 EMI2.1 
 alkoholische Gärung vollkommen geeignet werden. Tatsächlich zeigt die mikroskopische Prüfung. dass sich die Natur der Maischen durch Auftreten einer deutlichen Floekung gewisser Stoffe verändert hat und dass die Maischen praktisch vollkommen bakterienfrei sind. 



   Die angestrebte Wirkung kann durch Veränderung der angewendeten Temperatur, beispielsweise zwischen   80-140  C   und der Säuremengen geregelt werden. Es sind zahlreiche Säuren für den angegebenen Zweck geeignet. Nur beispielsweise seien genannt : Schwefelsäure, Salzsäure, Essigsäure und Trichloressigsäure. Die Säuremenge kann sieh beispielsweise zwischen 1 g und 5 g pro Liter bewegen, wobei man einen Teil der zugesetzten Säure nachträglich durch Zugabe eines Alkalis neutralisieren kann.

 EMI2.1
 alcoholic fermentation will be perfectly suitable. Indeed, microscopic examination shows. that the nature of the mash has changed due to the occurrence of a clear flocculation of certain substances and that the mash is practically completely free of bacteria.



   The desired effect can be regulated by changing the temperature used, for example between 80-140 C and the amount of acid. Numerous acids are suitable for the stated purpose. The following are only mentioned as examples: sulfuric acid, hydrochloric acid, acetic acid and trichloroacetic acid. The amount of acid can move, for example, between 1 g and 5 g per liter, and part of the acid added can be subsequently neutralized by adding an alkali.
