    Default Question for maple syrup makers

    I am boiling sap for my second year as hobby. Question is how to know when sap is sour? I ask because there was an article on the news from a syrup maker talking about this being another short year due to the fact the temps wont fall below freezing at night spoiling the sap.
    Thanks in advance

    Hey David, it's pretty easy to tell when sap goes bad. Basically it is sugar water, so as soon as it's out of there tree it starts to break down from exposure to bacteria, yeasts, etc from the air and your containers. If it's cold out this action is greatly delayed. The warmer it gets the faster your sap spoils. Sap that smells a little off or is cloudy is definitely on the way to being bad, but it's not necessarily bad. Often it cooks down into great syrup. But once it smells like bread dough and starts to have a texture to it, it's probably too far gone.

    Usually you get 24 hours at least to get it heated up and pasteurized, often much more at the beginning of the season, and sometimes at the end of the season the sap is bad right off the tree. I hope that helps.

    Mostly I grow vegetables. I get to make firewood too, but not as much as I'd like. And if I'm really lucky, I get to make some maple syrup.

    Thanks, I think bad out of the tree is what he was referring to.

    We usually stop collecting sap when any of the following events occur: the buds start to form, when the sap in the pail becomes cloudy to the point of being yellowish and when the moths and other critters floating in the pail become prevalent on a daily basis. There are always various opinions, which is why it is as much art as science. In recent memory, we have had a number of season that were "interrupted", meaning they started and ran good but all of a sudden stopped (either weather changed to very cold both day and night or very warm for sap season both day and night). We have been fooled, thinking it was over and pulled our 300+ pails in only to discover the season re-started shortly after we cleaned up.
