Beer's Bitter - The absolute configurations of the bitter acids of hops determined

Latest News

Beer's Bitter

The absolute configurations of the bitter acids of hops determined.
During brewing, beer obtains its bitter flavor from the bitter acids that come from hops. In the journal Angewandte Chemie, scientists now report that they have used X-ray crystallography to determine the absolute configurations of these humulones and isohumulones, as well as several of their derivatives.
