I've had this happen on a couple of batches recently. One a SMaSH blonde, one a dry-hopped pale ale. Hydro readings on both were 1.008 before kegging, so they were fully attenuated. (Hydrometer was checked with distilled water. Used California Ale with both.) Force carbed up to 2.5 volumes. For the first three weeks they drank great and I have gotten rave reviews on them. They've been in the keg for about a month and a half now, and I pulled a pint of the pale ale last night and it finished sweeter then it did in the beginning. My wife didn't notice until I pointed it out, but it is definitely different.
What could be causing this? Is there an infection that causes sweetness? My cleaning and sanitation regiment is pretty strict. I only have two CO2 lines running four kegs (next purchase is a gas manifold) so they were a little under-carbed. Could that have caused it?
These are two of my "house" beers that I've never had problems with before and two that I can't afford to have problems with. Ideas? Suggestions?
