1 pointAnother vote for distilling WITH lees. That said, we've never tried to rack above yeast for any product so ours may be more a matter of convenience as all of our pumping takes place out of the bottom of the fermentor. Never have had any trouble or undesired flavors with this method though.

1 pointCan't comment on how shelf life prior to wild fermentation, but... if you are driving out there to pick it up, just bring a slug of yeast with you and pitch it into juice. Should be bubbling away nicely by the time you get it back to your place.
