Wine refining: Astribal and M2 and M8 lysates
At LEV2050 we have different products developed through our R&D Department, looking for new, bio-sustainable solutions for the food chain. Today we are going to talk about several products created especially for the refinement of finished wines: Astribal and the yeast lysates, M2 and M8.
ASTRIBAL

ASTRIBAL is a patented product composed of a lysate of Lactobacillus brevis lactic acid bacteria. It has a lower Z-potential (higher negative charge) which gives it a higher reactivity when interacting with phenolic compounds in red wines.
This product offers multiple advantages. Firstly, it improves the overall colloidal stability of the wine. In addition, it corrects aggressive tannins and/or the lack of volume in the wine. Finally, it increases the aromatic complexity of the wine.
LYSATES
M2 and M8 are Non-Saccharomyces yeast lysates with differential cell wall protein and polysaccharide compositions. They can be used as organic nutrition in fermentation or as refinement of finished wines, helping to reduce aggressive sensations, bitterness and astringency.
The method of use of both lysates is simple. Here are the steps to follow:
- Shake the container to homogenise the contents.
- Add to the wine to be treated
- Homogenise and leave to act for 5-6 days.
- Filter before bottling

M2 lysate consists of a yeast lysate from a strain very rich in parietal polysaccharides. This product is recommended for white, red, rosé and sparkling wines. It improves the sensation of sweetness and volume. It also reduces aggressive sensations, bitterness and astringency. Its normal dosage of use is between 0.05ml – 0.3ml per litre of wine. Its maximum dosage is 0.5ml per litre of wine.
The M8 lysate consists of a yeast lysate from a strain that is very rich in a higher percentage of parietal proteins. This product is recommended for red wines. It improves the structural sensation. Like the M2 lysate, the M8 lysate also reduces aggressive sensations, bitterness and astringency. Its normal dosage of use is between 0.05ml – 0.3ml per litre of wine. Its maximum dosage is 0.5ml per litre of wine.
