So I've never had this happen before and I'm not sure what's going on. I transfered to the secondary, added the dry hops a few days later and this is happening.
It just looks like yeast-rafts to me. I rarely transfer to secondary, but when I have done so I've found that some yeasts (particularly English strains) start a fresh krausen.
Okay thanks. I always transfer to secondary. I have another batch right beside it that has none of this and like I said, never seen this before. Both have the same yeast, which is what I use 75% of the time, which is US-05
