Description
- Control and monitor Malic Acid and completion of Malolactic Fermentation in wines
- Quantitatively measures from 0 – 500 mg/L
- Every kit comes with ten strips and ten samplers and requires no extra chemicals or instrumentation for accurate readings
- Accuvin strips have a unique construction enabling the removal of pigments from red wines making them usable on any wine
- No sample prep required, enabling you to get actionable results in a matter of minutes!
The Accuvin Malolactic Test Kit monitors the decrease in malic acid resulting from malo fermentation in wine. The test range is 0 – 500 mg/L.
WHAT IS MALOLACTIC FERMENTATION?
Malolactic fermentation, the secondary fermentation in winemaking, reduces total titratable acidity by adjusting the relative concentrations of L-malic and L-lactic acids. This softens the wine and allows it to develop mellowness and full-bodiedness. This process also results in microbial stability since one of the critical ingredients of spoilage is removed. You can read more about malolactic acid, malic acid tests, and the chemistry behind how they work in our free ebook.
WHY SHOULD A WINEMAKER USE MALIC ACID TESTS?
Accuvin has developed a unique membrane built into each test strip that selectively removes interfering color pigments. Thus, this kit can be used for red and white wines and requires no adjustments or pretreatments. Â
Keeping track of the progress of malolactic fermentation allows the detection of problems when they are small and require less intervention to fix. Our secondary fermentation test strips are an ideal method of determining the completion of MLF and provide many of the world’s most regarded winemakers with an ideal primary method for testing. The highly portable nature of our tests and their rapid results make them a commonly used method for confirmation of MLF completion. It is also often used before paper chromatography to determine which barrels are ready for a more precise but slower testing method.
Monitor with our Malic Acid Test Kit to know where your wine is in the MLF process at any moment.
Track MLF by the barrel or at various depths of a large tank with our Malic Acid Tests, so you will not have to assume MLF is progressing similarly throughout with a combined sample.
Monitoring with Malic Acid Tests lets you stop MLF at 75 mg/L, 50 mg/L or 0 mg/L, allowing you to choose how soft, mellow, or full-bodied you want your wines.
At harvest, you can monitor the decrease in malic acid with tests to quantify the reduction of malic acid as grapes approach optimum ripeness. Malic acid levels decrease faster than tartaric acid levels, especially in warmer areas. This enables finer control over when to pick.
Our Malic Acid Test Strips monitor the decrease in malic acid from 500 mg/L to 0 mg/L, indicating the completion of malolactic fermentation. No color indicates a malic acid concentration at or near 0 mg/L. Test kits contain the number of tests and samplers that correspond to the size of the kit.
