Interesting data. This is the 2012 USDA report that shows how many acres of each hop were planted compared to last year. Now remember, these are potential yields, and they don't account for what the growing conditions will be like this summer.
They planted over twice as much Simcoe and Citra. Amarillo got lumped into 'Other' so it's tough to tell if they are growing any more of it.
Kind cool data though.
