How did you get into the beer industry? Why does beer matter to you?

My interest in brewing began in college when I took a semester off and stayed with friends in the Bay Area, one of whom had taken up homebrewing. I helped him with a few batches and then dove into the deep end when I returned to school at the University of Kansas, where a homebrew supply shop had just opened in Lawrence. Many batches later, with a bachelor’s degree in art history in hand, I moved to Seattle hoping to land a brewing job. That first job paid me $6 an hour. Needless to say, I wasn’t into beer for the money—I was into it for the people, the community, the creativity, and the camaraderie.

I was fortunate to have amazing mentors, peers, and colleagues during my time brewing at Pike Brewing Company in Seattle, and later at Free State Brewing when I returned to Lawrence. Beer matters to me—or I should say, good beer matters to me. To borrow the words of Brother Epp of Capuchin Monastery in Munjor, Kansas, written in 1906 during Prohibition: “Because, without beer, things do not seem to go as well.”

Why do you judge at the World Beer Cup? What does judging at the World Beer Cup mean to you?

Every time I judge the World Beer Cup, I learn something new and gain perspective from a diverse group of judges who may not speak the same language I do on a daily basis, but certainly speak the language of beer. It’s great to judge with German judges in German beer categories or Belgians in Belgian beer categories and get their perspective on the nuances of a classic style originating from their home country. It’s equally interesting to hear the perspective of an Argentinian or Japanese judge on these styles and learn more about the growing beer culture in their countries.

I’ve made new friends that I look forward to visiting in their home countries someday and seeing when they visit us during the World Beer Cup. Good beer brings good people together.

How did you get into the beer industry? Why does beer matter to you?

After helping to open a backpackers hostel and bed-and-breakfast in 2012 in Quito, Ecuador, we quickly saw a demand for craft beer. We had guests from all over the world passing through, and many often asked where they could get a good pint. At that time, the only options available were the typical commercial national lagers that small Latin American countries have. Having just graduated from the University of Oregon, we were very familiar with the amazing options local craft beer had to offer, so we started brewing in Ecuador in hopes of serving great beer to our guests and introducing our local friends to the culture of American craft beer.

Why do you judge at the World Beer Cup? What does judging at the World Beer Cup mean to you?

It’s an honor to judge at the World Beer Cup. Judging there is an opportunity to give back to the brewing community I hold so dear, and it allows me to test my skills against other judges with different levels of experience and diverse backgrounds. There’s always something to learn as a judge, and even more so when you are paired with some of the other great people at WBC.

Craig Thomas

California, United States

How did you get into the beer industry? Why does beer matter to you?

My first brewing job was meant to be a stepping stone into distilling. However, as I pursued my master’s in brewing and distilling at Heriot-Watt University, I began appreciating beer more and more. To me, it felt like a more experimental, exciting, and forward-thinking craft. The diversity of ingredients, techniques, and historical traditions delivered a broader, more compelling story of flavor and experience than distilled spirits did. There is so much to learn, and each moment of learning is aided or reinforced by sensory experiences that have created very impactful memories for me.

Since graduating in 2014, I’ve done my best to shape my career path by putting myself in situations where I can absorb knowledge from people with different types of expertise. I’ve had the privilege of traveling the world tasting beer while working with Bill Simpson and AROXA. I’ve brewed with some of the best at Firestone Walker Brewing Company, tested my practical and theoretical sensory knowledge as part of the ASBC Sensory Subcommittee, and explored beer dispense in order to earn Master Cicerone. Now, at Abstrax Hops, I’m reevaluating everything I thought I knew about beer. New frontiers never end!

Why do you judge at the World Beer Cup? What does judging at the World Beer Cup mean to you?

There is no other place where so many diverse, knowledgeable, and experienced people gather to taste and talk about beers and beer styles. What better spot to challenge preconceptions, discuss new techniques, and discover new trends? Furthermore, the competition brings in a plethora of world-class examples across so many styles. It is the only place where one can repeatedly experience technical precision and artistic expression in equal measure—sometimes at the same time. Competitions like the World Beer Cup are outlets where a brewer’s intent can be fully grasped and appreciated, as these beers are labors of love, often produced fresh and free from the constraints of distributor deals, consumer preferences, cost-of-goods quandaries, and dispense dilemmas.

Agus Blanco

Madrid, Spain

How did you get into the beer industry? Why does beer matter to you?

