I've got a Blichmann Hop Rocket that loves only whole cone hops, which also works really nicely to filter the wort before going in the fermentor. But, I cannot find many varieties of whole cone hops beyond the popular (Citra, Mosaic, etc) ones. Seems like Out Of Stock is a common status despite whatever online or LBS place I visit, and it's been this way for many months. Where did all the whole cone hops go??
