• and
• determining a recommended grind size of coffee beans based on the predetermined optimal brew time for a selected beverage and based on a grind size and a brew time for a last beverage formed and dispensed by the beverage machine;
• wherein the beverage machine comprises:
• a grinder configured to grind the coffee beans,
• a user interface configured to receive a user input selecting the beverage for formation and dispensing from the beverage machine,
• a controller, and
• a memory storing instructions that, when executed by the controller, cause the controller to perform the determining.
