Wine is a $2 billion industry in Washington state, but many students will not be exposed to the science behind the field as a possible career option until they reach college. Thanks to the Partners in Science program, however, one high school teacher had the opportunity to shadow and complete research alongside a renowned wine science researcher and professor at Washington State University Tri-Cities – the science behind the experience, of which, he is now introducing to his high school students.

Fred Burke, science teacher at Chiawana High School, sets up equipment for a smoke taint trial at the WSU Prosser Research Extension vineyards. He was paired with Tom Collins, assistant professor of wine science at WSU Tri-Cities, to complete wine research the last two summers at WSU Tri-Cities as part of the Partners in Science program.

Fred Burke, a teacher at Chiawana High School, had the opportunity to shadow and complete research with Tom Collins, wine science researcher and assistant professor of wine science at Washington State University Tri-Cities.

“This experience has allowed me to show my students how the nature of science is more than what they experience through a text book and allow them to experience the techniques and capabilities of it in a real-world setting,” Burke said. “It has not only allowed me to participate in research that will have an impact in the wine industry today, but it also it makes doing science a lot more fun for my students.”

Through the Partners in Science program, which is supported by a $15,000 grant from the MJ Murdock Charitable Trust, high school teachers are paired with a university professor in their field and the pair spends two consecutive summers completing research. During the end of each summer experience, the teachers prepare a presentation on their research and how they plan to implement what they learn into their classroom setting. The university professors also get the value of an additional hand in the lab and in the high school teacher’s second summer, an experienced lab researcher to help with their studies.

As part of his research experience, Burke worked with Collins to characterize wine grape varieties using sophisticated research techniques known as gas chromatography and mass spectrometry. For the techniques, the researchers use devices that allow researchers to look into the intricate chemical and other properties of each type of grape for classification and categorization. Burke also had the chance to work with Collins to start a study analyzing the impact of wildfire smoke on wine grapes, which could hinder the taste and overall quality of the wine.

Tom Collins, assistant professor of wine science at WSU Tri-Cities, prepares smoking equipment for a smoke taint trial to evaluate the effect of smoke on wine grapes at the WSU Prosser Research Extension vineyards.

“Both projects are relevant to the classes we’re teaching,” Burke said. “In environmental science, we’re able to look at how the smoke impacts not only the wine grapes, but also the chemical components and properties of the wine.”

The study of the impact of wildfire smoke on wine captured the interest of the Washington wine industry, with Collins stating that since they announced they were completing the research, he gets calls throughout the year on updates for the research, results they’ve tabulated and generally how they can protect wine grapes from the exposure. The interest grows each year as the summer wildfire seasons commence.

“We got three calls today, alone, regarding smoke taint,” Collins said. “The fact that Fred has been able to be a part of this project provides him with a great in-depth look at how lab and field research have a substantial impact on industry. The Washington wine industry increases exponentially year, with the mid-Columbia region being a hub for the industry. So this research is crucial for our area’s winemakers.”

Last summer during Burke’s first of two summers working with Collins in the lab, the duo set up experiments at the WSU Prosser Research Extension to test different amounts of smoke on grape vines. They are now in the process of analyzing samples collected from that experiment. Collins plans on continuing the study for at least the next several years.

“Just being able to look at all the parts that go into a real-life field of scientific study has been immensely beneficial,” Burke said. “I get to share that with my students and they benefit from that real-world application. Within their science classes, our students have to conduct procedures, collect data and analyze that data through labs and lessons. This real-world experience allows me to show them that what they’re practicing in class can be applied out into the field, as well as provide them with concrete examples of stuff we’re actively doing in the labs.”

Burke also had the opportunity to bring some of his classes out to the Ste. Michelle Wine Estates WSU Wine Science Center to see how the research is conducted and get an idea of how a research lab operates.

“Science in agriculture is kind of one of those unknowns for many of my students,” he said. “They see people planting and watering, but they don’t know the science behind it. This provides them with an in-depth look. It’s a career option that most of my students probably have never even considered.”

Burke plans to apply for a supplemental grant from the Partners in Science program, which would extend his research partnership time frame with Collins and provide Burke with dollars for science equipment for his classroom.

“It would provide us with more money for use in the classroom, which would allow my students to conduct some research of their own,” he said. “It’s a great opportunity.”

RICHLAND, Wash. – A recent study conducted by a Washington State University Tri-Cities faculty member indicates that holding at least one internationally-recognized wine credential could have a positive correlation on the number of social media followers a wine blogger may have.

