Hi all, I brewed a second 5gal batch of Bohemian pils from harvested yeast from the first batch (wyeast urquell 2001). Washed the yeast made a starter, had some good airlock activity from day 2-5 in 49-51F basement, not as robust as the first batch but it was there. OG 1.044, after week and half 1.010-1.008. However Ive noticed as I was taking a sample the sour smell and yellow orange floaties all over the top. Tastes a bit sour, but that smell and the presence of all that still material up top makes me wonder if there is an infection. 4th all grain batch so a bit concerned as none of my other batches looked or smelled like this. Does it look infected or am i overreacting? Many thanks.
Recipe:
