I live in Washington state in the us, and there is a lot of hop growing on the eastern side of the state. They offer a hop class for home brewers, and I took it several years ago. They said that high alpha acid hops like you’d use in IPAs require a specific climate (sunlight and heat) to get the bittering levels up and recommended us home brewers only go for the aroma hops when growing at home. I’ve grown, and continue to grow willamette, cascade, tettnang, and sterling. I’d have to look, but I’m pretty sure the willamette are the best producers for me.
