I share the health concerns raised, but I brew because I enjoy the process - even more so than the end result - so I share so much of the beer, that I don't have to worry too much about my consumption level. It has receded gradually over the years, so with the pandemic, the storage of beer became my biggest issue (instead of regularly having 10-12 people at my home on weekend evenings, there were just a handful of neighbors to occasionally send a growler home with if they stopped by to chat - at a social distance).
So, a cold room would serve several functions for me, including easier storage and handling of kegs and crashed fermenters and would take up less floor space than my three chest freezers currently in use. For example of consumption, I will be providing home brew for 3 parties upcoming this weekend and next week and being able to fit those kegs in cold storage is a challenge, given the other kegs already in the chest freezers. This week I will transfer (o2 free) from first kegs to brite, serving kegs for transport to the events. It would be nice to have a walk in cooler in which to do the transfers.
