A relatively (compared to others I have seen) moderately small collection of around 200 bottles, the majority stored in 2x72 bottle ebay-esque wine fridges). The remainders are just kept in boxes in the garage.
I discovered how one-dimensional my cellar was about 2 years ago when I printed my first cellartracker report that about 45% was shiraz, 35% cabernet or blends, and the rest a mix of mostly Chardonnay, Semillon, fortifieds and then various odd bottles. At the time, the largest producer represented was Penfolds (red capsules were all over the place), with Tyrrells, Katnook and Wynns close behind. Consequently the most commonly represented regions were Barossa, Hunter and Coonawarra.
I find I'm not drinking that many of the wines that I have stored as my tastes have certainly changed over time so I have been trying to rectify the quantities and go for smaller producers, slowly increasing in Pinot, Grenache, and foreign wines. While I still enjoy the big punchy favourites every now and then, I find it's a bit much and my current interest is less heavy wines such as Beaujolais, Burgundy (of which I only have a few bottles) and I'd like to get some more Aussie italian varietals for everyday food wines.

Cheers
