Talking with some hop growers in NC, they said the yield is lower there than MI, about 25% of Yakima. They become very competitive for the fresh hops, as they do not have the express shipping charges.
I know a guy who has 1/4 to 1/2 acre of hops. All of those go to Arcadia for a fresh hop beer.
If you are in Grand Rapids go to Siciliano's, they sell some MI hops packaged for the homebrewer.
