Hi gished100, my two penneth...
1. Can I just transfer it into any screwtop bottle once it's fermented?
I use ASDA PET bottles - they're cheap, about 17p per 2 litre bottle and they come with flat water so you can save on your water bills.
2. Should I just use household sugar?
When you make up your kit I would suggest using Malt Extract, which type depends on what your making i.e. light for lager through to dark for porter etc. I use normal sugar to prime the bottles - this amount does not affect the taste.
3. It says that after the fermentation in the warm place and I transfer it to the bottles it then needs to go in a cool place. How cool is that? (My house is pretty warm all over and I don't have a shed)
Personally, I brew the beer at around 21C (for bitter) and as low as possible ~5C this time of year for lager. Then, once it's done my bitter gets transfererred to somewhere a bit cooler 10 - 15C for as long as possible (3 weeks is the max I have been able to leave it alone but longer is better) and my lager gets bottled and put back to around the 5C area (this is called lagering and again the longer the better).
4. How do I tell what alcoholic percentage my lager is? (apart from just guessing by how many it takes to get me drunk

)
You need a hydrometer for this task. They're about £3 in Wilkinsons and are invaluable in determining your alcohol content/fermented sugar content. I use mine like this. Mix the wort but don't add the yeast. Take a sample (you need a trial jar for this, again about £3) fill the trial jar with hydrometer in it and hold up the trial jar so you can see where the wort is against the hydrometer markings - it probably reads something like 1040 - this is your Starting Gravity or Original Gravity. Once fermentation is complete (to find that, take a reading every couple of days to track it's progress, once it's the same over 24 hours it's done). This reading, say, 1010 is your final gravity. Now 1040 (OG) minus 1010 (FG) divided by 7.5 (this takes into account the amount of sugar you will use to carbonate/condition your beer) = 4% ABV.
Sorry for all the questions but I am really wanting to get going and just want to be sure I know exactly what I am doing.
Keep asking and we'll keep answering.
Any help greatly appreciated![/quote]
