I dry hop in kegs. I use a mesh bag that I soak in starsan for a few mins, then dip my hands in to get the bag out. I just throw the hops from the bag I store them in into the mesh bag and chuck that into the keg. I have never had an infection doing things this way.
Hops are naturally anti-bacterial. Legend goes they were originally added to beer because of this property. You don't need to do anything to the hops, just sanitize anything else that will be going into the beer.
The power to tax, once conceded, has no limits; it contains until it destroys. I was not joking when I told them to dig into their own pouches. It may not be possible to do away with government sometimes I think that government is an inescapable disease of human beings. But it may be possible to keep it small and starved and inoffensive and can you think of a better way than by requiring the governors themselves to pay the costs of their antisocial hobby?
