Dogfish Head 90 Minute IPA is a well-known American India Pale Ale from Delaware, famous for its unique brewing method. The name refers to the continuous hopping over 90 minutes during the boiling process, resulting in a very balanced ratio between intense bitterness and malty sweetness. The beer has a higher alcohol content (around 9%) and offers complex aromas of caramel, citrus fruits, and resinous hop notes. Despite its strength, it feels surprisingly smooth and harmonious and is considered a classic of the American craft beer scene.
