MBR 41 was isolated in the Abruzzi region of Italy during an extensive European Union collaboration for use in red and white wines. MBR 41 was chosen for its good implantation, steady fermentation, high alcohol tolerance (up to 15% v/v), enhanced mouthfeel and wine structure. This strain will ferment well with a pH above 3.2 and total SO2 levels up to 50-60 ppm. In red wines, increased spicy, cherry and red fruit flavors have been noted. Red and white wines fermented with MBR 41 have increased richness and complexity.
You can't store malolactic bacteria once the package has been opened. Note: Malolactic bacteria added during the ferment will compete with the yeast for nutrients and are atagonistic to yeast, sometimes causing problems resulting in stuck or stalled fermentations. The best time to add an ML culture is after racking off the gross lees.
