Notes

Used 7 slices of toasted and roughly torn crusts.
Pre-boil gravity at 1.061. This is perfect as I aim to water back when putting into the fermentor.
3 litres cold tap water added to the fermentor OG allowing for temperaure 1.061. Bang on...pretty much.
Sample temp was originally 70c, so below isomerisation temps too
Very warm days in the UK. Pitched at 19c but soon temperature rising to 22c for high Krausen and then following day upto 24c even touching 25c.
So, I am expecting fusels which means a long conditioning time. Hey ho. Can't be helped. But temps steady at 24c for most of fermentation which is not so bad. Sample on day 8 is 1.013 which one beyond target. Sample again on day 11 and if there's no movement time to bottle. Sample smells amazing.
1.012 on Day15. Definitely ready.
1 year on and this is perfect. Lovely deep flavour. No detectable fusels now. Only problem is because the storage hasn't always been cool it has become a gusher. Apart from that no complaints.