The results of the survey were published recently in the International Journal of Hospitality Beverage Management.

Byron Marlowe, a clinical assistant professor of hospitality and wine business management in WSU Tri-Cities’ Carson College of Business, surveyed 30 prominent wine bloggers with Twitter accounts. During a 45-day period, he tracked the number of Twitter followers they had, whether they posted about and recommended international wine destinations on their account and the wine credentials they listed. The bloggers selected for the survey had a minimum requirement of 500 Twitter followers.

The analysis indicated that wine bloggers with at least one credential from the nationally or globally-respected certifying bodies for wine credentialing had an average of 75 percent more followers than those without certifications. Those certifying bodies included: The Court of Master Sommeliers, Wine and Spirits Education Trust, Society of Wine Educators, Culinary Institute of America, International Sommelier Guiled, Sommelier Society of America and the International Wine Guild.

“The wine bloggers who went through the certification process received knowledge and expertise that make their recommendations inherently more meaningful, even if their followers did not know of their certifications,” Marlowe said.

The survey also showed that bloggers with higher credentials were more likely to recommend an international destination for wine consumption or purchase. Marlowe said bloggers that didn’t have certifications may simply not have had the international experience to review those types of wine or the regions from which those wines were created.

“A wine blogger without a certification may not have visited or studied in Burgundy, France, for example, because they didn’t have knowledge of the region or the need to be there to pass an exam for their certification,” he said. “So they wouldn’t have the background or motivation to recommend that destination or wine region.”

Grapes are pressed for winemaking at the Ste. Michelle Wine Estates WSU Wine Science Center at WSU Tri-Cities.

As a result of the survey, Marlowe recommends wine bloggers consider obtaining established certifications to heighten their credibility, and as a result, help potentially increase their number of followers on social media platforms and increase their brand reach.

WSU conducts a one-year wine business management certificate program for those looking to expand their knowledge of the industry. The certificate consists of six modules offered in an online format and requires two weekend experiences in Washington wine country. These weekend experiences provide students with an opportunity to network and learn with wine industry professionals, faculty and fellow students about the business of wine.

Marlowe’s research is in line with WSU’s Grand Challenges, a suite of research initiatives aimed at large societal issues. It is particularly relevant to the challenge of sustaining resources with respect to food production and related business.

RICHLAND, Wash. – A team from Washington State University recently took home top honors in the research poster competition at the Worldwide Distilled Spirits Conference in Glasgow, Scotland, for research on a technique typically used to evaluate the characteristics of wine.

To determine the characteristics and compounds in wine, researchers combine a wine sample with a mixture of water and octanol, which is a fatty alcohol. As a result, different compounds from the wine separate and enter into two phases: octanol and water. The relative separation of the compounds into the two phases is known as the beverage’s hydrophobicity.

These two phases are then analyzed using mass spectrometry, a sophisticated technique that identifies the individual compounds within those phases. The identified compounds can help determine the astringency, or mouth feel, of the wine as well as the color and other sensory factors.

Wine scientists expand applications

Jim Harbertson, Caroline Merrell and Tom Collins (l-r) display some of their major findings in distilled spirit analysis application.

The WSU Tri-Cities team, which consisted of wine science postdoctoral researcher Caroline Merrell, associate professor of enology Jim Harbertson, and assistant professor of wine science Tom Collins, decided to analyze distilled spirits using the same process.

“It started off as ‘let’s see what happens when we apply this technique to a product other than wine,’” Collins said. “Spirits make sense for this analysis not only because of their similarities to wine, but also their differences. We expected to extract different things from the barrels for spirits than for wine, and I think we clearly see that with our findings.”

A measurement in wine is used primarily to evaluate phenolic composition, Harbertson said. The phenolic composition, derived from the grapes and barrels, affects the taste, color and mouthfeel of wine.

“But in spirits, the phenolics are only derived from the barrel, so the process provides an interesting piece of the puzzle,” he said.

Whiskey, tequila, rum, cognac

In their research, team members examined a range of distilled spirits including American whiskey (bourbon), Scotch whiskey, Irish whiskey, tequila, rum, cognac and Armagnac. The barrel type used in the aging process for these spirits significantly impacted the identified compounds, Merrell said.

