I have white wine fermenting in a 7.9 gallon bucket, lid, airlock. It is almost 6 gallons full. It is white wine off the skins. I usually rack wine into a carboy at around 1.020 or so. When I do this, I usually am not racking if off any lees. What I want to to this time is let the wine ferment out in the bucket as it is sealed with an airlock. I am assumin it will be purged of oxygen as it is bubbling like crazy and will continue for a while. Does anyone see a problem letting it sit in the primary for a couple weeks so it drops some yeast and material out of suspension? I am wanting to rack it off some lees as I will have to do it at some point anyway and it will save me racking out of the carboy so soon. If this shouldn't be a problem, how long would you let it sit in primary knowing it is sealed and purged of oxygen.
