On the trail of hard resin components
Analysis of bitter substances | In beer production, the development of modern analyses provides possibilities of extending the analytical spectrum. It is possible to investigate the detailed path of individual compounds from raw materials to the finished beer, using mass spectroscopy. The hard resin fraction of hops that mainly consists of polar i.e. easily water soluble bitter substances is ascribed a special role in terms of dry hopping. This makes efficient transfer of these substances from hops to beer possible. The present contribution describes the compounds involved, as well as the flavour contribution they make to beer bitterness.
