Robbo,
congratulations on making your first beer! Now that you have gotten started in this addictive hobby, it's time to have a crack at a quality brew. If you're game, try this simple recipe.
Go to the homebrew shop and get yourself a good quality kit (Morgans Blue Mountain, Morgans Amber, Coopers Draught, etc), 1kg Liquid malt extract (LME), 250g medium crystal malt grains (ask the HBS guy to crack it for you), 15g hop pellets (say goldings or tettnanger variety), a nylon grain steeping bag, and a packet of Safale dry yeast.
Put 4L water in a pot and bring to the boil. Put your grains in the steeping bag, tie it in a knot and throw it in the pot. Bring back to the boil for 10 mins. Take the bag out (do NOT squeeze the grains!) and sit it in a colander over the pot. Pour some hot water from a keettle over the grains to rinse out the sugars. Into the pot, pour in your LME, bring to the boil for 10 mins. Next, pour in your can of kit wort and dissolve well. Put the lid on the pot and put the pot in a bath of cold water for 10 mins. Keep replacing the cold water until the wort is cool (under 30C is good). Pour the wort into your fermenter, aerate heavily (i.e turn it into a pile of foam!), top up to 23L then aerate heavily again. Add your Safale and ferment as usual for 1 week. After 1 week, put your 15g hop pellets into a coffee mug and pour in just boiled water to fill the mug. Let sit for 2 minutes, then pour into your fermenter (if you rack to secondary, pour into your secondary fermenter before racking) and do not stir. Let sit for 1 week in primary or 2 weeks in secondary. Prime and bottle as usual and drink after 3 weeks.
This should give you a nice English/Irish style amber ale. Enjoy!
