As an expert sommelier and brewer, I can shed some light on the difference between a double IPA and an Imperial IPA. To put it simply, they are essentially the same thing, just with different names. Both terms refer to an IPA that has been taken to the next level in terms of intensity and flavor.
The origin of the name “Double IPA” is often attributed to the extra “I” in the abbreviation of Imperial IPA (IIPA). The term “Imperial” is commonly used in the beer world to denote a beer that has a big, bold flavor profile and a higher alcohol content. So, when you see either “Double IPA” or “Imperial IPA” on a beer label, you can expect a beer that is packed with hoppy goodness and has a higher alcohol content compared to a regular IPA.
In terms of flavors and characteristics, both double IPAs and Imperial IPAs are known for their intense hop aroma and bitterness. They typically feature a robust malt backbone to balance out the hoppy flavors and provide a sturdy base for the higher alcohol content. The hop flavors can range from citrusy and piney to floral and resinous, and the bitterness can be quite pronounced.
When it comes to personal experiences, I have had the pleasure of tasting and brewing both double IPAs and Imperial IPAs. The brewing process for these beers often involves using a generous amount of hops during the brewing process, including multiple hop additions during the boil and dry-hopping techniques to enhance the hop aromas. The result is a beer that is bursting with hop flavors and aromas, making it a delight for hopheads.
It's worth noting that the terminology surrounding beer styles can sometimes vary, and different breweries may use different names for their high-ABV, hop-forward beers. Some breweries may use terms like “Triple IPA” or “Extra IPA” to describe beers that fall into the same category as double IPAs and Imperial IPAs.
The difference between a double IPA and an Imperial IPA is essentially just the name. Both terms refer to an IPA that has been turned up to eleven in terms of hop intensity, flavor, and alcohol content. So, if you're a fan of hoppy beers and are looking for a bold and flavorful experience, give these beers a try!
