I haven't done a SG check at all and haven't opened it much. I took a quick peek in last night and it looks like there is a ring of scummy stuff at the top of the liquid line
I know this is not exactly the recommended way to brew but have had a really busy patch at work.

What I would like to know and can't seem to find out is how I know the brew has brewed, and if 10 days will have killed the yeast and generally how to proceed with the pressure barrel and secondary fermentation.
I have my dextrose at the ready (1kg) and some more yeast, but wanted to ask you chaps first.
I'll check back after work this afternoon if anyone has replied with sage advice
