Why do I have to use more coffee than normal
Fresh coffee has more CO2 in the bean than a bag sitting on the shelf for a few months. CO2 in the bean enables more bloom (expanding) during the brew and is not the same as if it were stale (lack of CO2).
Koffee Kult beans are fresh and will have a larger bloom do to the increased CO2 that will help extract more of the taste (minerals and fats) while brewing. For example fresh beans used for espresso will have more crema from having more CO2 and extracting all of the coffee. If you would like to use the same dosage as other coffees you may want to let your Koffee Kult beans sit for in the cabinet longer or adjust your grind.
