Krieg und Friedena Kräuterlikör 1937 T-Shirt

Krieg und Friedena (war and peace) brand Kräuterlikör was first produced in 1937 and quickly became a popular brand both at home in Germany and abroad. Kräuterlikör is an herbal or spiced liqueur, also known as "half-bitters" that is traditionally served neat as a digestif. In contrast to bitters, they have a higher sugar content, expressed as invert sugar, and typically contain 15% to 44% alcohol by volume. Mixtures of alcohol and bitter substances were used as medicine to increase bile and gastric acid secretion; however, the higher proportion of alcohol and sugar is not conducive to digestion. Nowadays, Kräuterlikör is also served as an ingredient of different cocktails and long drinks, though Kräuterlikör dates back to the Middle Ages.
