White IPA is an IPA brewed with added wheat. The wheat adds a haze to the beer’s appearance and fruity and spicy notes to its taste and aroma. The flavour of white IPA is slightly smoother and less bitter than that of American IPA.
White IPA can be described as a mixture of IPA and Belgian witbier.
It was only a matter of time before craft brewers experimenting with IPA ingredients reached wheat malt. No one knows for sure when and where it was first used, but the first official mention dates to 2010 in the USA. Wheat malt was added to American IPA, resulting in a blend of wheat beer and "regular" IPA.
It became an official IPA type in 2015.
