I cannot reproduce this

I believe I found an issue in some recent contributed code that could cause this, which is now fixed

Basically you can fill a brewingstand with pipes, but the bottles don't get taken out of the container. That way it's duping th bottles. I made another video with the most simple setup I could think of. Just a chest, with a Redstone lamp as indicator if the bottle is still in it. And a pipe from the chests to the brewingstand with a lever to trigger.

I hope this helps :)
