Single-serve containers of wine are increasingly cropping up at retailers and finding their way into sports arenas, hotels and resorts, beaches and other venues. This trend has been accelerated by the commercial offering of pre-packaged wines that offer individual servings in “glasses” made of food-grade PET. These sealed, sterile and tamper-proof packages come filled with popular wine varietals.
There is a market for these beverages in places where disposed or broken glass could cause logistical or safety problems. Stack Wines, Anaheim, Calif., entered this market in 2013 with wines packaged in individual, sealed, un-stemmed plastic glasses. These containers are four-stacked into a tower around which a shrink-sleeve is placed to unitize the filled glasses into a single package.
