What is hop back?
Hop back is a brewing vat into which the wort is run after boiling in the kettle tank and
which has a perforated false bottom for straining off the hops. It is also called hop jack.
The hop back is normally positioned between the brew kettle and heat exchanger.
What is the function of hop back?
Hop backs provide flavor and aroma without adding significant bitterness to the beer.
Adding a hop back are a great way to improve the flavor and character of your brews.
We recommend putting your hops in perforated false bottom to keep them in the hop back and out of your wort heat exchanger.
How is the hop back operation?
Hot wort passes through the hop back. As the wort does not spend much time in contact with the hops,
bitterness is not extracted (much) but the flavor and aroma of the hops are imparted to the wort.
The amount of bitterness extraction depends on the level of bitterness that already exists in the wort.
The lower the IBUs of the wort coming out of the brew kettle, the more bitterness will be extracted in the hop back.
In any case, it is much less than you will see by adding hops to the kettle.
