Coffees from Kenya are usually very fruity / acid of two reasons. Variety and terroir. 

When calibrating your espresso shot, make sure you bring out a medium to high acidity. A shorter extraction time is recommended. The coffee beans are also bigger than a ie. a bourbon variety -´ and sometimes they have a tendency to jump in the grinder during the grinding process depending on your grinder. 

- so make sure your grinder is filled with a little bit more than usual. I always recommend as little as possible. But in this case, you want to maintain a homogeneous gravity when the beans get in contact with your burrs.
