OK Folks, read the following article. Especialy the part about the 'special' PET bottle. Two sentences stand out to me.
"allows putting premium products into PET while providing protection from oxygen and ultraviolet light"
“Yellow Jersey is the first PET oxygen-barrier 750ml wine bottle ever produced in North America. "
I read this article to say that these wine bottles are NOT the same as the PET liquor bottles.
BTW, four Yellow Jersey products are currently listed at the LCBO (Chardonnay, Pinot Noir, Merlot, Sauvignon Blanc). All at $10.95 for 750ml. Can't tell from the web-site if they are plastic bottles or not. Unfortunately none of the four are available in my home town, or at the larger liquor store that I expect to visit next week for a new product. I'll try to remember too look around though.
This is kinda llike the difference between a Better Bottle plastic carboy and regular PET. BB states that their PET plastic is much higher quality.
