Measurement of L-malic acid content

Specialist laboratory test.

Method, device:  Enzymatic method, automatic wine analyser (spectrophotometric).

OIV standard: OIV-MA-AS313-26 

Sample volume:  10 ml

The research report is issued in the English language.

Malic acid is found in apples, naturally, but also in plums, pears and cherries. Knowing its quantity in the wine allows deciding whether to carry out malolactic fermentation. 

Wines with low content of this acid will be more microbiologically stable.
