Hi all! Been brewing for a few years and finally joined the site! I've had a reoccurring issue over the last few years when bottling beers with certain yeasts and always wondered what it could be. I haven't seen anyone else mention similar issues but thought I needed to throw it out there and see if anyone else had similar experiences. I've had a few batches, that when bottle conditioned, would develop a dusting of particles on the walls of the bottles and sometimes a thin layer of residue floating on the top of the beer in the neck of the bottle. I would sometimes agitate the bottles which would help some of the residue drop to the bottom. I've had this experience when brewing with 3711, 1214 and the latest, 3522, which I'm attaching a picture of the bottle. For the most part the beers have all been great tasting except for one, which after conditioning for several months developed a strong doughy, peachy flavor. Had to pour it out it was so bad. The picture attached is a belgian pale (all extract) after only 3 days in the bottle. I tasted a sample and it had a hint of the same peachy flavor with some burnt rubber thrown in. Hoping that clears up with some aging. The same day, I bottled an Oak aged Belgian stout using 3787 that doesn't show any of the same residue. In fact I have two other beers using 3787 that carbonated and conditioned without the residue. I keep worrying that this is some kind of infection and am apprehensive about brewing a next batch. Any incites would be greatly appreciated. Thanks!
