When you're dying to kick back and relax with a good glass of wine but don't want to commit to opening a whole bottle, canned wine is an excellent option. However, just like how boxed wine expires faster than bottled wine, so too does the canned variety. Well, expire is a strong word. Canned wine doesn't necessarily expire, but can lose its quality over time. Typically, canned wine is labeled with a shelf life of between 12 and 18 months, though not all manufacturers stand by this time frame.
