It is "proprietary" information that only the brewers at Mr Beer know I believe. That being said, the Whispering Wheat has almost no hops typical to a wheat beer. I personally wouldn't mix the two, but that is just me. I also got started with a Mr Beer and really like the Whispering Wheat if you add a lb of wheat DME and use a wheat yeast, I use Danstar Munich. If you do decide to combine them, report back because I'm curious how that one turns out!
