MLF in must

[MCARCIERO]

Is MLF recommended for must?

Wait until primary fermentation is about over to begin mlf. Before that it is generally not done.

Just curious, at what SG would you start Mlf? Would you always introduce another yeast?

I did mine at 1.002 and another 1.004. I was told by people in the wine club im in to start before it drops below 1.000. Also you may want to add a bit of yeast nutrient too during this process. Good luck.

MLF is caused by bacteria, not yeast. Yeast nutrient isn't advisable for feeding them. I would opt for something specifically formulated for MLF like an Opti-Malo plus. You don't want to give the bad microorganisms food to work with to ruin your wine.

And wine will typically naturally undergo MLF but using a specific strain is more reliable.

Not all varieties of wine should go through MLF. Also, if the acid level is already low, it doesn't necessarily need to go through MLF, anyway.
