Black on jar ring from fermentation

Hello
Two weeks in on my fermented peppers
The fermentation as stopped and I am seeing black mold ?
In lids.
What went wrong?☹️
Thanks 
Mark

Hi Mark,

I don’t think that is black mold in your lid I think it is the reaction in the metal from the acid and salt. You certainly don’t want to eat that but it is common and doesn’t harm your ferment. 

Wash the lid off and you can even put a piece of parchment paper between the lid and the jar so this can’t happen. 

Cheers, 

Kirsten

Hi Kirsten,
Thanks for the quick response.
One more question.
I have been burping for two weeks. But there is no off gassing(fizz) when I open jars as there had been.
This and the black stuff is what made me think my ferments had been compromised.
This is only my second batch to ferment. 
First batch I only fermented 10 days and still was off gassing when I made my hot sauce.
So I don’t have much perspective on the normal process.
Thanks so much for your help.
Mark

Hey Mark,

Good news! Off-gassing stops when the fermentation slows down, it means there is less sugar for the bacteria to be eating. All normal and part of the process!

Hope they are tasty,

Kirsten
