So, back in the olden days, when the drinking age was only 19, it wasn't hard to be a wine snob. Really! All you had to do was say something snotty about California wines, be condescending about Boone's Farm ("Kool Aid for Sorority Girls" was a good place to start), and categorically refuse to drink anything that came with a screw top or in a box.
See? Easy peasy.
How things have changed.
Now, it's all about "California root stock saved the French wine industry" and "California wines beat French wines and are complex and subtle" and "screw tops are more environmentally friendly plus they do a better job of keeping air out of the bottle."
Plus--now box wines are no longer a joke.
There are lots of reasons, and some of them have to do with the fact that ALL the cool kids are blending varietals now in order to get a better wine, or a more consistent taste, or smoothing out the variations in grape production. But the best thing about box wine nowdays?
You can buy your own favorite kind of wine, and you never have to share it and you (almost) never have to throw it out. Look, even for an Evil person like me, it's hard to drink and entire bottle of wine by myself at one sitting. And as soon as you have to share a bottle, you have to negotiate what you are going to drink. Does the other person want red or white? Chardonnay or riesling? Oaked or unoaked? Sparkling or still? Viognier or Pinot Grigio? What if you don't finish the wine, even with two (or more) of you? What if you like your red wine chilled to Coca-cola temperatures?
With box wines, you get your choice, you don't have to share, and it keeps and keeps and keeps. You don't need to worry about oxidation, because the bag inside the box has been vacuum sealed and there's no risk. You don't end up with a $30+ bottle reduced to cooking wine--or vinegar!!--because you didn't come back the next morning and finish it up with breakfast.
Turns out that just about everything we thought we knew about wine was wrong.
Except for Boone's Farm. That's still Kool-Aid for sorority chicks.
