Welcome back! Today I have a FULLY AUTOMATIC BREWING STATION! But that's not all. The special thing isn't that you don't have to do anything to brew potions, the real special thing is that this automatic brewing station is completely 1 BLOCK WIDE! You'll have to see it to believe it :)

Also note that this isn't recommended to build in survival as the machine will brewing faster than you can use the potions so a semi-automatic is better suited.
