malolactic fermentation for dummies

To help give you an idea, wines such a Pinot Noir, Merlot and Cabernet can do quite well with the added influence of a malolactic fermentation. A malolactic fermentation (MLF) is a wine bacterial fermentation by Leuconostoc oenos or Lactobacillus spp, which converts malic acid into lactic acid and carbon dioxide. While an MLF can occur in the presence of Potassium Sorbate doing so will often produce a fowl odor, usually a strong geranium to ripe fish smell. This narrows down the field for the most part to big, heavy red wines. It may not be wise to try to stretch a culture to grow to do larger gallonage than designed because the bacteria is slow to grow. Malolactic fermentation is often very desirable in dry reds and in such dry white wines as Chardonnay and Viognier. Again, the starter needs to be prepared a couple of weeks before it is. It is a very natural process and one that can occur spontaneously if the conditions are right--usually after the yeast fermentation has completed. MLF involves bacteria instead of yeast, and it usually begins when primary fermentation is complete, around 0° Brix. So, if the must is treated before fermentation with sulfites such as Campden Tablets or Sodium Bisulfite--as you should--lingering amounts could easily interfere with the ability of an MLF to start. So in general keep MLF's away from wines made from fruits other than grapes.The same goes for lighter, fruitier wines made from grapes such as Zinfandel or Liebfraumilch. The thought is that the wine is warmest during fermentation, since the yeast is generating considerable heat as it converts sugar to carbon dioxide and alcohol. The idea here is to only consider wines that already have some of the same characters that an MLF produces so that they can be built upon or enhanced by the process. Malolactic fermentation: Optional process in which bacteria turn malic acid into lactic acid, softening wine. Studied viticulture and enology at UC Davis. All Rights Reserved. But, instead of turning these sugars into alcohol--like yeast does--they slowly convert these sugars into volatile acids such as acetic acid; the same acid that puts the sharp pucker in vinegar. Malolactic fermentation can produce a wine that has more complex vinous aromas and can improve biological stability in the wine. Already a member? As I see it, wanting to be good at something is only natural and very consistent with human nature. Did graduate work in France.

Temperatures warmer than this will promote unwanted bacterial growths.Wines that are extremely high in acid (very low pH) may have a hard time fermenting. It will also improve the pH. It only takes a few minutes to learn how to read pH and it will help you improve your wines. culture the preferred method used by most wineries today.

The flavor changes that go along with MLF can be incompatible with these wines’ fruity character). Not all of the malic acid is being turned into lactic acid. Consider full-bodied wines that already have some rich, earthy notes to them. Log In. The nutrient use is certainly good but not always required.

When the number increases, the wine has become less acidic. Ironic as this may seem, there are some wines that have acidity levels that are simply to far out of range to be corrected with a malolactic fermentation.

MLF involves bacteria instead of yeast, and it usually begins when primary fermentation is complete, around 0° Brix. Of course, temperature is really important: Malolactic bugs do not work well below 60° Fahrenheit. Malolactic fermentation (MLF) may sound mysterious, but it’s a technique every home winemaker should master. At the completion of malolactic fermentation, though, you will see that the number has shifted upwards.
