The basic purpose of grinding coffee beans is to facilitate the extraction process by exposing more surface area to the hot water. Basically, the process of making coffee happens as roasted coffee beans are brought into contact with hot water that 'extracts' the flavour, ideally resulting in a delicious cup of brew.
Start by setting your grinder to a medium grind setting and then adjust the grind time to achieve the desired consistency. A general guideline is to grind the beans using short pulses, checking the consistency after each pulse. If the grind is too coarse, grind for a few more seconds until the desired consistency is reached.
