last 2-3yrs, finishing syrup at a low simmer on my cast iron woodstove. Problem is, the syrup tends to be too dense and so have to add fresh sap or distilled water to get it right.
    Been tapping since 2008.
    2018 - 17 taps/7 trees...819l sap, approx 28l syrup
    2019 - 18 taps/8 trees...585l sap, 28l syrup...21:1 ratio
    2020 - 18 taps/8 trees...890.04l sap...gave away about 170l, 30l snafu'd....23l total for me from approx 690l
    2021 - 18 taps/8 trees...395l sap, 12 l syrup
    2022 - 18 taps/8 trees....7 sugars 1 red due to #2 having surgery so had the season off....582l sap, 18.5l syrup
    2023 - 18 taps/8 trees...all sugars again. 807l sap, so far approx 14l syrup
