Not sure exactly what that means, but our friends over at InventorSpot.com have come up with their list of beers that "push the limits of conventional brewing in a number of ways."

Their list includes a Japanese milk beer (30% milk, 70% beer - sounds, um, interesting), pizza beer brewed with tomatoes, onions, garlic, oregano, and basil (you go ahead, I'll pass), and a beer that is nearly one-quarter alcohol (now we're talking).

According to InventorSpot.com, "these ales definitely have some gusto that the rest of the beer world lacks."

You can read their entire list here.
