I didn't collect a thing yesterday, it was flowing....slowly.... I think, or it was rain I saw dripping in the buckets. How do you know if it is rain water or sap? Other than using my refractometer. 1 of my water jugs on the forest floor had a few liters in it, but it had a yellowish tinge to it, don't think I will keep that, unless I am told otherwise by you wonderful people. My last 2 batches I have boiled down have ended up really really dark, can't even see through it even when held up to the light, but taste's wonderful, I prefer the dark anyhow.
