Malic acid
From EncycloWine
Malic acid is a tart-tasting organic dicarboxylic acid that plays a role in many sour or tart foods. In its ionised form it is malate, an intermediate of the TCA cycle along with fumarate.
Malic acid
One of the main contributors to the acidity of a wine. Malic acid has a sharp, green taste - rather like the tangy freshness of a green apple. Whereas this may be desirable in some white wines, in others, and in most reds, it is not.
Malic Acid
The main acid of apples and also one of the acids found in grapes.
It encourages rapid fermentation and assists in producing aroma and flavour. Malic acid has a sharp, green taste - rather like the tangy freshness of a green apple.
malic acid : One of the two primary acids found naturally in grapes. Malic acid levels are higher in grapes grown in cool climates or under dense shaded grapevine canopies.
Malic acid
The organic acid found in apples, grapes and wine. Malic acid is converted to lactic acid during malolactic fermentation.

Maturity: The period in a wines life that can be described "after youth but before its decline". It can be 3 years or 3 decades depending on the wine.
Malic Acid: A naturally occurring acid, also one of the predominant acids, found in grapes.
Malic Acid - A naturally occurring acid in many wines that is characterized by the sharp crisp acid in a 'Granny Smith' cooking apple. This acid is often reduced in a wine through the use of malolactic fermentation.

