White wine varietals like Sauvignon Blanc, Viognier, and Riesling, for example, often do not undergo any malolactic fermentation. These wines are recognized for their high acid levels and crisp finish.
What Wines Undergo Malolactic Fermentation? Nearly all red wines and some white wines (such as Chardonnay and Viognier) undergo malolactic fermentation. One way to recognize MLF in a wine is to note if it has a creamy, oily mid-palate texture. This can indicate malo (or also lees aging).
