Brewfather Back liquoring

[Jordang]

Hi, has anyone used Brewfather to calculate gravity in the FV that includes back liquoing?

Basically I want to do a split batch of 2x23l in my G40 so was thinking brew stronger and back liquor to the required gravity and volumes. However, I can’t figure it out on Brewfather!!

Thanks….

Unless I have misunderstood…

Set your equipment profile to a fermenter target volume of 46l. Set fermenter top up to however much water you will add at the end eg 6l.
