RJ Spagnols White clumps top layer of carboy ?

Notice wine in 2ndary fermentation with white powdery clumps on top layer of liquid.
I rattled the carboy a little and saw them break up and dissipate some! What could this be?

Is this done fermenting? If not then this could be bacteria as you are very low in the carboy and need topping up badly! Did you recently add sulfites, especially campden tablets as they are notorious for not breaking up completely due to the fillers used to hold them together. Hopefully the later as thats just a unsightly problem, if its the first then you need to hit this with a stronger does of kmeta and top up to prevent this from getting any worse!

Yup, i agree with Wade.

I'm following the Super Tuscan kit instructions exactly! It said to squeeze out the sock containing grapes after 7 days (did this on Sunday) and leave for an additional 7 days racked into Carboy (2ndary fermentation). On Sunday I will add the KMeta and Sorbate, etc.. to clarify. I have not topped off yet as it states NOT to until the next step. Thoughts?

Okay short period of time rules out infection in my book so that's good and campden tablet is out also. This leads me to think that maybe it is the cleaning agent you used on carbohydrates. Do use a oxygen based cleanser like B brite? These have a tendency to build up on the insides of carboys especially it they don't get rinsed. Are you possibly use a no-rinse Sanitizer?

I know when I clean MY carbohydrates, I always use something like b-bite.

Stupid phone!

Just a thought from another thread, but is this the batch that was made to 5 gallons instead of 6?

I use that to clean my calories as well