My journey began behind the bar, serving patrons and forging connections with both the bartending team and the final drinker. This experience sparked a passion for understanding spirits like whisky and, especially, beer. I saw myself as a bridge between the consumer and the producer, eager to be the door that welcomes people into the world of flavors.

For over a decade, I’ve continuously honed my communication skills in the realms of beer, whisky, and now mezcal. My passion evolved into expertise, allowing me to train both brewers and judges at Lúpulo Digital’s tasting gym. I help them hone their sensory skills to craft and appreciate exceptional beverages. My focus lies in optimizing flavor and aroma profiles for breweries, ensuring their beers capture consumer hearts (and taste buds!).

In 2023, I had the honor of judging prestigious international competitions across the globe, expanding my knowledge of diverse beer styles and trends (Brazil, Germany, South Africa, Belgium, Spain). Looking ahead, I’m excited to continue this journey in 2024 (U.S., Italy, Mexico, etc.).

Why do you judge at the World Beer Cup? What does judging at the World Beer Cup mean to you?

Judging at the World Beer Cup was a challenging yet enriching experience. Exchanging knowledge with fellow judges, from all corners of the globe and brewing generations, is truly special. The Brewers Association’s legacy as a craft beer revolution leader makes connecting with these judges even more meaningful. The vast knowledge and diverse perspectives at the WBC have challenged and broadened my understanding of beer. This event highlighted the ever-evolving world of beer, a community brimming with creativity and pushing boundaries. I’m grateful for this experience and excited to see the BA continue fostering innovation and inspiring future generations of beer lovers.

Kathia Zanatta

How did you get into the beer industry? Why does beer matter to you?

After finishing my food engineering degree in Brazil, I followed my love for beer. I landed an internship at Paulaner Brewery in Germany in 2005, where I delved into the world of brewing and embraced the country’s diverse beer culture. Upon my return, I transitioned into a role at a brewery in Brazil, where I honed my skills over a five-year period in areas such as quality control, research and development, and laboratory analysis. In 2008, I embarked on a journey to Germany for the Beer Sommelier course, marking my entry into Brazil’s burgeoning craft beer scene.

Equipped with this expertise, I began organizing beer events. By 2010, I co-founded Instituto da Cerveja, an educational institution dedicated to the art of beer, and since then I have been fully committed to studying (including a brewmaster course in 2011), impactful teaching, hosting beer and food events, and consulting.

Why do you judge at the World Beer Cup? What does judging at the World Beer Cup mean to you?

I have been participating as a judge in beer competitions since 2009, consistently enjoying the opportunity to expand my knowledge of beer, sensory analysis, and the market. It’s not only a chance to connect with new colleagues, but also an opportunity to support breweries by engaging in discussions about their beers and providing valuable feedback.

Walt Chleva

Colorado, United States

How did you get into the beer industry? Why does beer matter to you?

I started off in the beer industry by working part time at my local homebrew store and wanted to take my brewing to the next level. I was able to get a position as a part time brewer for the brewery attached to the homebrew store and the rest is history.

Beer matters to me because from such a rich history comes the continued refinement and creation of a beverage that spans the world over. Beer has been enjoyed all around the world for thousands of years and poured into all sorts of vessels with many ingredients. Enjoying beer makes memories and is an experience that I feel blessed to be able to partake in, especially at this time in world history where the beer quality is at its peak.

Why do you judge at the World Beer Cup? What does judging at the World Beer Cup mean to you?

I judge at the World Beer Cup because I have been in the beer industry for over 15 years and have loved seeing the increase in quality over the years. Brewers have been putting more effort into making quality paramount in the more recent years, making this last year’s judging experience the best one yet!

Judging beer at the World Beer Cup puts my skills to the test and allows me to continue my never-ending journey of sensory knowledge as I learn more each time I judge from some of the best in the world at determining the minute compounds created during the mash, the fermentation, or the packaging process.

Fernanda Ueno

São Paulo, Brazil

How did you get into the beer industry? Why does beer matter to you?

I began my brewing journey in 2009 at Cervejaria Colorado in Brazil, starting as an intern and becoming head brewer. After earning a degree in food engineering, I completed the Master Brewers Program at UC Davis in 2015. I then led innovation projects for AB InBev’s craft breweries across South America and Europe.

In 2021, I moved to Europe to manage brewing and quality for ABI’s craft brands—including Camden Town, Bosteels, Birra del Borgo, and La Virgen—as well as co-packers and Beyond Beer products, until 2024.

Throughout my career, sensory analysis and beer judging have been part of my daily work. I’m passionate about experimenting with new ingredients, flavors, and techniques, exploring not just beer but also beverages like sake and coffee.

