    The consumers don't care about the frogs or the pussy willows. If you're making good tasting syrup, keep going. If not, stop.

    Normal progression of thinking when poor syrup is made:

    - yuck, that's bad
    - might be a little better today
    - it's not terrible
    - seems OK
    - it'll be fine
    - we can still sell it

    Turned out the sap we collected over the weekend was ropey and unable to be completely processed. One of the drawbacks of measuring every drop of sap (for research) is that we are unable to fully...

    Foaming in late season can be high. Foaming with a clean pan can be high (no residual defoamer spread throughout pan). You got both at the same time.
