My buds are slowly opening on the silvers. I have been cooking the sap from them and not having a problem with taste. I'm guessing because they are not fully popped, is the reason the sap is still ok.
My biggest run so far is only 54 gallons on 49 taps. Haven't reached 200 gallons sap yet for the season.
I may keep cooking. One tree is giving me really woody smelling sap so we dump that one.
I have a couple sugars I can continue with.
