OK, so I've increased my batch size...trouble is, to bottle now, I need to transfer the beer from the primary to the 60 quart kettle I use for an hlt and gravity feed to the bottle filler. Than involves lifting 10-12 gallons of beer onto a head high shelf. Did just that last night, next time I'm pumping it up there, so...I'm considering 2 options: 1. 25 watt Mark II connected directly to valve on the fermentor. or 2. small Seaflo diaphram pump and a stainless racking cane. Any thoughts?
