"The relationship I had built with M. A. Silva is the reason I moved everything to them"
Erica Stancliff, a consulting winemaker renowned for her meticulous attention to detail and unwavering commitment to quality, has been working with M. A. Silva since 2010. Initially, she relied on M. A. Silva solely for corks. However, by 2015, her trust in their products and services grew so much that she transitioned all her clients’ packaging needs, including specialized glass molds and box printing, to M. A. Silva.

Stancliff’s decision to move everything to M. A. Silva was not made lightly. The catalyst for this shift was the exceptional relationship she developed with their team. “The relationship I had built with M. A. Silva is the reason I moved everything to them,” Stancliff explains. The previous glass vendor she used had consistent issues with variability, delivery problems, and a lack of reliable customer service. These challenges were particularly problematic given the complex logistics involved in managing multiple clients, vineyards, and appellations.
In the world of winemaking, timing is critical, especially when arranging multiple bottlings around the precise delivery of materials. Working across six different brands with a variety of SKUs, Stancliff has to manage a complex array of sizes, counts, and other variables. In such a high-stakes environment, having a reliable partner like M. A. Silva has been invaluable. “If anything ever goes wrong, I know M. A. Silva will answer and help find a solution,” she says.
Trust is the foundation of any successful partnership, and for Stancliff, being able to hand off projects to M. A. Silva with the confidence that they will be executed perfectly has been a game changer. Keeping orders and billing straight is no small feat, but M. A. Silva’s transparency and organization have made it easier for Stancliff to stay on top of her responsibilities. “They are very good at staying organized and staying on top of it. I rely on them a lot to keep myself organized,” Stancliff shares. Whether it’s dealing with changes in billing or navigating potential snags, M. A. Silva’s clear communication and willingness to find workarounds have made them an indispensable partner.
M. A. Silva’s commitment to transparency extends beyond day-to-day operations. Stancliff appreciates their candidness when discussing broader issues, such as potential tariff changes or other barriers that could impact the supply chain. Despite these challenges, she continues to find M. A. Silva’s offerings aligned with her cost comparisons, ensuring that she receives value without compromising quality.
One of the highlights of Stancliff’s relationship with M. A. Silva was a trip to Portugal, where she had the opportunity to see the cork forests firsthand. “Watching the cultural pride around the forests and how much is centered around that industry was fascinating,” Stancliff recalls. She was particularly struck by the sustainability practices in place, where every part of the cork is utilized—even the dust. By choosing M. A. Silva’s corks, Stancliff not only supports sustainability but also helps keep people employed and contributes to the preservation of an entire ecosystem.
For Stancliff, working with M. A. Silva is about more than just business; it’s about making the right decisions for the environment and the people who depend on it. “I know I’m making the right decision, but now I am convinced and proud to be supporting it,” she concludes. With M. A. Silva as a partner, Stancliff can continue to focus on what she does best—creating exceptional wines—while knowing that the materials and practices behind each bottle align with her values of quality and sustainability.

SANTA ROSA, CA: November 11, 2024 – M.A. SILVA, a global leader in the cork industry, proudly launches NOBELTECH®, a groundbreaking innovation that combines artificial intelligence with premium cork production. As the first cork company to utilize AI to ensure unparalleled product quality, M.A. SILVA sets a new industry standard with its NOBELTECH® and NOBEL CORKSTOPPERS® product lines, merging tradition with cutting-edge technology and sustainability.
The NOBELTECH® platform integrates three advanced technologies to deliver the most performant and sustainable corks available on the market.

A continuous and automatic extraction process ensures the removal of volatiles for sensory consistency. The system uses controlled temperature, pressure, and dry steam to preserve the cork’s elastic memory, safeguarding its structural integrity. - BIONICEYE® – AI & Machine Learning
This technology employs ultra-sensitive cameras and machine learning algorithms to perform piece-by-piece selection and grading.

Andy Schweiger
Some may say Andy Schweiger has his head in the clouds. His winery, is, after all, 2,000 feet off the valley floor on the top of Spring Mountain. With such lofty fruit, one can imagine Andy has top-level quality goals for all his suppliers.
Indeed, Andy admits to working with many different cork suppliers for years to establish his own meticulous list of criteria, service expectations, and quality control standards. “Other companies would nod at my requirements and gave me lip service,” recalls Andy, “but MAS actually listened and took my requests to heart.”
Since that first meeting, M. A. Silva has endured at Schweiger by striving for increasingly high quality in all Andy’s cork deliveries. By periodically announcing new technological innovations like the Dynavox system and SARA Advanced process, the supplier continues to methodically test and improve so they can deliver the highest level of quality cork for every order.
Andy cites M.A. Silva’s penchant for technological advancement in an otherwise ancient process as the secret to their high bar for quality. He explains that his sales reps are perpetually working to improve and educate. “I continue to learn things from them. It’s a true partnership. We support each other – it’s not a relationship where they just sell me things and I just pay them.”
“With former vendors I kept running into a choke neck problem, but as soon as I switched to the product from M.A. Silva, I haven’t had that issue and we’re able to get more consistent fill heights.”
– Winemaker Andy Schweiger
Andy got so comfortable with M.A. Silva with his cork supply that he eventually switched his glass purchases to the company. In the glass marketplace, Andy feels M.A. Silva provides an exceptional quality for the price. “The molds and shapes that they provide and have readily available Is visibly identical of the forms you get from France at 10x the cost,” says Andy.
He continues to explain that M.A. Silva continued to meet his extraordinary quality expectations as his new glass supplier. He found the glass quality control conducted by M.A. Silva to be much more reliable than with former vendors. “With former vendors I kept running into a choke neck problem, but as soon as I switched to the product from M.A. Silva, I haven’t had that issue and we’re able to get more consistent fill heights.”
That continual top-level quality doesn’t come at the expense of sustainability. The lightweight bottles are a hit with both his staff and his clients. Andy can keep his case weight at 38lbs – which is one of the items on Andy’s checklist. “Our staff don’t break their backs and shipping fees don’t break our customers banks,” he says.
The more checks Andy can mark on his quality checklist is all good news for Schweiger Vineyards. Andy knows by partnering with M.A. Silva to meet his high demands, he can keep shipping wine from his mountaintop to his consumers, and trust his wine is in top form.
