How long to hold sap?

This is my family's second year doing Maple syrup. How long can we hold the sap before it is no longer good to boil?

Frozen - for a very long time.
Refrigerator temps - for a few days or so like milk.
Watch it and if you see it starting to get cloudy get at boiling.

This time of the season around here, not long. You should be processing it the same day you collect. The trees are warming up and bacteria is forming. I would say 2 days tops. You will smell it. If it has an oder, dump it. If it is spoiled, you will make off flavor syrup. Watch your trees to see if they are budding, if so stop. Red maples will bud first, than sugar maples.
