I'm in Philly. I have 3 varieties, Mt Hood, Magnum and Golding. next year will be their 5th season, with each year producing a bigger and bigger harvest and more and more bines. the mt hood and the magnum are my best producers. if I could do it all over again, I would NOT have planted the Magnums. They are really only useful as a bittering hop and I have no clue what AA they are. To be honest, if I did it all over again, I'd only grow the Goldings. they produce the least return but the hops themselves are outstanding.
