Interesting. Here's some quotes taken from that site:
BriesSweet Brown Rice 45 High Maltose can be used for 100% extract brewing to produce rice beer (sake) or use it with concentrated worts to produce almost any beer style.
As a grain-based syrup, it provides proteins and amino acids necessary for yeast nutrition, head retention and body along with color and flavor
Gluten free, hypo allergenic, non-GMO
BriesSweet Brown Rice Syrup 45DE High Maltose can be used for 100% extract brewing to produce rice beer
Use it with concentrated worts to produce almost any beer style.
And at 3 bucks a pound, that isn't all that bad. It makes me wonder what the difference between this and the brown rice syrup I can get at the grocery store is.
I may have to try to make sake...
