A minor part of my assets (which I don't even bother including in my Net Worth estimates) is a small wine collection. I don't drink much wine, but I enjoy reading up on the Australian wines that are "collectible" and have bought and stored a few bottles of Grange hermitage, De Bortoli "noble one" and some others. My biggest problem has been not having somewhere to store these wines. I initially did the usual "under the staircase" wine rack thing - but, especially in Summer, this is NOT a suitable location. Even with some insulation and air conditioning the humidity would not be optimum. I've now shipped the wines up to my parents farm, where they have a suitable underground wine cellar area, but I still not to set it up properly and monitor the conditions.
