When brewing the apple cider I realized that with 2 days aging it's still 5 stars even though it requires 3, why is this? And is there something else that's meant to happen when it is done perfect?

Like what does aging do to the quality?

Apple Cider is a recipe with a rather low difficulty. This means that you don't have to get it perfectly right to get 5 star quality. So a few days more or less aging, a few more or less ingredients and boiling time will not make such a difference.

With for example Absinthe you have to be stricter to make good quality.

You can change this in the config

Tysm, I get it now!
