Malo is "blocked" for the most part, as I understand it, by keeping vinification at cool temperatures. Since you don't get it in Rieslings, Chenin Blancs, etc. they are vinifying so it does not happen. When one wants to make sure it happens, other than using additives, one raises the temperature of vinification to induce the requisite yeasts to be more active.
No, actually that is not quite right. Without getting into a long-winded explanation, primary fermentation is done by yeasts, ML by bacteria. And the issue of fermentation temperature is more complex; suffice to say it is difficult for ML to happen in a very cold cellar, which is somewhat different than a temperature-controlled primary fermentation.
If it is difficult to happen in a cold cellar, what did I say that was not right (other than your important corrective that the fermentation occurs because of bacteria and not yeast)?
