No idea ...

but here I am on the other side of the hummus thread.* Reed's Extra has 28 g fresh ginger root per 12 oz (355 ml) bottle.

Homemade sounds delicious! but you don't have to make it if the only reason you're doing it is a stronger flavor. It is sweeter though, with 37.4g sugars per bottle.

*At least Reed's comes in recyclable glass bottles.
