What to do when your espresso shots are running too fast or too slow.
If your espresso is too quick or too slow, you'll need to change the grind. Once you've changed the grind, you'll have to purge the old grinds out. Every grinder holds some coffee in the chute and burr chamber. Be liberal with the amount of coffee you purge out. Keep in mind, grinds moving through a grinder aren’t ‘first in, first out”. This means that although some of your new grind setting is exiting the chute, there’s still plenty of the previous grind setting left behind. Being liberal with your purging and you’ll end up wasting less coffee in the long run.
