RIPA into Kegs

First attempt at both CO2 capture and kegging. I sanitized and purged kegs during first few days of active fermentation then used closed transfer system to empty sanitiser. This left kegs oxygen free and sanitised ready to receive beer. I left pressure at 3-4 psi for 5 days and dry hopped at day 5 using the hop bomb on top of fermzilla. By this stage fermentation had slowed right down and when I screwed spunding valve tight shut, pressure only went to 16.7 psi at 22C. I increased temperature from an initial 19C for 5 days to 22C for 3 days to clean up any sugars. From day 8 to 14 I decreased temperature to 4C where pressure settled at 8.3 psi. This equated to 2.1 volumes CO2 and once kegged, produces a nice head and mouthfeel. The main issue with this brew was the very large whirlpool addition meant transfer from kettle to fermenter was problematic. I think I left at least 2 litres in kettle as hop cake was blocking everything. Hence only 19.6 litres in keg. Need to look at a hop spider/bag or use cryo hops to reduce volume. Brew came out at 6% abv and has very good hop flavours. Another minor issue is ensuring the fittings for gas and liquid lines are firmly attached. I thought my nukatap mini wasn’t working until I realised I hadn’t pushed it on fully.
