I ave an auto siphon but use a vacuum pump to do this now. I used to suck start the fermentations for quite some time and never had a problem. Just sanitize everything and keep the S02 levels up and you will be fine. An auto siphon will make you wonder why you never bought 1 before just like a floor corker.
S02 is K-meta which is Potassium Metabisulfite and in tablet form is campden tablets. There is also sodium Meta (Na-meta) and is again also sold in tablet for called Campden. You ken get this stuff at a Brew and wine makers shop or order through the internet at places like http://finevinewines.com/
I tried to siphon the old fashioned way because my auto-siphon didn't fit in the 1 gallon jugs...One unfortunate wine-catastrophe later and I bought the smaller auto-siphon. There's no shame in letting technology aid you
I asked at my local home brew shop if you could get a mini siphon and they said no! Told me to harden up!! Actaully they just said to use the old fashioned method! Hmmmm guessing they are not in it to make a buck. I will try the net then, as Id much rather use the auto siphon if I can.
