Those boxes hold a lot of wine. And the wine is good. Great for a small group get together.

brands in plastic 750 ML bottles.

Not a problem if you are using TOPICAL isopropyl or other alcohol, but I surely wouldn't want to DRINK it.

I'm sure there will be those who say they've seen it or bought it and I'm sure there is a market for it, but my points remain. Plastic leaches.

What some would consider value priced brands all come in plastic containers. Miller Lite, Jim Beam, too many “box” wines to list.

And before anyone looks down their nose on me ....... There are some very good varieties out there. Plus, it's way cheaper than bottles.

My third shift weekend is over and I'm about to crash!

..plastic container and wines in boxes. But Ive never seen beer in anything but cans or glass.

But here's an andwer to your question.

Basically, wine in a plastic bottle has a shelf life of 6 months or less.

Wine and liquors sometimes are sold in plastic, but only the cheapest brands

Wine is a plasic bag in a box. You can get beer in plastic bottles. And you can find liquor in plastic bottles everywhere.

My son said, "You can tell that stuff is cheap cuz it's in plastic".

Turns out it was plastic. The guy who did it was shocked at the discovery and the dude who was clocked initially thought he had been hit with a glass bottle. Both just stood there giving each other dumb looks for a moment until the chaos resumed.

I can just picture this scenario and it has me LOL!

A Deplorable was walking down a wintry sidewalk with a pint of whiskey in his back pocket. He stepped on a patch of ice, lost footing, and fell on his ass.

Within seconds, he felt a puddle of liquid forming around him. The Deplorable looked up.

"Dear God," he said, "please let that be blood."

And a reality tv star is running the United States....did I reference Aldous Huxley, my bad....
It’s closer to something from Howard Philips Lovecraft......

The little "airline" size things are nearly all plastic now, and the box wines have a plastic bladder in them.

Now, as to beer, the only plastic container i've ever seen are those mini-kegs. But don't recall ever seeing a 12 or 16 ounce container of beer in plastic.
