What I have seen for multiple dry hops going like this:
- Primary until most of fermentation is complete - probably 3 to 7 days or so.
- Add in first dry hop and let stand for 3 days either in primary or move to secondary and dry hop there.
- After 3 days, remove first dry hop and add second dry hop for 4 days.
The dates are just recommendations and timing is somewhat flexible about when the first dry hop goes and how long each dry hop stays in. I've done 1 week primary, 5 days dry hop #1 and 5 days dry hop #2.
