This is my best-guess clone recipe, based on an email from the head brewer, a statement by their tap room bartender, and specifics which I've read about Founder's other wildly popular Centennial IPA. That said, it still involves a lot of guesswork. I'm working under the assumption it's hopped with Zythos only, which is a Hop Union proprietary blend containing Simcoe, Citra, Amarillo, among others, plus as-yet unreleased proprietary cultivars. This would satisfy the vague statements from the brewer, and Zythos descriptions certainly match the flavours and aromas of All Day IPA. Most homebrewers who have attempted to clone this beer refuse to believe Founders would use only Zythos, and make repeated attempts using various combinations of Simcoe, Citra, Amarillo, Centennial, Cascade, etc, and so far no one has been 100% successful. It doesn't seem far-fetched to me at all, considering Zythos is an IPA blend which works well in all stages, not to mention Founder's other top-seller Centennial IPA uses only Centennial hops at 60 minutes, 20 minutes, 5 minutes and dry-hopped. Many homebrewers also refuse to believe good beer can be made with adjunct unmalted grains, but I'm not even going to dignify that silly snootiness. I haven't personally brewed this recipe yet, but it seems spot on to me. Best of luck!
