I went out today and checked again. Bean blossums and a few pods, quite a few more than meets the eye the foilage is so thick, but lots of pods aren't mature, so if it doesn't come a kill frost, i'll be getting a few, but next yr I think i'll plant earlier and on an east and west trellis instead of a tee pee.
As to the sorghum, if johnson grass will grow where you live, it might be possible to raise sorghum. If it doesn't head, the sugar content will be a lot less, but that's easy enough to tell by cutting off a piece and knawing on it.
If processed too early, it may contain more starch than sugar, but malt will convert it. We do that just to make sure, and it only takes the seeds about a day to sprout so it can be had in a hurry.

Lot of varieties are a lot shorter and take a shorter growing period.
I think I read somewhere they have varities that grow well in Minnesota which is pretty far north of here.
As far as syrup to juice ratio, its about 6:1. Mayple syrup is 40:1, so we're doing sorghum. It's been interesting, and goes good with the beans
