Biogen M (1 liter), Fruit acid concentrate, 1 liter
When Biogen M fruit acid concentrate is added, the mash adjusts to the right pH value if the acid already present in the fruit is insufficient to prevent faulty fermentation and mycoderma. Adding it once at the beginning of fermentation is enough. The pH value will then remain constant during the entire duration of the fermentation. Dosage: 200 to 400 ml per 100 litres of mash.
