MaloBacti MLF BACTERIA
Unique strains for natural colour, aroma and flavour stability
MaloBacti™ MLF Bacteria represent a unique range of freeze-dried MLF starter cultures of Oenococcus oeni possessing special attributes that provide winemakers with added choice and flexibility in both application and outcome. MaloBacti™ MLF bacteria are not only selected for their efficient degradation of malic acid, but primarily to provide winemakers with different tools to manage the desired flavour and aroma profile of their wine.
Zert, Nr.: 4-01612-2014
Can be used in organic winemaking according to following regulations: (EG) Nr. 834/2007 and (EG) 889/2008.

MaloBacti™ Flavour Management
MaloBacti™ starter cultures not only allow a reliable and easy MLF in wine, but also provide a characteristic aromatic profile for the sophisticated flavour management in modern winemaking.
The picture shows the aromatic profiles of the different MaloBacti™ MLF starter cultures in wine. HF2 and AF3 show quite balanced aromatic profiles, AF3 with a focus on black berries, HF2 with more emphasis on red berries. CN1 strongly enhances the varietal character of the terroir and pronounces flavours of red berries. None of the three strains show any undesired buttery diacetyl flavour.
MaloControl BIO
Special nutrition supplement for the support of MLF bacteria metabolism
Stuck or sluggish malolactic fermentations (MLF) are still present problems in the wine industry. The reasons for sluggish MLFs are multiple. The main inhibitory factor is an elevated SO2 content in the subject wine. Elevated levels of SO2 evolve from the primary fermentation due to the lack of essential nutrition. To overcome this problem, 2B has developed MaloControl™ to balance the nutrition for the MLF bacteria.
MLF bacteria have a specific requirement of nutrition that is different to yeast. This specific nutrition requirement is an important factor when considering a successful MLF.
Addition Guide
Improves bacteria metabolism and absorbs inhibitory substances, recommended for:
- Harsh wine conditions e.g. >15% alc; pH < 3.2; TSO2 >40ppm.
- Nutrient deficient fruit – low YANs, disease, dry-grown.
- Wines with previous MLF difficulties and for re-inoculations.
| Condition | Dosage |
|---|---|
| > 120 ppm YAN | 4g/hL |
| < 120 ppm YAN | 8g/hL |
Properties
- Provides a balanced combination of all essential amino acids and trace elements for MLF bacteria
- Absorbs inhibitory substances in the base wine (e.g. medium chain fatty acids)
- Diminishes the typical MLF character in all wines
- Low dosage rate due to high concentration of supplements
