Hey guys,
So I made I starter with WY1968, the first time I've used the strain. Everything was normal, 1.2L 1.038OG made with DME, pinch of yeast nutrient, put on stir plate at about 70F ambient. CO2 bubbles started within 6 hours or so.
THEN... I see this today after about 15 hours from pitch. It smells normal, and I believe in my sanitation practices as I have yet to have an infection or known contamination (knock on wood) since I started brewing 16 batches ago. The only thing I can think of is that the yeast flocculated once they were done with the starter wort, and just stayed clumped. After turning off the stir plate, the yeast settled FAST into a normal creamy layer. I know Fuller's is a super-floc'er, just wanted a second opinion. Anyone?
