Overall similarity
hopIQ take
Rhinegeist Knowledge DIPA if you want bold, resinous aggression,
Second Fiddle if you want balance and drinkability.
Both clock in at identical IBU 80, but Knowledge hits harder at 9% ABV—you'll feel that extra muscle. Second Fiddle's slightly lower proof (8.2%) lets the malt structure breathe without getting steamrolled by hops. Pick based on your tolerance for intensity, not just the style name.

Tasting notes
Rhinegeist Knowledge DIPA
Knowledge is a full-contact double IPA that doesn't apologize. The first sip slaps you with pine resin and a bone-dry finish that lingers like sticky sap on your palate. There's a subtle caramel backbone underneath, but it's fighting for air—the hops win decisively. At 9%, there's a warmth that creeps in on the second glass, making this feel like an endurance test you actually want to take.
Second Fiddle Double IPA
Second Fiddle is the more elegant sibling—citrus-forward with a cleaner hop profile that feels refined instead of raw. The malt sweetness comes through enough to cushion the bitterness, so you're not left chasing water after each sip. It's got structure and complexity without wearing you out. Drinks more like a really good IPA that happens to be doubled up.
