RFR, cover your trees' ears so they don't hear...my trees are finally drying!! Still not budding but so relieved. And this morning when rinsing out a water jug, noticed a distinct sour smell, about 1 cup sap I somehow missed pouring into the pot in the bottom...and yep it came out cloudy and yucky cottage-cheesy texture. Went down the drain. Was quick to go check the last 20l of sap I got yesterday, thank gawd it's still good. Now I get that started later today, maybe make batch #7 by evening, and of course pull spiles and clean equipment.
