I had one of those last week openeing my first bottle of Ed's Hause Ale. (I brewed it not Ed)Only mine was 2-3 blobs instead of a long string. Maybe cause it was in a Red Stripe Stubby. It tasted horrible and moldy. So i put two more in the fridge for the next night. The next ones the next day showed no signs of the creatures but had the same gross effect so i think it's safe to say it had nothing to do with the off flavor as confirmed buy yours being good. I just appearently somehow messed up the whole batch. letting it sit and trying one every couple weeks to see if the nastiness goes away.
