Well Despite all of the problems I have had, I've now tried my first beer and all I can happily say it is a success :D
I say it is a success, it looks and tastes great.
In preparation for my next brew, I have ensured I have more stuff. I have bought a hydrometer and an airlock (I was advised against both of these when buying new kit).
Question 1: Will the hydrometer give me the approx alcohol content of my finished beer (I did try and this showed to be about 2%)?
Question 2: The airlock had a little plastic cap which I have appeared to have lost. Is this needed?
Thanks for all the previous help and advise in allowing me to achieve a beer I can enjoy. Pleased with my first result and hoping my next is even better.... Even if the alcohol content is a lot lower than I hoped for I am still enjoying it. Guess it just means I can drink more and not get drunk!!!
