Spectrophotometric studies on the is ooctane extracts obtained in various common methods for determining bitterness revealed that an ale brewed in 1875 now contains an unusually large proportion of materials other than iso humulones. A similar result obtained for modern ales maintained for short periods at elevated temperatures in contact with air suggests that these “background” materials may have been formed from is ohumulones by oxidation. Other constituents in the old ale are consistent with its high original gravity and its age.
