I'm fine with over carbed, I can deal with that as I am still trying to dial in my process.
I have an old boil kettle with gallon marks etched into the inside and a ball valve on the very bottom on the side, I think I'll be making this my bottling kettle next time.
I'll be looking into getting some glass etching material or maybe something less expensive and more simple for the carboys.
If this batch still tastes great and just over carbonated, I'll be happy and looking forward to making a 10 gal batch next time.
Thanks for the piece of mind.
