View Full Version : Black spots around gasket (!)

09-10-2011, 12:23 PM
Hello again. So the batch (http://www.gotmead.com/forum/showthread.php?t=18563) I recently thought might be bacterially soured (don't particularly think so anymore) now has a truly worrying sign.

Wedged in between the airlock gasket and the inside of the carboy neck, lately there have developed 4 or 5 little black spots, about the size of pinheads. Could be anything, really, but my uneducated eye thinks it's mold.

My question: should I immediately -- and very carefully -- rack to a verifiably sanitized container, even though primary fermentation has only been going for 9 days? Or would that stress the yeast and risk sticking?

I'm a mead newbee myself but as a brewer (and from the info shared with me on this site) I'd have to reccomend the "relax, don't worry have a homebrew" mindset. if you have a good fermentation going, most undesirables will have a difficult time displacing an active fermintation. if you have a spare air lock and stopper and a little food grade poison (my local package shop used to look at me funny when I refered to golden grain this way) it might make you feel better to sanitize a replacement stopper / lock, swab the inside of the neck with said food grade pioson and replace the offending stopper but I suspect you will be just fine.

It's a possibility, if I saw something look like it's growing between the stopper and carboy I'd probably remove and re-sanitize the stopper and then carefully using a tissue dipped in sanitizer, wipe the spots up out of the carboy, then re-insert the stopper...

If you do decide to rack to a clean carboy, I would suggest inserting the racking cane very carefully so you don't take anything down into the must, and then gently stir the lees back in so you bring most of the yeast along with your must, so you don't interrupt your fermentation.

You know, I hadn't even thought of just replacing the gasket and lock. Think I'll just go do that now. :)

And Riverat: I know now that baddies generally can't all of a sudden outcompete a good, fermenting yeast colony. Goodness knows I haven't lost sleep over it -- but the relaxing and not worrying is definitely helped by being able to ask these kinds of questions to people who'll answer!
