A Decade of Impact with Rodney Strong Vineyards

When Rodney Strong Vineyards set out to reduce their environmental footprint ten years ago, they looked for more than a solution. They looked for results. Their switch to G3 Label’s GTREE™ paper stock—our label made from 100% post-consumer waste—has delivered measurable environmental and business benefits:

  • 2,295 trees still standing
  • Nearly 1 million lbs. of COâ‚‚ emissions avoided
  • Over 7,800 lbs. of solid waste eliminated
  • 178,845 gallons of wastewater not produced

GTREE™ stands up to high-speed bottling, cold storage, and mobile applications—while aligning with strong sustainability goals.

“Our Rodney Strong labels have been running on GTREE for 10 years, and we are very happy with the depth of embosses, saturation of color, and the integrity of the paper. It works beautifully on our bottles and always maintains elegance when placed in ice buckets on white tablecloths. We have confidence in the sustainability of the GTREE paper and value how much that gives back to the environment, which is a pillar for us in our partnerships with G3.”

– Erica Odden, VP of Marketing and Consumer Relations, Rodney Strong Vineyards
