If I averaged 2 5-gallon brewdays per month and those brews used an average of 3 oz of hops, I would need 72 oz of hops per year. Assuming each rhizome produced 1.5 lbs of hops (dried), I'd need only three rhizomes for my hobby. Of course, I'd want more than three varieties.
How many rhizomes do you have, and is it enough to quench your brewing thirst?
