The word "malolactic" refers to a process that happens in winemaking, where malic acid in the wine is converted into lactic acid. This process can make the wine taste less tart and more smooth.
It's also gone through malolactic fermentation (a.k.a. «malo»), the natural process of malic acids (think of a tart green apple taste), turning into lactic acid (think a buttery or milk flavor). (bonappetit.com)

The Australian Wine Research Institute has developed a new robotic liquid handling system which, it claims takes malolactic fermentation research to the «high - throughput» era. (fmtmagazine.in)
