This event is fired immediately after a potion has been "brewed" by the brewing stand tile entity, when the output items have already been replaced. If the PotionBrewPreEvent has been cancelled but the itemstacks within the brewing stand have been modified, this event will also be fired.

If the pre-event is cancelled without modifying itemstacks, this event will not be fired.

You will need to cast the event in the function header as this class:
crafttweaker.event.PotionBrewPostEvent You can, of course, also import the class before and use that name then.

PotionBrewPost Events implement the following interfaces and are able to call all of their methods/getters/setters as well:

• IPotionBrewEvent

The following information can be retrieved/set during the event:

ZenGetter	ZenSetter	Type
ZenGetter length	ZenSetter ​	Type int

ZenMethods

• event.getItem(int) returns IItemStack on the given index in the crafting station. Will return an empty IItemStack if the specified index is greater than length.
• event.setItem(int, IItemStack) Replaces or sets IItemStack on given index. If the index is greater than the length of the item array, nothing will happen.
