Perhaps Sirs means when a celebrity either owns a winery or lends their name to a winery. Here in Ontario, I can think of three...Wayne Gretzky, Mike Weir, and Dan Aykroyd. I don't think any of them make a "collectable" wine. Maybe the empty wine bottle.

I drink almost no commercial wine, so no I haven't. I haven't even visited the wineries, even though they are in the neighbourhood (ie probably within about 30 mn from here).Have you tried any of the Gretzky or Weir wines ?
