I love love love LOVE my CurTec fermenters.
They clean up in 2 minutes.
After using CO2 to push out the beer to serving kegs, open them up rinse, them out, use a fiber cloth to wash them out with some hot water, all the sludge just literally falls off, it is like nice non-stick teflon pan.
Rinse again, add some starsan and a fiber cloth, put the lid back on, put in a stopper and swish around the starsan and store.... 2 minutes, DONE.
Not adding chemicals, in a dark container, that you can not see in...on and on....open the top of these, wash them out and move on with your life
These units hold 3 plus pounds of pressure.
I drill a 1 1/8" hole in the lid and use different stoppers for fermenting, cold crashing and pushing beer out. of them. I cold crash these under co2 pressure of 3 pounds to ensure the cold beer is taking on co2, not room air oxygen.
They are light, dont break... on and on and on... they are cheap.
Everyone should have 3 or 4 of these, seriously.
All the time I have wasted and spent on stainless kegs sanke kegs, cleaning them, wondering if they are clean, cussing them...ugh. Carboys, etc are easier but still a pain... makes me sick that I did not find these sooner, all the time and money I have spent on other systems before these....ugh.
Oh yeah... the delivery man will deliver them to your house, no running around town to get them, the ebay seller is very easy to work with also....win win win.
Buy some and dont look back and then sell whatever else you are using.
good luck to all
Kevin
