Well been busy here cause I now can't use sugar shack stove, creosote buildup cause I was burning green wood from the pallets, even though I cleaned out stove and chimney as best as I could between burns, so I was risking both syrup tasting of creosote and a shack fire. Luckily the cold weather froze up storage jugs and pails hard enough that was able to get sap concentrate, though I felt guilty chucking away ice. But now that I have to revert to boiling indoors see no other way to do it.
