|This is the big kettle used for gathering sap. Although the top of the Harmon (made in Pennsylvania, USA!) Pellet Stove does not get hot enough to boil the sap, it does heat it up nicely. Those skulls are from some of the deer I've shot. The picture of the dog is a painting I did.|
I use one of these reusuable coffee filters to strain the sap that is poured from the jugs into the collection kettle. It strains out flies, bugs, ants, and moths all of which like to drink sap. It doens't work for filtering the minerals from the syrup, however. For that you'd use wool.