I’m also co-founder and brewmaster of Japas Cervejaria, a female-owned gypsy brewery blending Japanese and Brazilian influences. We brew and distribute our beers in Brazil, the U.S., and Taiwan, using beer as a creative way to honor our heritage.

Beer continues to teach me and connect me with amazing people every day—and I’m proud to give back to the industry that inspires me so deeply.

Why do you judge at the World Beer Cup? What does judging at the World Beer Cup mean to you?

Judging at the World Beer Cup is both an honor and a way for me to give back to the brewing community that has shaped so much of my life. It’s a chance to support brewers by providing thoughtful, constructive feedback, and to celebrate the creativity, diversity, and technical skill that go into every beer. With a background in brewing, sensory analysis, and innovation across different cultures and styles, I see judging as a unique opportunity to keep learning while also helping to uphold the highest standards in our industry. It’s incredibly rewarding to be part of such a prestigious event that brings together passionate professionals from around the world to share knowledge, elevate beer quality, and inspire one another.

Jason Macias

Pennsylvania, United States

How did you get into the beer industry? Why does beer matter to you?

After graduating with my MBA in finance from Drexel University, I was conflicted. Should I accept just ‘any’ job where my education and skills would be rewarded with a salary, or should I build on my educational foundation with hands-on skills in a unique industry that I was interested in learning more about — which was brewing.

My interest in brewing began as a homebrewer and was fueled when I began working as a server at a brew pub while attending college which introduced me to brewing on a micro scale — larger than home brewing but smaller than ‘big beer.’ My first industry job was as an assistant brewer at an upstart brewery in the quiet suburban outskirts of Philly which was initially perplexing to my family until they heard me share stories of my first few weeks and they knew I found my passion.

Eventually my education caught up with me as I worked my way out of the brewery and into various sales roles, starting with beer then raw materials (hops, malt) and eventually printed and brite aluminum cans, where I happily work currently with the Zuckerman Honickman packaging team.

Why do you judge at the World Beer Cup? What does judging at the World Beer Cup mean to you?

The process of judging beer allows me to tap into my sensory skills, which I was mostly unaware I possessed until a few years back when I became a Beer Judge Certification Program judge and exam administrator for my local homebrew club. Having been educated in marketing during my undergrad years, I was well aware of how branding, labels, and packaging can impact consumer demand and sales. To completely put that aside and focus only on the actual beer was fascinating!

Beer styles are historical stories of a time and place where they originated. They offer glimpses into that time when you worked with what the land offered and played the hand you were dealt. Brewers played their hand across the globe creating the dozens of beer styles with countless attributes and characteristics that we have today. This is in addition to the story your senses can tell you about a specific beer sample’s journey into your sample glass.

The World Beer Cup represents the pinnacle of judging opportunities for me and I’m so thankful and proud to be a part of this beer judging community and engage with such amazing and interesting people from around the world.

How did you get into the beer industry? Why does beer matter to you?

In the summer of 2005, I found myself packing boxes and sweeping floors at a local brewery — and I was hooked!

The beauty of beer and brewing is that it can be as complicated or as simple you make it out to be, and finding that happy medium is up to each and every brewer. There are endless wormholes to seek knowledge and solutions, and continuously evolving techniques, equipment and ingredients. But at the same time, the brewing process is still timeless and logical. Good beer is good beer, no matter how you get there!

Why do you judge at the World Beer Cup? What does judging at the World Beer Cup mean to you?

Judging at the World Beer Cup allows you to meet people with different backgrounds in the beer industry from all over the world. It’s engaging, exciting, and often challenging. And it gives you an unrivaled snapshot of the current state of beer — from a quality standpoint, to trends and experimentation, to observing and developing beer style parameters.

Vasilios Gletsos

Vermont, United States

How did you get into the beer industry? Why does beer matter to you?

I was a puppeteer, touring around performing and started discovering classic beer styles from around the world. Also, I was really DIY oriented and fell in love with making beer at home. I got really into it after leaving Vermont and moving to Oregon, where I soon made the crossover into commercial brewing. Beer is deeply woven into the fabric of human social, cultural, scientific, and agricultural life. I love that about it and also how it stimulates my mind body and heart.

How did you get into the beer industry? Why does beer matter to you?

I started to brew beer 15 years ago. My first contact with independent and craft beer was in Bratislava when I visited a brewpub. Beer is all my life. My passion. I can’t imagine living without beer.
