<human>: What is the best type of coffee for my machine?
<bot>: The best type of coffee for your machine will depend on its make and model. Generally, dark roast coffees tend to work better than lighter roasts as they can provide a more intense flavor. Additionally, some machines may require certain grind sizes or brew times in order to produce the optimal cup of coffee. It's recommended that you consult your machine's user manual to determine the right type of coffee for it.
