I currently use a basement closet as my cellar Phil. Even though it is in the basement it does get a little warmer than I would like at certain times so I have been considering the whole room approach as we don't use that room often at the moment. If I do decide to go that route I will take some pics.
I posted a blog topic on cellaring beer some time ago so if any are interested they can check that out. It was called "To Age or not to age?"
At the moment I have 367 bottles. There are a lot of duplicates as I have 103 unique beers in that count. Some are favorites that I like to enjoy all year round, others are there with the intent of doing vertical tasting 3-5 years out or even more.
