ETS Laboratories Performs Analysis for Scott Labs’ Dry-Steam Validation Study

Petaluma, California – December 14, 2020 – Scott Laboratories, the leading supplier of packaging, equipment, filtration and fermentation products for the North American wine industry, is excited to share initial results as provided by ETS Laboratories for a validation study conducted by Scott Laboratories.

ETS Laboratories, an independent wine analysis lab headquartered in Saint Helena, performed the analyses on corks submitted to them to evaluate Scott Labs’ proprietary cleaning process for cork closures – a process Scott Labs has coined as “Dry-Steam” technology. The goal of the study was to provide Scott Labs with preliminary information on the efficacy of the cleaning process based on measuring TCA before and after the Dry-Steam treatment.

Scott Labs’ standard QC process rejects any cork bale that shows results higher than 1ppt of TCA. However, for the sake of this study, Scott Labs provided ETS with natural cork samples containing varying levels of TCA prior to receiving the Dry-Steam treatment, in order to completely and accurately test the efficacy of the technology on a wide range of corks.
Initial cork samples were individually tested by ETS Labs with significant results. All corks with less than 10ppt of TCA prior to receiving the Dry-Steam treatment showed undetectable levels of TCA (less than 1ppt) after going through the Dry-Steam process.

Alex Scott, President of Scott Labs, comments “We’re the oldest and only independent cork supplier in the US wine industry, continuously striving to produce innovative methods of reducing TCA and increasing overall quality in natural cork closures. By marrying individual inspection with Dry-Steam technology, we’re able to drastically improve cork quality beyond anything that’s currently available in the market. Backed by our Scott Promise, across all cork products, at no additional cost to the customer.”

Scott Labs is the only independent North American-owned cork company. Robert Scott, Alex Scott’s grandfather, imported the company’s first cork in 1974, making Scott Labs the oldest and most experienced importer in North America. The company’s enduring independence and integrity are the cornerstones of their cork program.

  • Independence protects customer interest over supplier interest. Scott Labs has the unique ability to accept only those lots of cork that meet the most stringent QC protocols in the world.
  • Scott Labs’ TCA testing protocols are done prior to purchasing raw materials. These tests are performed by independent labs to ensure 3rd party testing removes any conflict of interest within the supply chain.
  • As a family-owned organization with a mission and core belief in “education, honesty, and doing the right thing,” Scott Labs’ reputation rests on each cork and the transparency of their program.

Chris Holman, General Manager of Scott Labs’ Packaging Department, comments “Our motto is ‘The Clean Cork with a Clear Promise.’ When we sell something, we do it with an absolute guarantee. We believe that good cork starts with good raw material, and with our Dry-Steam technology we’re able to take the best raw material and make it impeccable.”
Due to the overwhelming success of their Dry Steam process, Scott Labs is now able to offer the Scott Promise™ program.
