I have actually experienced this on my last 2 batches, but not the ones before that..

My regimen:
rehydrate yeast on stir plate pitch at 60f, ferment at 64 ambient, start raising temp 1 degree per day after about 3-4 days, until I get to 68. Ensure fermentation is over via hydrometer, then crash cool to 32f. Wait a few days, add gelatin and rack to keg.

As I said before my last 2 batches have a slightly fruity, slight clove DOMINENT flavor to them that was not there on racking. As this is my standard procedure for all my beers, and have been doing said procedure for many years...I am sort of baffled. I do think I purchased the us05 from 2 different stores, so maybe it is one store (midwest supplies), but not the other (lhbs). Or could be the knox gelatin, but again I have done this procedure literally hundreds of times before with not seeing these flavors.

@ Gameface, BigFloyd, I do appreciate the feedback and will pitch at my fermentation temps from now on.

@rabeb25, we may be on to something. We have the yeast and gelatin in common, but my gelatin was very old so it's going to be different production date, lot #, etc. The yeast however I purchased from my LHBS about six weeks ago. I'm wondering if there's maybe a bad batch going around. Guess we'll have to stay tuned and see if the problem creeps up on anyone else using US-05 in the past month or so. The fruity flavor your describing is most likely from fermenting on the low end of the temp range with this yeast. I've read multiple accounts of people experiencing a peachy/apricot flavor when fermented at the lower temps. I was surprised I didn't encounter that myself, but it was probably overpowered by the phenolic/belgian/colve flavors I had going on. Interestingly enough I didn't taste it in any of my hydro samples either. It wasn't until I put it on gas and tried it a few days later.

I don't think so I have never gotten the peach flavors from my fermenting regimen with us05. This is more of a blueberry, and orange, with clove notes. Reminds me of a wit and a hefe crossbreed. These beers were a cream ale, and a blonde ale, so it really comes out. The weird thing is the last cream ale I did (I always keep one on tap, this new one was to replace that beer when the keg kicked), had absolutely none of that. I know for a fact the old cream ale was with yeast from a LHBS, and the other packs were from midwest, and were purchased probably 6 weeks ago as well.
