Wayfinder Joins the Margaret River Lightweight Glass Charter
Wayfinder Wines has officially become a full signatory to the Margaret River Wine Association (MRWA) Lightweight Glass Charter, further strengthening our commitment to sustainable wine production and reduced environmental impact.
The decision aligns naturally with Wayfinder’s broader sustainability philosophy, following the completion of our purpose-built, off-grid winery in Cowaramup ahead of Vintage 2026. Sustainability at Wayfinder is not a single initiative but a series of practical choices from regenerative viticulture and organic certification through to energy independence, winery design and responsible packaging.
A Winery Designed With Impact in Mind
Completed ahead of the 2026 vintage, the Wayfinder winery was designed from the ground up to minimise environmental impact while improving the quality and care of the winemaking process.
Constructed partially below ground level, the building uses rammed earth walls to provide natural thermal stability, reducing energy demand for temperature control. A gravity-flow design limits mechanical handling of the fruit and wine, allowing grapes to move gently through the winery while lowering energy use.
The structure integrates into the surrounding marri and jarrah forest landscape, reinforcing the estate’s broader vision of working with the environment rather than against it.
The vineyard itself has been certified organic since 2022, and in January 2026 the winery achieved Australian Certified Organic (ACO) certification, another step in ensuring that every stage of production reflects our environmental commitment.
Why Lightweight Glass Matters
The MRWA Lightweight Glass Charter is a regional initiative aimed at reducing the carbon footprint associated with wine packaging.
Glass production and transport are among the most significant contributors to emissions within the wine supply chain. The Charter commits signatories to reducing the average weight of a 750ml still wine bottle to below 420 grams, a practical and measurable step toward lowering greenhouse gas emissions.
By becoming a signatory, we formally commit to reducing packaging emissions as part of our broader sustainability strategy that includes regenerative farming, energy independence, low-impact winery design and responsible supply chain practices.
Just as importantly, the Charter provides a clear signal to trade partners and consumers seeking producers who are taking meaningful action to reduce environmental impact.
A Regional Effort
MRWA CEO Amanda Whiteland welcomed Wayfinder’s commitment to the initiative.
“Wayfinder has embedded sustainability into every aspect of its business, from vineyard to winery design. Lightweight glass is a simple but powerful initiative that complements their broader environmental leadership.”
She added:
“The Margaret River Wine Region has an opportunity to lead globally in sustainable wine production. Every additional signatory strengthens that leadership and sends a clear message to trade and consumers alike.”
A Practical Step Forward
Wayfinder CEO Paul McArdle says joining the Charter was a natural next step.
“Our new winery gives us complete control over the winemaking process while staying true to our environmental commitments. Lightweight glass is another practical measure that supports our long-term goal of reducing impact without compromising quality.”
While seemingly small, packaging choices have real impact across the wine supply chain. Lightweight glass reduces emissions during manufacturing, lowers transport weight, and helps move the industry toward more responsible production.
At Wayfinder, it’s one more step in a broader journey of regeneration, producing wines that reflect both the site on which they are grown and produced and the responsibility we carry to care for it.
