An IPA-rooted catch-all for hop-forward beers built on experimental hops, processes, or ingredients that don’t fit the established IPA styles. It keeps an IPA’s hop emphasis and gravity while leaving room for innovation. Broadly 6.3–10.6% ABV with bitterness ranging from moderate to intense.
Origin
The IPA has been the most restless category in modern craft brewing, splintering into West Coast, double, hazy, and other forms as brewers chased new hops and techniques. This category absorbs the leading edge of that experimentation — the hop-driven beers that arrive faster than the framework can name them.
Notes
Where boundary-pushing IPAs land: experimental or newly released hop varieties, unusual dry-hopping or biotransformation techniques, or IPA hybrids that aren’t quite West Coast, hazy, or any other named IPA.
