How To Filter Maple Sap and Syrup.
From tree to table, sap is filtered three times. Each step is simple but necessary as it removes sugar sand from syrup, creating a tasty and clearer end product.
Step One: Daily Sap Filter
Each day pour collected sap through the light filter to remove debris. Keep filtered sap chilled until ready to boil.
Step Two: Mid-Boil Filter
Once sap reaches the 216°F range, run it through the lighter prefilter to remove the majority of sugar sand. Typically, sugarmakers suspend this filter over the finishing pot and pour it directly through. That pot can then be put directly on the stove for the final boil. Remember: handle with care, sap is hot!!
Step Three: Final Filter
For this last step, suspend the lightweight prefilter inside the heavier filter and place over a clean pot. When syrup reaches its finished temperature, pour through this two-stage filter into waiting bottles or jars. Syrup will drain through quickly but sugar sand will be trapped in the filters.
