Pouring Perfect Beer!
You can hold in whatever fashion you want – unlike tea it is fine to ‘spill’.
What this means is you basically check how much yellow is in the bottle and simply keep pouring until it’s ~80% done. Any foam you spill does not matter at all so it’s extremely simple.
As long as ‘beer’ is ~80% – foam is guaranteed to be ~20% regardless of how much went over the glass.
Note: If you have a controller slightly tilting the stick works perfectly. It’s odd how with some things the controller is superior but with others it’s the keyboard.
