BREWING NOTES:  Smooth 3 hour brew day. OG slightly under. Maintaining mash temp on the stove worked really well. The calculator is really dialled in now. Chilled to 50°C @ 1100hrs. Yeast pitched 8 hours later at 23°C with airlock activity the following day. Fermented in the loft due to the temperature issues with the last batch. Secondary fermentation in keg. Accidentally bubbled some air through when transferring to dry hop keg. Kegged on 10/11/24 and placed at 19°C. Transferred to the 9 litre keg on 13/11/24 leaving around 650ml in the dry hop keg.
