Yet another "What is this in my Carboy" thread

[AnchorBock]

Second batch of mead, first tasted terrible! I'm hoping things go well with this one. I started it on Saturday, it's just a 1 gallon batch with 2 lbs of clover honey, nutrient, engergizer and Lalvin D-47. I added more Energizer and Nutrient (little less then 1/4 teaspoon of each) on Sunday and aerated a little bit and on Monday night I noticed this started forming in the neck of the carboy and it got more pronounced today (pic taken tonight, 4 days into primary):



Any need to worry? It could easily be nutrient that didn't get mixed in well I think because I just dropped it in and slowly tipped the carboy with a solid stopper until there was no nutrient sitting on top anymore. Thanks for any replies.

Looks like yeast to me, although I've never used nutrient. RDWHAHB

To me, it looks like your mead foamed up a bit during vigorous fermentation while you weren't looking, then settled back down again leaving a trail on the bottle. I had similar...whatever you call it... on the mead carboy of my MAOM and that turned out just fine *hiccup*.

It does not look like anything to worry about. If you are ever worried about infection, check out the infection thread and see what REAL trouble looks like: https://www.homebrewtalk.com/f39/post-your-infection-71400/
Granted, most of the posts in that thread are about beers not meads, but you still get the point.

Anyone ever get infected mead around here?

I had a similar looking thing with my Graff's cider. Fermentation really kicked up, foamed, receded, and left something looking like that. I wouldn't worry.