“For instance, all the bourbons separated out together as part of the statistical analysis,” she said. “Bourbon is made in new, heavily charred barrels. Because bourbons use newly charred barrels, there is more extraction of different phenolic and flavor compounds during aging. All the other spirit types age in previously used barrels, which have already had substantial amounts of phenolic and flavor compounds extracted.”

Barrel selection insights

Their initial research shows the importance of barrel selection in making distilled spirits. The hope is that it will give the industry more tools for making alcohol, Merrell said.

“Our research gives the industry more insight into the effects of barrel selection for different types of spirits,” Collins said. “We had a fair amount of interest from distilleries after the presentation, and we look forward to opportunities to collaborate and explore these effects in more detail.”

The team hopes to expand their research beyond commercially available products. The plan is to acquire distillation equipment at the Ste. Michelle Wine Estates WSU Wine Science Center to prepare, develop and analyze their own spirits.

To his knowledge, this is the first time anyone has used the hydrophobicity technique to examine the components of distilled spirits, Collins said.

RICHLAND, Wash. – Four Washington State University professors are pairing up with high school teachers in the Tri-Cities this summer to complete research in viticulture and enology, bioproducts engineering, plant pathology and biological sciences through the MJ Murdock Charitable Trust’s Partners in Science Program.

MJ Murdock Charitable Trust is providing $13,000 to each high school teacher participating, which may go toward research, professional development and other educational resources.  Each team will also receive $2,000 to cover the costs of lab supplies during summer research opportunities in WSU laboratories.

The goal of the program is to bring knowledge from the research lab into the high school science classroom, promoting hands-on science education. The WSU professors will serve as mentors to each of the high school teachers as they complete the research throughout the course of two summers.

Viticulture and enology

WSU Tri-Cities newsThomas Collins, a WSU Tri-Cities assistant professor of viticulture and enology, is working with Frederick Burke, a science teacher at Chiawana High School, to characterize different grape varieties by region, utilizing a process known as gas chromatography/mass spectrometry.

“The process allows us to identify specific chemical profiles in each grape type, which will be used to identify markers associated with the various grape varieties.” Collins said. “The markers will be incorporated into statistical models that would be used to predict the grape varieties used to produce an independent set of Washington state wine samples.”

Biological sciences

WSU Tri-Cities newsElly Sweet, a WSU Tri-Cities clinical assistant professor of biological sciences, and Jim Cooper, a WSU Tri-Cities assistant professor of biological sciences, is working with Amy Verderber, a teacher at Kamiakin High School, to study the impact of thyroid hormone on zebrafish jaw development.

The team is performing development shape analyses of the skull and record and analyze high-speed video footage of fish feeding, in addition to zebrafish husbandry, specimen collection, specimen preparation and photomicroscopy.

“This study is strongly relevant to human health, since there are a large number of human craniofacial disorders associated with alterations of thyroid hormone in blood levels,” Sweet said.

Bioproducts engineering

WSU Tri-Cities newsXiao Zhang, a WSU Tri-Cities associate professor of chemical and bioengineering, is working with Robert Edrington, a science teacher at Southridge High School, to synthesize new functional materials from cellulose, the largest renewable polymer on earth.

Zhang said there is large interest in the application of cellulose nanocrystallites (CNC), which are the elementary units that construct crystalline cellulose from plants.

“My group has previously synthesized a new biocomposite material from CNC for small-diameter replacement vascular graft application,” he said. “The objective of this research is to synthesize new functional materials from CNC.”

Plant pathology

WSU Tri-Cities newsNaidu Rayapati, an associate professor of plant pathology at WSU’s Irrigated Agriculture Research and Extension Center in Prosser, is working with Emily Jordan, a science teacher at Chiawana High School, to study the gene sequencing and genome diversity of economically important grapevine viruses.

“The teacher will gain hands-on experience in molecular biology and state-of-the-art gene sequencing and bioinformatics technologies to elucidate genome diversity of the viruses for practical applications in vineyards,” Rayapati said.

“The experience will help the teacher introduce new concepts of scientific inquiry in the classroom to inspire students interested in pursuing careers in STEM fields,” he said. “We hope to pursue innovative strategies with the K-12 school systems in the Yakima Valley for strengthening higher education in STEM fields.”

Classroom application

The WSU professors are also working with the high school teachers to develop lesson plans, potential course projects and more based in the research they conduct at WSU.

“This partnership will strengthen both the high school program, as well as the research and college science program, by adding a new perspective to the research teach and new tools to use in the classroom,” Cooper said.
