Flame out and reduce to 90ºC and add 25g of Cascade and peel of one grapefruit. Whirlpool if possible.

Peel the 2 remaining grapefruits and keep in the fridge with a splash of vodka to sterilise.

Add one peel of one grapefruit during peak of fermentation (likely 48 hours)

Add 25g of Cascade and peel of one grapefruit at around 1.020.

Cold crash with gelatin finings for 48 hours then bottle/keg.
