Completely Working Potion Brewery! Read the book in the chest for instructions!
Using simple mechanics, this potion brewery can be extened to put as much ingredients as you would like! 
[I have not seen anybody else create this potion brewery before, If you find this posted somewhere else, before I made this, please tell me and I will take this down.]
I hope that this is helpful in your minecraft adventures!
 -Later!
