Overall similarity
hopIQ take
Rhinegeist Knowledge DIPA if you want bold citrus punch and clean finish,
Second Fiddle if you want juicy, layered complexity.
Both hit 80 IBUs but land totally differently—Knowledge is direct aggression, Second Fiddle is a conversation. That extra 0.8% ABV on Knowledge matters less than the breweries' philosophies: Rhinegeist leans into sharp, Fiddlehead into texture.

Tasting notes
Rhinegeist Knowledge DIPA
Knowledge doesn't mess around. You get immediate grapefruit and pine on the nose, then a crisp resin bite that cuts through clean. There's a slight boozy warmth at 9% but it doesn't linger—the finish is dry, almost mineral. It's a beer that tastes like someone had a clear vision and executed it.
Second Fiddle Double IPA
Second Fiddle opens softer, almost creamy despite the same IBU count. Orange zest and peach sit under a subtle herbal layer that makes you want another sip to figure it out. The mouthfeel is rounder, less aggressive. At 8.2%, it drinks lighter but feels more substantial—there's actually something to chew on here.
