Yes, storing wine for long term consumption can be a big hassle, and more trouble than its worth.
If you are not really a 'wine' guy, and don't plan to have a wine cellar/cabinet/fridge, I'll probably go with one of these options:
1)Forget about storing the wine yourself. Buy the wine in the open market in 19 years time. You should be able to pick up some 2019 wine in 2039. You may have to pay a bit more, and the selection will be less, but you save yourself the headache of worrying about a case of wine oxidating and cooking. You may have to look into the US when buying, as they have larger supplies of wine vendors. But who knows what the world looks like in 19 years...Maybe the Ontario laws will change by then and you can ship wine into Ontario...Or you may not even be living in Canada.
2) If you are deadset on storing your own wine, then maybe just pick a 'cheaper' wine, put it away in your basement, and take the risk of the wine not drinkable in 19 years...It'll just be a novelty item for the celebration. don't put too much into it...maybe some 10-20 dollar Malbecs. If it still tastes good, then its a bonus.
3) Get some Port or Sherry to store for the 19 years. Port is not as susceptible to heat as non-fortified wines.
