Presto 10g fermentation arrester

As the name suggests, the fermentation arrester stops the fermentation of the wine. If the fermentation is not stopped, i.e. the yeast is not "killed", the wine may ferment in the bottles under favorable conditions and cause great damage. Also in terms of the wine's shelf life, the use of a fermentation stopper is more than desirable.
