I've made 4 extract brews, so I am clearly new to the "art". I've been reading various threads on this site for a couple of months, so I'm becoming familiar with the terminology, equipment, etc., but I would like to confirm my understandings regarding a couple of areas.
1. I understand that some beers, lagers I believe, need to be fermented and stored at a relatively low temp...like 35F. Generally, the equipment used for this storage/fermentation is a converted freezer, preferably a chest type, with an external controller. If this is correct, with a collar, a smaller freezer can handle three or so cornies. I see plans and discussions about "son of somebody" coolers...are these for the same purpose?
2. The CO2 systems I see, sometimes called "kegorators" or what have you, are for cooling and dispensing beer in your home.
These two things are not dual purpose, but rather separate functions...right? If a person is making different types of beer with different fermentation temps, he would need maybe two temp controlled freezers? Gads, this could be expensive!
