It's really easy to find hops that aren't predominately grapefruit. Cascade, Chinook, Centennial, Summit, Amarillo, CTZ, and Simcoe can all possess grapefruit elements of varying strengths. You have a lot of other options to go with if you avoid these hops. For APAs and IPAs, you could test the New Zealand varieties. They're fruity, tropical, and grassy at the same time. A sort of blend between the newer American hops and the proven Noble hops.
