I gave the bottles a squeeze and they're nice and firm, so I decided to open the first bottle i took from the fv (this have some small lumps floating when I did this so have it marked as a tester/throwaway). It has a bit of fizz, not loads but enough, was still a bit cloudy (from where I stupidly shook them up last week) and still had that homebrew taste about it (but it's only been 3 weeks since I started the brew). All in all I'm pleased with how it's progressing. The plan is to leave it in the warm box till Wednesday, at which point I will be bottling my Canadian blonde, then move it onto a shelf in the garage to clear up for a few weeks.
I'll probably crack open my second tester next weekend once it's had a couple of days resting in the cold. I'll update you all which it then.
