Saw this at mybeerbuzz.blogspot.com and also on Stone’s website. An unfiltered IPA will be the latest from the Enjoy By Series. Iowa is on the list of markets to receive it. Here is more from Stone’s website:

In most cases, skipping a step is a bad thing. Not this time. This version of Stone Enjoy By IPA omits the part where we filter out the extra yeast, hop sediment and proteins that build up in beer as a natural result of the brewing process. Though it may sound like it, this missed step was no misstep. By letting this IPA go unfiltered, its peach and tropical fruit hop flavors are amplified while its golden-hued color takes on a hazy appearance. Like its filtered counterpart, this IPA is brewed specifically NOT to last, and is shipped immediately to ensure hopheads get their hands on it as soon as possible.
