For the ingredients that would make a 5 galloon of beer, we will need one can of malt extract (pre-hopped), one kilo of fine sugar (preferable the one that is known as dextrose or corn sugar), one sachet of yeast and water (tap water will do but if it doesn't taste good you may opt for filtered water). The usual half keg that you can use can carry as much as 15 gallons of the alcoholic drink which in turn translates to 6 cases of beer. Now, think about the convenience that this will bring you every time you host a party in your home. No more running for another case of beer, right? And the presence of this system is important since beer needs to be kept cold, and the keg surely does the job well. Fermenter While the brew ferments, it has to be free from contaminants such as dust and airborne microorganisms. An airlock fermenter, therefore, is needed. For the majority of home brewers, a good carboy, typically a glass bottle that holds 5 to 6 gallons of brew, will do. A high quality plastic bucket is also not an uncommon choice among serious brewers. Now use this with caution since the bitter or burnt flavor can be quite strong if used with liberty. As a rule, make use of these grains with caution. The chocolate malt. This grain is similar malt and the only difference lies in the fact that this grain isn't processed that long. And as such, this doesn't carry the usual burnt flavor associated with the black malt. You don't want to use bottles that are cracked and chipped. Clean and maintain the bottles with the use of ammonia. This is especially true if you are using old bottles with labels. The old bottles for use in bottling the brew should be soaked in a mixture of water and ammonia. After that, just rub off the labels to clean it up. You could locate this argument on how beers developed and enhanced. This means that man being the rational animal through its gifts of creativity was able to cope with change and allow history to take place and continue its journey. Let me simplify it. The history of brewing is also the history of evolution.
