Double IPA

Double IPA, also known as Imperial IPA, is a style that offers a more intense experience than the traditional American IPA. It emerged from the United States' craft beer movement, with roots tracing back to the 1990s. This bolder variant was born out of the desire to push the boundaries of brewing with higher alcohol content and an abundant use of hops. As its presence grew among enthusiasts seeking potent flavor profiles, it has become a staple in the repertoire of craft breweries.

A Double IPA is typically golden to light amber in color; although some examples may be darker. The beer should display good clarity unless dry hopping has contributed some haze. A moderate to large off-white head with good retention is common due to high hop oils and alcohol content. The aroma is unequivocally hop-dominant, showcasing varied notes depending on hop varieties used. When it comes to flavor, expect a harmony between malt backbone and assertive hoppiness; while it's tilted towards hops, there's enough malt richness to support this. Hop flavors are again diverse (fruit-like, piney, spicy) and robust but balanced by a strong yet smooth malt profile with potentially caramel-like or bread-like notes contributing sweetness. Despite the elevated alcohol level (often noticeably higher than standard IPAs), it should not overwhelm the overall balance; instead, it integrates with the clean fermentation profile for a generally dry finish that encourages another sip.

Double IPAs relate closely to their American IPA counterparts but stand out due to their amplified qualities – more significant hop aromas/flavors and higher alcohol content – putting them in league with other "imperial" styles which emphasize intensified characteristics of their base styles.
