Hi l made a red ale on February 12. I transferred it to a keg feb 26. I am cold crashing it today because it is warm (-2C now, up to +1C this afternoon). It will be -4C at 11pm, and to -9C overnight. About how long should I leave it outside for. My basement is +8C. When I bring it in I think I will just hook it up to the co2. Will this be a reasonable cold crash. Thanks
