Farmhouse has them in stock from 2011. Label peelers has them for preorder and are getting hops in as of Monday (2012 hops). Everywhere I look online I can find Citra so I suggest you do a little more searching and use this very unique hop versus a substitute you won't be 100 percent happy with. I have 2 pounds on the way myself as I love this hop in 3 Floyd's Zombie Dust...
