Also, in the other direction, I'm assuming this will hold up well with heat. I'm thinking this would work well with a ferm-wrap or heating pad to really crank up the heat on a saison.
Hi, Good questions!
1.) You should be able to easily cold crash in a 62 degree basement. This would require about a 20-25 degree drop from the ambient temperature.
Please see these testing results in a 80-85 degree room. There was no problem keeping temps 20-25 degrees colder than the ambient temp.
This was a 5 gallon batch in a 6.5 gallon plastic fermenter. This batch had 2x 2 liters and 2x to 4x 20oz changed every 24 hours. The wort was a little too chilled to begin with so ice was not added until 48 hours on Saturday
2.) We will work on testing with Fermwrap and heating pads and report back!
