GDay Oddball,
As everyone has said, keep it simple, follow the instructions on the tin, this will work and youll make beer.
my best advice for you would be, where it says add 1kg of sugar, replace that with a booster kit, Big W sells these, and they are not to expensive. you will get a much better first beer without all the normal biginner problems of no hear on the beer, little flavor and all that.
whar area are you in, find a Home brew club, or even find out if anyone else in near you brews,
A lot af people say be paitant, bugger that, try the beer as its fermenting,as your botteling, and then every week after its been in the bottle, this is a good way to get a feel of how the process works. Im sure like just about all of us you will do that anyway, and im sure that you will think your first beer tastes pretty average. But do yourself a favor and put 6 or 12 beers away someware nice and cool for a few month, then try them, you will be verry surprised'
and above all, ask lots of questions, the net is a wonderfull thing, and there are many well seasoned brewers around, always keed to help.
