Black Elder Ale Introduced to Scotland in the 9th century by Welsh Druids, it was part of the Celtic Autumn Festivals when the "elders" made this strong ale and handed over the drink to the people. The recipe comes from a 16th-century record of domestic drinking in the Scottish Highlands. Ebulum consists of roasted oats, barley and wheat, cooked with herbs and then fermented with ripe elderberries. Black beer with brown foam crown. Röstmalzaroma with chocolate notes. The taste is malty, fruity with elderberries. Bitter reverberation, after licorice.
