I've got a two-gallon batch of a pale-ish ale dry hopping in a carboy and I'm looking for a bit of advice on how to proceed. Had it in primary for about 8 days before racking to secondary on top of a half ounce of loose Cascade pellets. It was my first attempt at dry hopping, so I was a little curious upon finding a layer of hop debris floating at/near the top of the beer.
About 6 or 7 days later about 40% of the debris had dropped from the surface. Some of it was hanging out just below the surface and some seemed to have dropped to the bottom. Hoping to bottle in the next few days, I moved the carboy to the basement where it's significantly colder. Within a two days, about 99% of the surface of the beer was clear of debris. I moved the carboy upstairs again to its original location to warm it up prior to bottling. Now a day later, the debris has resurfaced and has formed another layer on top of the beer.
My question is - how long should I wait for this stuff to settle to the bottom? Is it typical to have a layer on top like this after a week and a half? Obviously bagging the hops would have helped with the debris, but it's a little too late for that now.
Any advice? Thanks in advance.
