Hi there Lucas!
As the blokes/girls mentioned above, sanitation and temperature are the real keys to your first home brew. The sanitation you have to do anyway, there's no way around that but it's easy. See
here for all the info you need on that for now.
One further note re sanitation, buy a 60 litre square tub from Bunnings at $16 and fill it with the bleach ratio mentioned in the above link. This will handle all your big equip. Also get a smaller container, mayber 10 litre for the betadine. Above thread will explain all that.
Temperature! I totally agree with Screwtop. I brewed several crap beers about 15 years ago simply through following kit suggestions. If someone had told me then, brew your kit beers at a stable temp of 18-20 degrees, I would have never looked back! But, I gave up after 2 brews. Any beer in the bottle or on tap was 100 times better! The same thing happened about 8 years later! Thanks to this site though, things have changed.
In my opinion, unless you live in a perfect climate or have a house where there is a room that is stable at 18-20 degrees for at least 4 days, you are not going to brew a reasonable beer using just a Coopers or Tooheys Homebrew Kit.
So, I would suggest, before even your first brew, you buy a 100 Can Cooler (post #8 of this
thread will show you a picture. You can get them at KMart for $20 or $30.
You will also need, depending on your climate, say 8 x 1.25 litre soft drink bottles filled with frozen salty water. It's really hot where I am so I have 12 x 750ml freezer blocks.
If you can invest that $20 or $30 you will be well-rewarded. At the moment, I think that and sanitation are the only things you need to worry about. Stick with the Coopers for the moment as they are the most forgiving and quickest to drink!
Sometimes reading on this site can get a little confusing so after you have the above right, maybe learn a little about hops.
Oh, and I forgot to mention that you will need to use the blow-off tube method of air-locking if you have the 100 Can Cooler as an air lock is too high. Anyway, don't worry too much about that now though you may need more soft drink bottles. If you do a search for blow off tubes thouvh you'll get the info!
Cheers Lucas :beer:
Edit: Forgot to say, that if you follow the above, you will find the Coopers/Tooheys great! Then, with time things will get even better!
