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: One of the three primary acids, along with tartaric and citric, that occur naturally in grapes and play a part in the flavour and acidity of wine.

Malic acid
The organic acid found in apples, grapes and wine. Malic acid is converted to lactic acid during malolactic fermentation.

Malic acid :
Acid abundant in green grapes and which gives a tarty taste to the wine.
Malolactic fermentation : ...

Malic acid, on the other hand, is frequently described as overly harsh, sharp and with a green taste like an unripe apple.

Malic acid Sharp, appley acid.
Malolactic Fermentation Abreviated to MLF. Conversion of harsh Malic acid to a softer Lactic acid, and carbondioxide.

malic acid, the sharp, appley acid most notable in grapes from cool years.

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—The "apple" acid found naturally in grapes which can be converted to lactic acid during Malolactic Fermentation.

Malic acid
An acid in wine which adds a hard or sharp taste to wine. High concentrations of malic acid are undesirable. It is reduced through intentional malolactic fermentation.
Malolactic fermentation ...

Malic Acid
particularly raw, "appley" acid in grapes
grape used to make sweet Madeira ...

Malic acid (Malique)
Malic acid, which occurs naturally in many wines, is transformed into lactic acid during malolactic fermentation.

Malic acid: A natural organic acid which occurs in ripe grapes in relatively high concentrations. It is the second most abundant organic acid in most varieties.

Malic acid See 'acids', 'malolactic fermentation'.
Malolactic fermentation Transformation (not technically a fermentation at all) in which the tart tasting malic acid present in young wine is transformed into the softer lactic acid.

Malic acid
One of the main contributors to the acidity of a wine. Malic acid has a sharp, green apple like taste.

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.

One gram of malic acid converts roughly into 0.67 grams of lactic acid and 0.33 grams of CO2.
WHY USE IT? There are several reasons: ...

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. 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.

Malic acid has a green apple-like flavour in young grapes, which recedes during the ripening cycle.
White grape variety. Portuguese.

Grapes contain malic acid, and it remains in the wines after primary fermentation. This tart-tasting acid imparts a sour green-apple note to unfinished wines.

Malic acid
Malic acid is a major component of a wine's acidity. It has a sharp taste that reminds one of a tangy green apple. This taste may be appreciated in white wines, however, it is usually not appreciated in reds.

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 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).

This is basically a bacteria fermentation that converts Malic acid into the softer lactic acid. The byproduct creates another ester known as diacetyl, which many of us refer to as butter.

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.

What happens during this fermentation is that malic acid, which has a sharp flavor, is acted on by special bacteria. This usually takes place in a barrel set aside for this purpose.
