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 antagonistic 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..
