Hi! O'Grower, the only thing that distinguishes a grape wine from another fruit wine is commercialism. Just because the romans liked grape wine does not make it the best, just easy to grow.
The usual way to rack/syphon a wine off is to block/plug the end of your tube and then cut an opening an inch from the end. You can then hold the tubing on the bottom and leave the yeasty muck in the demijohn. You may need assistance to rack or bottle as you should avoid disturbing the sediment. You can buy glass tubes with side entries if you prefer spending money.
I Like the Bruce Wayne quote, have you seen the adverts that say 'it what you are on the outside that matters' How shallow is that.
