BREWING NOTES:  Whole volume to the fermenter, no siphon. Calculator figures for volumes were 100% accurate. Maintaining mash temp on the hob isn’t as even as I thought due to it getting hotter in the centre. I’ll probably stick with it though with a stir at 30 minutes. Agitating the hop spider meant that the bulk of the hops escaped into the kettle and ended up in the fermenter. OG was 4 points higher than predicted which puts the efficiency up to 67%.
