Brewers Garder Specialty Herbs and Spices. Also called Bog Myrtle and Badge of the Campbells, Sweet Gale is a deciduous shrub with fragrant wood and leaves found abundantly in the Northern Hemisphere especially in the Scottish moors and bogs. It has been used as a substitute for hops in Yorkshire in a beer named appropriately Gale Beer. The seeds and leaves have also been used in soups and stews, perfumes and candles. This is not surprisingly since it is in the same family as bayberry, which is a popular candle scent. Used as a tea infusion it has been known to ease stomach disorders. This relatively unknown herb is well suited for Holiday beers.
