I've got an extra sankey keg with the top cut off that it not being used so I figured I would make a 10 gallon fermenter out of it. I see no problem in fabricating some sort of sealing clear lid for the top but as far as the ball valve goes...any opinions on the best location? Here are the different placements I've seen:
1. Very bottom of keg.
Pros: No siphoning (or CO2 pressurizing) when transferring
Cons: ??? (Yeast plugging or being drawn out when transferring???)
2. Side of keg with siphon dip tube
3. No ball valve, use transfer siphon tube only
Pros: Being able to move around tube to avoid sucking up yeast
Cons: Without a sealed keg, you cannot start the siphon with CO2 pressurization
I like the idea of the bottom so I can pull yeast off for harvesting, but is this realistic without the conical shape? I figured I'd see if anyone had any input before I put the welder to the keg.
