Farber's recipe says 20%, I'm not sure about the recipe on Eric's site. I have no idea how you can test it either, a hydrometer maybe? Of course a lower dilution can easily be made to whatever percentage you want providing you know the original strength using the criss-cross method.

I totally agree. I've decided that when I need FO I'm gonna buy the dry version.
