There are two widely available forms of hops. Hop flowers or cones are the dried flower of the hop vine. These cones contain resins which impart the refreshing bitterness that we love in our beer. They also contain hop oils which help to give beer that heavenly hop flavour and aroma. Hop flowers have to be boiled with the wort for a period of time and then strained and removed from the boiler. Pelletized hops are pulverized hop cones which can be used without straining. There are also many different varieties of hops which impart unique and distinctive flavours and aromas to your beer.
Hops have three main purposes in brewing. They add bitterness, flavour and aroma. The longer you boil hops the more bitterness you get while shorter boil times will result in more flavour and aroma. Some hops are better suited to bitter your beer while others are best for flavour and aroma. There are also all-purpose hops which you can use at anytime during the boil.
A list of popular hops; there uses, characteristics and possible substitutes.
