A Central Coast producer is pouring wine into a new, much lighter container: a paper bottle. Monterey Wine Company in King City is using a Frugalpac machine — the only one of its kind in the United States — to mold bottles from recycled cardboard. The process folds and shapes a flat, colored cardboard sheet into a bottle-like outer shell and inserts a flexible, recyclable liner that actually holds the wine. The finished package, which appears as two pieces of cardboard joined together, is roughly five times lighter than glass.
Winery staff say the paper bottle brings notable environmental benefits. Shannon Valladarez of Monterey Wine Company estimates the paper format cuts the carbon footprint by about six times compared with traditional glass bottles. It also uses far less water in production — roughly one quarter of the water needed to make a glass bottle — and is easier and cheaper to transport because of its lower weight.
Quality control director Rohit Deshpande has put the paper containers through testing to ensure they protect the wine’s character. Deshpande reports no detectable off-flavors from the cardboard or liner and believes the bottles can safely store wine for about 15 to 18 months, similar to many wines intended for near-term drinking. He stresses the format isn’t meant for long-term cellaring; it’s aimed at everyday and mid-tier wines that compete on retail shelves rather than for aging.
The automated packaging sequence pinches, folds and molds the cardboard shell, then inserts and seals the inner liner. The completed unit is recyclable, and Monterey Wine Company says it can produce up to 2.5 million paper bottles a year. Valladarez also notes a marketing edge over boxed wine: the bottle-like shape stands upright on shelves and can compete visually with higher-tier bottles. For consumers seeking lower environmental impact and easier handling, the paper bottle offers a greener alternative to glass. (Reporting by Joy Benedict, CBS News, King City, California.)
