I am considering making a cider for the wife in the near future. I have been eyeballing the unicorn blood recipe. My question is, since I plan on kegging the batch can I pasturize and back sweeten then directly transfer into my keg? I prefer not to use any chemicals if at all possible. I plan on using a brew kettle with a ball valve to heat up the cider then transfer, and I will have a lid on the entire time I am raising the temp. I'm not planning on going past 170°f to minimize alcohol boil off. Any insight would be appreciated.
