Growing your own barley?

Seems reasonable. It doesn't seem to take the farmers around here a lot of effort! I have seen Barley grown in Japan "manually" (i.e. very small fields, probably rotated with Rice) in rows some considerable distance apart, and it seemed to produce massively tillered plants. I can't remember the yields they talked about, but I do remember the figures being impressive. They get lots of rain in the Summer, and heat, in Japan so that may have had more to do with their yields.

I think Wheat will get up to about 4 tonnes per acre yield, Barley less so.  But if I have calculated it correctly 4 tonnes / acre is 1kg / sq.M ... don't know how much you need for brewing, but seems that not too much land would be needed.

Malting should just be a question of flooding a container of Barley with water for a while, draining off, turning (to stop any roots matting), and "drying" when the growing tip is about 2/3rds the way along the seed.  Drying in the oven perhaps?  I expect you would need to Roast the malt if you want to make a Stout

Or can you brew the malt without drying? just go straight to the mash stage perhpas?
