ETS Laboratories Expands California OperationsETS Laboratories, the world’s leading independent laboratory serving the global wine industry, has opened a new ISO-accredited facility in Paso Robles, California. The new ETS location will fill the need for technical assistance and laboratory support for the California Central Coast’s rapidly growing wine industry, from grape growers to winemakers.
The new laboratory, which has received ISO 17025 accreditation, will be the first ISO-accredited wine laboratory in the Central Coast. "To some people, test results are nothing more than numbers. It’s important to realize that not all numbers are created equal,” says Gordon Burns, CEO of ETS Laboratories. “In order for analytical results to have any value to a winemaker, they have to be unquestionably reliable and accurate.” The ISO 17025 accreditation, which requires ongoing audits, specifically evaluates a lab’s ability to produce precise and accurate results.
This new space in Paso Robles houses both the new ETS laboratory and Scott Laboratories, a fermentation products and winery equipment retailer. This arrangement allows winemakers to drop off samples and procure winemaking supplies in one location, saving time and travel during the hectic harvest and crush season. The location is open 7:00am to 7:00pm weekdays (with extended weekend hours during harvest) and is located at 3320 Ramada Drive, just off of Highway 101 in Paso Robles.
ETS Laboratories continues to grow alongside the wine industry, from California to Oregon and Washington, making its new location in Paso Robles and recent expansion in Oregon a natural step for the company. ETS’s new laboratories bring new techniques and equipment to their respective areas, giving winemakers local access to some of ETS’s most advanced analytical tools. Having the latest technology on-site means that ETS is able to expand their local offerings, including an HPLC for phenolic analysis and local service for most their export analyses.
“What we provide from our labs is more than technology and precise data, we provide expertise,” says Dr. Richard DeScenzo, Microbiology Group Leader at ETS Laboratories. “Our specialized technicians and scientists become an integral part of your winemaking team, helping interpret the results of our work so that winemakers and grape growers have a full understanding of both the tests and the results.”
Watch for future updates about ETS Laboratories’ expanded services as they prepare for the upcoming 2016 harvest. Information on all ETS locations and services may be found on their website at www.etslabs.com.

Central Coast Alert for BotrytisIn response to multiple client calls from the Santa Barbara and San Luis Obispo regions, we want to remind all of our clients that early detection of laccase activity in fruit enables early intervention, minimizing oxidative damage to juice and wine. Our facility in Paso Robles can provide rapid analysis for early detection of laccase activity.
-
Laccase is an enzyme primarily produced by the grape pathogen Botrytis cinerea.
-
Laccase can negatively impact wine by causing oxidation of phenolic compounds in wine, resulting in premature browning of bottled white wine and color degradation in red wine.
-
Juices/wines identified as containing laccase activity should be maintained in a reductive state to minimize browning and discoloration, and should not be blended with wines that do not contain laccase.
-
Early detection of laccase enables winemakers to take appropriate actions to minimize the impact on the final wine product. These can include increased SO2 additions at harvest, treatment with pectolytic enzymes, and use of enological tannins to bind laccase.
Different treatment strategies are required depending on type of juice/wine and severity of infection.
For further information on Botrytis/laccase problems, feel free to give us a call at (707) 963-4806 and talk to our Botrytis/laccase specialist, Dr. Rich DeScenzo.

ETS Adds Glutathione Analysis for Protection of White Wine AromasThe increasing demand for white and rosé wines with fresh, fruity or floral characters has led to significant winemaking challenges:
Because the aroma compounds in these lighter wines, such as Sauvignon Blanc, are fragile, oxidation can quickly cause a loss of aroma and flavor.
Even wines like Riesling and barrel-aged Chardonnay have experienced premature or atypical aging as a result of oxidation.
The importance of glutathione
Glutathione, a natural tri-peptide found in grapes and wine, is a powerful antioxidant that protects white wines and rosés from oxidation and loss of aroma or flavor.
A low level of glutathione in grapes leads to lower levels in the juice, and early losses of aroma compounds.
Glutathione levels fluctuate during production, as the compound can be absorbed by yeast and then released after fermentation.
If final glutathione levels are low in young wines, they will experience faster loss of fresh varietal and fruity aromas, and poor aging potential.
Glutathione interacts with other juice and wine constituents such as SO2, wine phenolic compounds, ascorbic acid and copper. These interactions affect both glutathione concentration as well as total juice or wine antioxidant status.
Monitoring glutathione
Monitoring glutathione levels can be beneficial at all steps of the winemaking process to maximize white wine aroma and flavor, and prevent premature aging.
The glutathione content in grapes indicates their antioxidant potential, and can be influenced by a number of factors including soil nitrogen, vineyard practices, and grape maturity levels.
Analyzing changes in glutathione levels during production helps to pinpoint where in the process glutathione is being lost – often from contact with air or exposure to copper residues.
A testing program can also identify winemaking processes that boost glutathione release after fermentation, and increase levels in wines.
For more information about glutathione analysis, contact Eric Herve or Steve Price.
Sampling Note: Juice samples are very sensitive to oxidation and loss of glutathione. ETS has created sampling kits that we provide free of charge for glutathione analyses to ensure accurate results.

ETS Laboratories Performs Analysis for Scott Labs’ Dry-Steam Validation StudyPetaluma, California – December 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.
Scott Promise: 100% clean cork or Scott Labs will buy the bottle back. Every cork, every day, at no additional cost to the customer. Winemakers can have confidence that their wine is protected, and quality is preserved with 100% clean cork purchased from Scott Labs. That’s their way of doing business. To find out more about what the Scott Promise program entails, as well as the applicable terms, limitations and conditions of the Promise program, visit https://scottlab.com/cork independence.
