Hey guys, first post here. So this was an all grain hefeweizen that I added some blueberry extract to. It was fine in secondary for about a week, but about 5 days after I added the blueberry extract this showed up. The only thing that touched the beer(aside from the extract) was a thief which was covered in star san foam. I added the extract straight from the bottle, and in retrospect maybe I should have sanitized it some how.

Sorry about the picture quality, but it's basically a white foam with hard white dome shaped bubbles on top. Does anyone have any idea what it is? More importantly, I tasted it and it seems fine. Am I ok to go ahead and try and rack from underneath the film and bottle it?

Thanks!

Indeed I do, and I do believe I know where you're going with this..but correct me please if I'm wrong. I use star san to sanitize everything, but the minuet amounts that is residual from the carboy is irrelevant as it sufacting capabilities degrades when beer takes its place in the carboy. That and I never had a similar situation happen to me before. I've been extremely lazy to plate or to evaluate the contamination in the scope...lol. But just in case, we'll hold that hypothesis up in the air as for science. Anything is possible.

I plan on kegging this bad boy either tomorrow or next weekend. I will repost my findings with a picture of what I found under the scope. I also want to take a gc/ms headspace sample to see what coffee components made it through the final product.

Yuck. Looking at those bubbles on that stout after adding coffee has me pretty leery to pop some beans I've had sitting in some bourbon for a week into my breakfast stout I've got going on. It's been in primary for 3 weeks, and is a pretty expensive recipe! I've got a labor of love going on and I'll be damned if 2 oz of coffee will bring me down.
