No corkscrew necessary, thanks to Stack Wines

Cabernet Sauvignon Family 1 (2)

As a reward for a long day of work, you open a bottle of wine and have a glass or two. The following night, a friend treats you to dinner. The next night, there’s an impromptu corporate happy hour. Days later, you’re dismayed to find that your wine isn’t fresh enough to finish.

Too familiar with this scenario? Similar instances prompted Matt Zimmer, a mechanical engineer who worked in the bottled water industry, to think outside the bottle. In 2011, he launched California-based Stack Wines with fellow University of California, Irvine M.B.A alumni Jodi Wynn and Doug Allan. The company created its signature stackable wines–sold as a pack of four individual glasses.

Encased in Stack’s patented vinoware, a sturdy plastic that prevents the wine from spoiling, the wines come in four varietals: charisma, pinot grigio, chardonnay and cabernet. Priced at $12.99 online, and found at retailers in California, each four-pack holds the same amount of wine (750 ml) as a traditional bottle.

The wines are ideal for picnics and barbecues, outdoor concerts or for those nights when you crave a glass and don’t want to commit to an entire bottle in one sitting.
