The brut IPA borrows its name from the wine world; in champagne, brut means very dry. So too with the brut IPA. The trend has only been in existence for about a year or so—too short in beer time to coalesce into a defined “style”—but it has a few hallmarks. It’s pale, it’s bone dry, it’s highly effervescent. In short, it’s as close to champagne as an IPA can get.