Malic acid
An acid found in high concentrations in unripe grapes, it has a tart, sharp flavour. It is lost as the grapes ripen, which is one reason why wines from very warm climates often have a low natural acidity and can taste *flabby.
Malic acid: A natural organic acid that occurs in ripe grapes at relatively high concentrations. It is the second most abundant organic acid in most vinifera varieties. Tartaric acid, of course, is the primary grape acid in nearly all varieties.
Malic Acid A sharp, tart acid found in grapes as well as in green apples. Less-ripe grapes or grapes grown in cooler climates can contain high levels of malic acid; the resulting wines often contain aromas and flavors reminiscent of green apples.
Malic acid reacts in the same way as tartaric acid; however, malic acid (H2M-) does not respond the way tartaric acid does to carbonate treatment, ...
Malic acid. common acid in grapes which gives a bright crisp element to the wine.
MALIC ACID: Mainly found in apples, bananas, pears & stoned fruit. It has a sharp, green (appley) taste which may be desirable in some white wines, in others (especially reds) it is not.
Transformation of malic acid into lactic acid using bacteria. In Rioja and Navarra, malolactic fermentation usually occurs spontaneously some weeks or even months after alcoholic fermentation.
This acid, which is also found in milk, makes a much softer impression on the palate than many others, such as malic acid.
Tartness, the taste of natural fruit acids (tartaric, citric, malic or lactic) in wine. Minute traces of other acids are all found in wine. There are two measures of acidity used in winemaking; see pH and Titratable acidity.
American Oak ...
Acid/ Acidity : Acids, primarly citric, malic and tartaric, occur naturally in wine and, in the proper proportion, are essential ingredients, giving the wine character and helping it age.
Derived from natural grape acids, primarily tartaric and malic, but may also include lactic and acetic from microbial action, whether intentional or otherwise.
MALIQUE (MALIC)
Acid malic. Acid present in a natural state in much of wines and which is transformed into lactic acid by malolactic fermentation.
MANSENG
Gros manseng and petit manseng are the two basic white type of vines of the jurançon.
The major wine acids include acetic, carbonic, citric, lactic, malic, and tartaric. Excessive acid makes a wine taste sour, while insufficient acid renders a wine weak.
The natural acids that appear in wine are citric, tartaric, malic and lactic. Wines from hot years tend to be lower in acidity, whereas wines from cool, rainy years tend to be high in acidity.
Malolactic fermentation Also known as malo or MLF, a secondary fermentation in wines by lactic acid bacteria during which tart-tasting malic acid is converted to softer tasting lactic acid. Marc French for "fruit skins". See "pomace".
These bacteria convert malic acid - naturally present in fruits like grapes and apples - to lactic acid, which reduces the acidity of the wine and improves its flavor.
This is the conversion by bacteria (lactobacillus) of some of the malic acid naturally present in grapes into lactic acid. Malolactic has the effect of "softening" the wine, taking some of the sharp edge off.
Winemakers who barrel-ferment their white wines often put them through a secondary fermentation, common to virtually all red wines, in which the malic acid naturally occurring in wine grapes is converted into lactic acid.
Lactic acid bacteria have a useful role in winemaking converting malic acid to lactic acid in malolactic fermentation.
Peculiar characteristic of this wine, thanks to the high quantity of malic acid and the lively total acidity, is its vocation to be sparkled, fermented in bottle (Champenoise method) or in autoclave (Charmat method).
Since malolactic fermentation is all about having the wine's malic (apple style) acid get converted into lactic (milk style) acid, by doing a chromatogram you can see visually where the wine is in the process.
citric, lactic, malic and tartaric. Desirable acid content on dry wines falls between 0.6% and 0.75% of
thers being "Acid", "residual Sugar" (and/or "Glycerin") and "Tannin". The presence of these
components define a wine that has "good balance".
Malolactic conversion: a conversion by bacteria of the malic acid in wines into lactic acid which results in a lowering of the overall acidity, and, hence, tartness of the wine.
Winemaker Andrea Faccio ferments the juice in stainless steel and allows it to go through a full malolactic (this is geek talk for a second fermentation, whereby malic acid is converted to lactic acid, and the result is a smoother, rounder, ...
Chardonnay is encouraged to undergo a second fermentation, called Malolactic Fermentation: Bacterial fermentation in which malic acid is converted to lactic acid and carbon dioxide, adding complexity to and 'softening' wines.', '', 250)"; ...
Composed of roughly 85% water, 12% ethyl alcohol, a touch of tartaric, malic and several other acids, wine also contains various sugars and carbohydrates, less common alcohols, aromatic aldehydes, ketones, phenolics, enzymes, pigments, many vitamins, ...
Malolactic fermentation: A secondary fermentation in which the more tart malic acid in a wine is converted by lactic bacteria into softer lactic acid and carbon dioxide.
Malolactic fermentation is desirable when new wines are too high in malic acid, as in Germany, or when particular nuances of taste and flavour are desired, as in the red wines of Burgundy and Bordeaux in France.
Malic, citric and tartaric acids come from the grape; lactic acid converts the malic acid to a softer one during fermentation. The oxidation of alcohol can cause acetic acid, sometimes referred to as volatile acidity.
Malolactic fermentation is a process in which lactic acid bacteria converts the harsher malic acids (think green apple pucker) in the juice into lactic acid (think creamy milk) to produce a softer mouth feel and overall a more inviting palate ...
Its action converts the naturally occurring Malic acid into Lactic acid plus Carbon Dioxide gas. Reduces total acidity by this action.
A secondary fermentation that changes the tart malic acid (found in green apples) into the softer lactic acid, found in milk. Common in red wine, but used almost exclusively in Chardonnay for white.
add "Acid Mixture A" which consists of 50% tartaric acid, 30% malic acid and 20% citric acid. If the must is acid-deficient but measures higher than 4.5 p.p.t.
Wine chemists enumerate all sorts of different acids in wine - volatile acidity (acetic acid, i.e., vinegar), and fixed acidity (a variety of acids, primarily tartaric and malic, plus citric, succinic, and lactic acids).
It is the process during which the malic acid of wine changes into lactic acid and carbonic gas under the action of bacteria living in the wine. Malic acid is harsh, it is changed into lactic acid supple and stable.
Normally occurs after alcohol fermentation when bacteria convert malic acid into lactic acid. Lactic acid is not as strong as malic acid which means that the process has a softening effect on the wine and enhances the flavour slightly.
Is a natural (or sometimes induced) winemaking process whereby tart-tasting malic acid, which is naturally present in grape must, is converted to softer-tasting, less aggressive lactic acid, resulting in a smoother, more creamy wine with a fuller, ...
Malolactic Fermentation: The bacterial conversion of the crisper, apple-type malic acid to the softer, milk-type lactic acid in wine.
Fermentación Maloláctica (malolactic fermentation) Transformation of malic acid into lactic acid through the action of certain bacteria. It is an almost essential process in the making of quality tinto wines, since this is how they become smooth.
A natural process during which beneficial bacteria convert the malic (very tart) acid in a wine to lactic (softer tasting) acid. Malolactic fermentation can take place on its own or be prompted by the winemaker.

Malolactic Fermentation
A bacterial process that converts harsh malic acid into creamy lactic acid. Desirable in French-styled Chardonnay and fine reds.
Mature
Fully developed, ready to drink.
A wine-making process in which the wine is put through a special fermentation that converts its malic acid into lactic acid. The result is a soft, mellower wine that some wine lovers find "flabby" but that's very popular in the marketplace.
Malolactic: A wine-making process in which the wine is put through a special fermentation that converts its malic acid into lactic acid.
This is the conversion that turns harsh-tasting malic acid into softer lactic acid.
