CO2 purge of secondary carboy

Does anyone have an opinion on the efficacy and/or need for filling your secondary carboy with CO2 prior to racking into secondary? And does this mean you can let primary go longer to let the yeast do additional clean up?

Thanks, T

I don’t think it’s necessary. But some want to do every minute detail possible in the brewing process.

IMO, leave the beer in the primary for 3-4 weeks. You can dry hop, add fruit or oak in the primary. Unless you want to harvest the yeast.

Definitely not needed if you feel the need to do a secondary. You will have co2 coming out of solution with the racking.

Thanks, if I leave in primary for 4 weeks and dry hop there, then do you still recommend racking to secondary after or just to keg?
