@fredley regularly brewed coffee. Filter the grounds vs. putting the ground coffee directly in the water. Does this change the amount of caffeine in the coffee?

"Regularly brewed coffee" can be very different things for different people (not least those in Bali)! Are you referring to something like one of [these](https://i.sstatic.net/bQyGV.jpg)?

Bali coffee is made by tossing finely ground coffee directly in the water (no filters, etc.).

Does this change the amount of caffeine in the coffee, compared to coffee from a filter machine?
