I want to know the answer to the following question:
In breweries, what do you call a small vat that is filled with hops?
All the background I'm provided with is that "In some breweries, the hopped wort may pass through a hopback, which is a small vat filled with hops, to add aromatic hop flavouring and to act as a filter; but usually the hopped wort is simply cooled for the fermenter, where the yeast is added.". Is that enough to answer the question?
Answer: yes
