I want to know the answer to the following question:
In what century did the habit arise of pubs selling beer from only one brewery?
All the background I'm provided with is that "The usual arrangement for a tied house was that the pub was owned by the brewery but rented out to a private individual (landlord) who ran it as a separate business (even though contracted to buy the beer from the brewery).". Is that enough to answer the question?
Answer: no
