How could you possibly extract any items from the brewing stand without a hopper. It seems to me you are asking for something that is literally impossible. I am not even sure if a dropper or dispenser can inject an item into a brewing stand but I am quite sure I cannot think of any way to extract an item without a hopper or hopper-cart [other than a command block but then there would be no point as you could create whatever you needed from the command block and skip the brewing stand altogether]. I do not believe this is a valid request, I believe it to be impossible.

You won't be and to extract, but you could load water bottles and ingredients via dropper and load the droopers up with hoppers. This would be semi automatic, allowing you to press a button, or one of many buttons, and brew three of the potions of your choice, then manually extract them.
I didnt know if it was possible or not. The server i am on, hoppers wont interact with brewing stands, so thats why i asked here if it were possible. Thanks
I thought hoppers wont interact with brewing stands properly because of a recent bug, not a server setting!? I built MumboJumbo's machine on my SP world, and the stand wont deposit the finished potions into the chest after the first time, unless you reload the chunks ... what I'm saying is maybe it will be fixed soon if that's your issue ...
