Nice post and sounds like it'll be an interesting beer. However, I completely disagree with your comment in your post about frozen fruit not needing to be sanitized. While freezing can kill certain bacteria, there's quite a few (bacteria) and yeast (including wild yeast) that can survive freezing/thawing just fine. In fact, yeast cultures are often frozen for long term storage. I had a wild yeast take hold in a peach and apricot wheat beer once. I'd washed the fruit, cut it, then froze it before racking onto it in secondary. Now I always treat fruit with potassium metabisulfite and since doing so I haven't run into any issues. I'm not saying you will have an infection, but freezing is not a substitution for sanitizing.
