Hello Joel,
     Here in the U.S.,  companies that sell beer making supplies sometimes
sell the acetobacter starter (mother) to make vinager.Basically vinager is
made by acetobacter bacteria that eat alcohol and produce acid. There should
be beer making suppliers on the internet, maybe they could help You more,
Your question seemed to draw a blank the last time I saw it, good luck in
Your search.
