I want to know the answer to the following question:
In which century did hops become the most popular flavoring for beer?
All the background I'm provided with is that "The first historical mention of the use of hops in beer was from 822 AD in monastery rules written by Adalhard the Elder, also known as Adalard of Corbie, though the date normally given for widespread cultivation of hops for use in beer is the thirteenth century.". Is that enough to answer the question?
Answer: no
