Why, WHY boxed wine you ask? It started out as a mockery (I don't really need to explain the trashiness of box wine, do I?), but then became our unofficial mascot at UpShift because it's inexpensive (oh hell, let's just be super trashy and call it cheap) and essentially it's bottomless. To crank up the trash factor we drink it from a red solo cup.
One other reason; every time I point it out to our customers I get the same reaction - cringe, chuckle, pour. It's priceless that people get a kick out of our lack of standards, yet want to be a part of it.
