At this point we have close to 200 bottles in our cellar. Alistair, I think has a fairly good idea, fantasini master of mystery slot of what we have but having said that we have lost a few great bottles that should have been opened sooner. We often bring back wine from our travels and it would be great for me to remember which ones came from where, if they were associated with a special occasion, etc. We will use our ipad (no app) and catalogue them by Country and grape varietal, including pictures with the intent to keep this updated as we add/remove bottles. This will also make it easier for me to raid our cellar!!
