Unidentifiable sediment

[PSlattery]

Please if any one has had sediment that looks like this ever please let me know. The wine was made from grapes and has a 3.31 ph and the So2 was brought up to about 60 ppm about 1 month ago I wast planing on touching it for another 6 months but may rack off.
Other than that area in the carboy there isn’t much.

Could it possibly be tartaric acid crystals

How old is the wine and when did you last rack it?

 

[CoteRotie]

Looks like potassium tartrate with some anthocyanin pigment in it. If so, harmless.

This is from this spring so only 6 months old I racked it about 2 months ago. I also made a large acid adjustment and was hoping to do a cold stabilization this winter in the garage.
