    My first two runs were 1.9 - 1.8%. Then went up as high as 2.7% and has been 2.3% for 5 boils. I have 2,200 in one woods with 48% reds ad the other woods is 38% reds. My sugar content has not stayed at 2.3% for this long since I started 16 years ago. I guess it is just a gift from mother nature for the crazy weather.

    Our first run this year was 3% and then backed down to around 2.25%. Last year we struggled to even hit 2% - We are in Northern New York.

    Sugars are up to 2.0-2.1 percent but the soft maples were still around 1% when I checked on Sunday. The first couple runs on the soft maples had a metallic tasting sap, dumped it and the trees seem to be doing better now.

    I haven't checked my sugar content this year, but we will peak about 2.25 and often stay around 1.75%. We have a few reds. A lot of our trees are on ledge and we have few field side trees.

    Syracuse.com had an article today that predicted many changes in the maple industry, with pests and climate change reducing the length and quality of the season and a continued northward migration of maples. Someday, what is now taiga, will be the maple production zone. There's a tree in north-central Vermont that produces 10%. Attempts to clone it didn't succeed.

    Oh you guys are gonna hate me. Usually my ratio runs 33:1-37:1.

    But this year thanks, I think, to freakishly long cold season....out of 40 l sap, I got 2.25 l of light amber. Normally I would expect about 1 - 1.5l from thaty amount, I was just nearuping it down for storage purposes and noticed that it looked awfully close to syrup. A little more work and I had syrup, Brixed out perfectly

    That's like a ratio of approx 18:1. The trees are sugars - all 8 of them - with 5 being big yard maples rockin 3 spiles apiece and 3 lil bush sugars all on 1 spile each.

    Have no idea what my sugar content is but usually it's a solid 3%. I'm guessing it's currently running 6%? Someone do the math for me! Please!

    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

    Using the “Rule of 86,” you can figure that the number of gallons of sap you need to produce one gallon of syrup is equal to 86 gallons divided by the percent of sugar in the sap, so, 3% is 28.666 to 1, and 6% is 14.333 to 1.

    Well, this explains a bunch.... Unfortunately I had dumped 75 gallons last week to learn now that my hydrometer was reading a full point low.
