Malolactic fermentation is employed in nearly all major wine-producing regions, though its use and management vary significantly depending on tradition, climate, and wine style. In cool-climate areas such as Burgundy and Champagne, MLF is a routine part of red wine vinification and is also frequently applied to white wines to temper high acidity.<ref>Robinson (ed.), *The Oxford Companion to Wine*, Oxford University Press, 2015, p. 431.</ref>

In New World regions like California and Australia, where grapes can be harvested with lower natural acidity, winemakers often consider whether MLF is necessary or desirable on a case-by-case basis. For fuller-bodied white wines such as barrel-aged Chardonnay, MLF is widely used to enhance texture and aromatic profile.<ref>Goode, *The Science of Wine: From Vine to Glass*, University of California Press, 2014, p. 91.</ref>

In sparkling wine production, particularly in the Champagne region, MLF is typically encouraged to reduce sharp malic acidity and create a more harmonious base wine. However, some producers may inhibit MLF deliberately to preserve tension and precision in the final cuvée.<ref>Comité Champagne, “Malolactic Fermentation in Wine”, wineserver.ucdavis.edu</ref>

MLF is almost universal in red wine production worldwide, with very few exceptions. Even in traditionally high-acid wines such as Barolo or Rioja, the process is considered essential for balance, ageing potential, and microbial stability.
