I nearly asked the other day what size batches you typically run. I did a couple 1-gallon batches and figured out really quick that the cleanup for a 1-gallon batch isn't much easier than the cleanup for a 5-gallon batch. I bottle as well, and have entirely too many bottles now, being the packrat that I am. I keep the bottles in the cartons so they stay dark while conditioning. I have what appears to be something of an anomaly under my stairs. Bottled beer will carbonate in about 2 days down there.
The missus has agreed to letting me build a keezer so I can try some cold fermenting. We're looking at a newer upright freezer to replace the older chest that we have that is not frost-free. I've thought about kegging, but the kegerator would be something else to plug in and add continual cost to the enjoyment. Not opposed to it, but it's me being stingy, I guess. I just put 6 bottles at a time in the fridge we have to run anyway. A large percentage of my bottles are recycled from craft/import beers that I've had, but I originally purchased 6 cases of bottles so I could keep several batches on the shelf at a time. Building a new shop through the summer kinda pre-empted some of the brewing, but I'm hoping to get back into it more since I was basically forced into retirement. I also ferment in the coolest closet in the darkest and least used room in my house. I use an underbed storage container to put my fermenters in just in case they decide to puke. I just try to make sure the temperature doesn't get above 72 down there, and since heat rises, that isn't too difficult. Don't have the spectrometer yet, just analog thermometers (mercury tube and dial, as well as one on the kettle). So far, I've tried to target beers that can ferment without chilling. But i want to get into more advanced brewing to expand my palate and maybe one day submit one for a competition. I've gotta get a lot better at it before then.
