Since 2013, craft brewers with an interest in making gruit ales have banded together to mark February 1 as International Gruit Day. The day is intended to pay homage to the historical traditions of brewing with botanicals.

What is Gruit?

Gruit (alternately grut or gruyt) is a herb mixture used for bittering and flavouring beer, popular before the extensive use of hops. Gruit or grut ale may also refer to the beverage produced using gruit.
