It is all in the packaging that sells the wines. No, it is not on the labels. It is replacing corks with screw caps which make it easy to open . Jon Fredrikson, an industry consultant based in the San Francisco Bay area, finds that Americans don’t want to bother themselves with uncorking the bottle every time they want a peg. Such wines come in boxes, with spigots that keep the air out, thereby making the wine last longer; retaining its taste and quality. Boxed wines have become a craze now, as it is not the 5 liter box variety, costing $5.99, it’s the 3 liter box costing $4 to $5 and giving a better quality. Earlier boxed wines were inferior, but now people have changed their idea about screw caps, they have probably got bored with the corks. Well, we have to wait till they are bugged down with the concept of unscrewing bottles.
