Hi Chuggalug,
Im no expert, but I am happy to give some advise.
1. Be clean, but no need to wash things with Domestos (dont worry, i've seen this!)
2. Start with a basic Tin / Brew Enhancer (thats the fementable contentent - sugar / malt) and yeast (the ones that come with the tins are fine)
3. After you have done a couple of these and have a handle on temp / brew time / etc, move on to adding hop bags / hops / malts / etc (you will find all sorts of recipes and advise on this sight - its awsome!)
4. You will soon make beer as good, most probably better, that Calson Dry very quickly!
5. A Canadian Blonde would be a good place to start and will produce a light flavoured easy drinking beer
Good Luck
