Youngs----eBay has loads of youngs supplies.they are cheap and they ship to the US.
I am intrigued,this seems like a lot of cider!any chance of some pics of your set up?
Ok
Maybe I am being stupid here.
If at .9 I add **** loads or sugar the wine will not ferment more because the yeast can't tolerate more alcohol % and that's sweetening the wine???
(and I am drunk)
I think this is a good idea as the filters can vary in size,and if there is a submersible pump I am sure it could be set up for wine.for racking only though as I think the must would be far to much for the sponges in a filter to take....go for it!
(don't forget to post and show us your setup)
