 The brewing process for beer is the same as for ale, but we reserve the 
word  beer  for a brewing process that uses hops for fl avor and preservation. 
Hops is a climbing vine that grows male and female fl owers; the female 
fl owers are used as a fl avoring in cooking. In Roman times, they were used 
as seasoning. During the time of Charlemagne, hops were grown in  gar-
dens,  and they may have been used for fl avoring ale, like any other herb. 
The growth and trade in hops increased during the Middle Ages, and it 
was often grown in monastery gardens. In the 9th century, some Frank-
ish bishops wrote about the use of hops in brewing ale. However, its use 
remained local and undifferentiated from other herbs until the 12th cen-
tury. When used in brewing, the hops were added to the boiling wort in 
a bag so they could be removed cleanly. If not, they had to be fi ltered out 
with any other vegetable matter. 
 Hopped beer did not spoil as readily, as the hops prevented the growth of 
bacteria. Hopped beer could be more widely sold and imported out of its 
region, unlike other ales, which had to be quickly consumed locally. Hopped 
beer could be made with lower alcohol content, so it could be made in 
greater quantity and more cheaply. However, its taste was dramatically dif-
ferent from traditional ale fl avored with bog myrtle or rosemary. Consum-
ers did not immediately take to it. Beer was most often made from barley, 
like traditional ale, but it could also be made from oats, wheat, or rye. The 
taste of different beers began to vary widely, since each grain made a differ-
ent taste, and other herbs such as mint were still added with the hops. Each 
brewery guarded its recipe. 
 Hopped beer became a big export from northern Germany after 1200. 
The Hanseatic League, centered in Hamburg, began to ship both beer 
and hops. Since the Hanseatic League already had a marketing network 
for herring and codfi sh, it was easy for them to incorporate international 
beer sales. Beer from Bremen, Hamburg, and Wismar sold well in the mar-
kets of Flanders and Holland. Hopped beer was also a boon to sailors on 
 ships,  since it would not spoil during a voyage. As consumers adjusted 
to its taste, beer was in more demand than traditional ale, and brewers in 
Holland began to make hopped beer. 
 In a city of reasonable size, there might be over 100 small brewers. 
A large amount of the harvested grain went to beer, since water was not 
safe to drink. Even as the population of Northern Europe fell during the 
14th century, the import of grain increased because beer became more 
popular. 
 Beer was always considered inferior to wine, but it was less expensive, 
and it became the most common drink outside the major wine-growing 
regions of France. Some considered it a healthful beverage, and some did 
not. The Black Death  plague  also helped beer catch on. Fewer people
