A Double IPA, or Double India Pale Ale, is a style of beer known for its strong hop flavor and higher alcohol content, typically ranging from 7.5% to 10% ABV. This style originated from the India Pale Ale category, which was originally brewed to withstand long sea voyages. Double IPAs often feature a bold, hoppy aroma and a rich, malty backbone to balance the bitterness. Brewers achieve the intense hop profile in Double IPAs by using a larger quantity of hops during the brewing process, including both bittering and aroma hops. Common hop varieties include Citra, Simcoe, and Mosaic, which contribute fruity and floral notes. The result is a complex and flavorful beer that appeals to hop enthusiasts.
