What is a hopback used for?

A hopback is specifically designed to run hot wort through a chamber filled with hops. During this process, the hopback allows the contact between the hot liquid and the hops, which infuses the wort with hop aromas and flavors without extracting excessive bitterness. This technique is particularly useful for brewers aiming to enhance the aromatic qualities of the hops in their beer, especially in styles where hop character is a critical component, like IPAs.

This method contrasts with other aspects of the brewing process. For instance, extracting maximum bitterness from hops typically occurs during the boil, where hops are added and their alpha acids are utilized. Similarly, dry hopping during fermentation involves adding hops after the boil, focusing on aroma rather than bitterness. Lastly, filtering the wort before fermentation is a separate step aimed at clarity and preventing unwanted particles from influencing the final product, rather than enhancing hop characteristics. By running hot wort through a hopback, brewers can directly impart fresh hop character to the wort in a way that complements other boiling and dry hopping stages.
