TRUE GRUIT HERBS: Gruit ale is historically linked with these 3 herbs. Delicious and satifying beers can be brewed from either of these on their own, but a true gruit will usually contains all three.
SWEET GALE aka BOG MYRTLE
About: Sweet gale (or Bog myrtle) was the most prominent ingredient of medieval gruit. It's a small, deciduous shrub with resinous-tasting leaves. It gives the brew a slight retsina-like taste and a resiny, eucalyptus aroma.
YARROW
About: Yarrow has probably been one of the most widely used herbs in the world. It grows in profusion wherever it takes root. Yarrow has bitter, astringent-tasting leaves and flowers. Today, it is grown and known mostly as an ornamental garden plant.
MARCH ROSEMARY aka WILD ROSEMARY
About: Wild rosemary is used in beer for it's pleasantly fresh and spicy aroma, its bitter taste and also its narcotic properties. Traditional beer recipes specifically call for fresh flowering tops.
