Similar idea, though you went crazy with the lemon! heh, actually my first batch was closer to that, some people really liked it, but I found it a little too tart.
My first batch also used a lot more wheat extract like yours, but I wanted a little lighter color, which is why I scaled up the extra light extract in favor of the wheat. I think my wife liked the darker color a little better, though, so to each his (or her) own! In any case, great stuff Maybe I'll try adding an orange next time like you did, that sounds tasty.
