I got a good look at it with a jewelers type magnifying glass.
I initially thought bore bug larvae because I was already aware of them as issues on barrels. But actually resembles the fruitfly larvae a little more. the leak has been off and on for a couple weeks now and I have shoo’d off fruit flies multiple times.
I would clean and spray down with k-meta solution but apparently not enough.
Main concern is others getting through into the wine. I suppose they would suffocate and die tho.
