Sap from maple trees typically starts to go bad when the temperature rises above 25 degrees Celsius (77 degrees Fahrenheit). To ensure your sap stays fresh for the longest possible time, store it in a cool, dry place. Refrigeration is also a good option, as it can extend the life of sap by several weeks.

What temp does sap spoil?

Sap spoils quickly when stored at temperatures above 40°F (4°C). At temperatures above this, sap will spoil within a few days. To prevent spoilage, store sap at temperatures below 40°F (4°C). It’s also important to keep sap away from direct sunlight and extreme temperatures to avoid spoilage.

How long does sap take to spoil?

Sap typically spoils after about a week when left at room temperature. If you store the sap in a refrigerator, it can last for up to a month. However, if you plan on using the sap, it is best to use it within a few days of harvesting.
