Primitive Beer's Flat Lambic Launches Bag-In-Box Format Once Reserved for Wine

It should be noted that this is a still beer, modelled after Belgian breweries that have long offered such beverages. The lack of carbonation, of course, eliminates the risk of the bag exploding inside of its corrugated box.

“When we launched in 2018, it was a year-old beer we put into these packages,” says Lisa Boldt, who owns Primitive with her husband Brandon. “Now we’ve settled on two-and three-year-old beers, which are more ‘finished’ in terms the amount of sugar that’s left to ferment. That means less likelihood of the bags puffing up as fermentation continues to take place.”

Assisting the Colorado brewer on the supply side is Astrapouch, which sources the bags, the corrugated box, and the Astrofil-1000 on which the bags are filled. The bag material, which has a total thickness of 115 microns, is a nine-layer coextrusion that includes PE/EVOH/Nylon/PE. The corrugated is a single-wall B-flute.
