So here is a bit of a background on my brewing experience and set up. I have been brewing for a little over a year and still doing mostly extract and partial mashes. With my last brew I did a swamp cooler and liked the results. I've wanted to build my on fermentation chamber out of an old fridge or freezer, but as I thought about it I realized I live in a two bedroom apartment and I don't really have the space for a fermentation chamber. My next thought was to build the some of a fermentation chamber which seems easy enough. But a couple weeks ago I saw an add for the cool brewing fermentation cooler jaket thing and was wondering if it was worth it to buy and how well it works. Thanks in advance.
