Beer brewed after a 13th-century recipe using gruit herbs. Gruit (alternately grut or gruyt) is an old-fashioned herb mixture used for bittering and flavoring beer, popular before the extensive use of hops.

Gruit was a combination of herbs, commonly including sweet gale (Myrica gale), mugwort (Artemisia vulgaris), yarrow (Achillea millefolium), ground ivy (Glechoma hederacea), horehound (Marrubium vulgare), and heather (Calluna vulgaris).
Beer is a word with two meanings. It can mean an alcoholic beverage made from cereal grains, or a non-alcoholic beverage flavored by root extracts. Root beer, birch beer and ginger beer are three common forms of this non-alcoholic sort of beer.he root beer extract is mixed with sugar, yeast and water. If this mixture is placed in a tightly sealed bottle, the yeast will generate carbon dioxide at a high enough pressure to carbonate the water.
