I picked up the grapes at the end of the day and am not familiar with the grower so do not know what other grapes he grows. I used Pasteur red yeast and it was a bit cold so primary fermentation took 12 days. I crushed and started MLF when the brix count was still 2 and used White Labs MLF bugs that come in a test tube. This was different that my ordinary process of waiting out primary fermentation, crushing, racking off the gross lees and then trying to start MLF. I have also used a powdered White Labs product in the past.
Maybe it was something in the new process or the different products used. If it is something funky that has gotten into the wine would filter pumping it help?
Thanks
