Has anyone used bags for their finished wine? Example - I bulk age a top-end wine kit for a year. At bottling, I bottle a dozen or two for 1 year+ additional ageing, and place the remaining wine into 1.5 liter, or other size, bags for consumption over the course of a year. According to a manufacturer: Bag in box delivers outstanding product preservation with up to 12 month shelf life. Bag-in-box maintains freshness and taste by protecting the wine from contact with oxygen while delivering high quality flavor in every glass. Consumers can expect fresh wine from 4 – 6 weeks after opening. Here's a link to a retail outlet. Although it's out of the country, I'm sure there are US sellers as well.
