[rguedr3]

I have access to a 4.3 cu ft mini fridge and I have access to a an older models 6 cu ft freezer with a419 controller. Which one will make for a better fermentation chiller?

The freezer, because it's bigger.

the freezer, its larger and chest freezers are usually more energy efficient b/c when you open a frig all the cold air rolls out were as a chest freezer has a top lid and most of the cold air stays in b/c cold air sinks and will stay in the freezer.
