as predicted by a few on here I may be okay and indeed after getting a hydrometer and checking tonight (6 days on) I am down to 1.016 on my Admirals reserve and the initial vigourous froth has now given way to a gentle bubbling all over the surface, the smell is quite pleasant, in fact not too disimilar to the brewery just down the road at M4 junction 11

So fingers crossed I'll keep checking every couple of days and see when it stops bubbling / stabilises and see what I get down to on the hydrometer.... temp seems a very stable 20 degrees in the cupboard on the stairs....
Dont know how Im gonna wait for it to fully mature though

Cheers (a very relieved) Steve
