I am surprised by the cost comparison.
That argument is from people who spend far too much time fertilising them etc.
They are weeds and need only water and sun and the latter isn't all that important (mine dont get sun until early afternoon, one not until after 3pm). I have rainwater so water costs nothing but the electricity to pump it to the garden.
I get well in excess of 1kg per year dry now from 5 plants, more than i use. The only thing they get is water and an annual dose of horse poo (free from inlaws neighbours, i do have to shovel it myself)
Pelletised hops aren't a patch on fresh hop flowers. I pack mine into 100g lots (vac packed so yes, you'll need one of those but i use ot for all sorts of foods as well) and when i use a bag the empty bag spends weeks in my brewery so that i can sniff it every time i walk by. It reaks of gorgeous hop aroma for weeks. Pelletised hops don't do this, they turn dusty in days.
It requires patience though. It took me until the 3rd season to get a sufficient crop but i an now technically self sufficient and to the OP, i only drink as much as you.
I am biased though. I don't brew all that often so when i do i go for a tried and true recipe - my golden ale using which homegrown hop i feel like.
When you can buy the best hop (Victoria) I may give up hop growing but until then my Victoria rye golden ale can't be made by any commercial brewer. Only me
And that is why i brew :chug:
