I do a combo between Hoffman's perfect single cup method and Scott Rao's method. I start with a wetted and warmed v60 with a wetted coffee sock cotton filter

1. Grind 18g coffee
2. Bring 400ml water to brew temp (I always heat up some extra water in case I spill or something)
3. Add bloom water until no dry grounds sit on the bed (usually about 40ml)
4. Swirl
5. Wait 30s
6. Excavate bed with tea spoon
7. Pour water until there's been 150ml water added to the whole situation
8. Swirl every 10s as the coffee drains down
9. Add the final 150ml (300ml should have been added now)
10. Swirl every 10s as the coffee drains down
11. You have coffee now
