<P> The first documented hop cultivation was in 736, in the Hallertau region of present - day Germany, although the first mention of the use of hops in brewing in that country was 1079 . However, in a will of Pepin the Short, the father of Charlemagne, hop gardens were left to the Cloister of Saint - Denis in 768 . Not until the 13th century did hops begin to start threatening the use of gruit for flavouring . Gruit was used when taxes were levied by the nobility on hops . Whichever was taxed made the brewer then quickly switch to the other . In Britain, hopped beer was first imported from Holland around 1400, yet hops were condemned as late as 1519 as a "wicked and pernicious weed". In 1471, Norwich, England, banned use of the plant in the brewing of ale ("beer" was the name for fermented malt liquors bittered with hops; only in recent times are the words often used as synonyms). </P> <P> In Germany, using hops was also a religious and political choice in the early 16th century . There was no tax on hops to be paid to the Catholic church, unlike on gruit . For this reason the Protestants preferred hopped beer . </P> <P> Hops used in England were imported from France, Holland and Germany with import duty paid for those; it was not until 1524 that hops were first grown in the southeast of England (Kent) when they were introduced as an agricultural crop by Dutch farmers . Therefore, in the hop industry there are many words which originally were Dutch words (see oast house). Hops were then grown as far north as Aberdeen, near breweries for convenience of infrastructure . </P> <P> According to Thomas Tusser's 1557 Five Hundred Points of Good Husbandry: </P>
