I racked an IPA into a secondary glass carboy after 11 days in primary. I then dry hopped with 2 oz of cascade pellets. After two days most of the hop pellets have fallen except a thin layer a top. But now i'm seeing what looks to be yeast sediment cause its the same color as the sediment in the bottom of carboy clinging to the sides of the carboy. This is my first time using glass and i sanitized everything really good with star san. Its not just like one ring of sediment its in alot of different patches on the sides of the carboy. But there is none of this sediment looking stuff on top of the beer. I was just a little worried could this be mold. It dosent look like mold being it looks to be the same color as sediment in the bottom of carboy. Has this ever happen to anyone before? I used a 11g packet of dry yeast to ferment with. Fermentation went great and was complete after taking hydrometer reading for three days in a row and fg stayed the same. So if anyone could tell me what they think this is? Has anyone seen this before and should i be worried? Thanks in advance
