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

After several career changes in my twenties—from being a photographer for a local Los Angeles weekly covering music and politics, to working as a CNN assignment desk editor, and then as a legal clerk at a high-powered corporate law firm—I found my passion in homebrewing, with the goal of one day opening my own brewpub.

Discovering my destiny and community within craft beer has been incredible, and I still can’t believe I get paid to do this.

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

I often tell aspiring beer judges that becoming a judge at the World Beer Cup can make you a better brewer and person. The experience involves interacting with fellow international beer judges, honing the skills of listening and being open to discussion. It’s a humbling experience that requires judges to set aside their egos, as we all strive toward the common goal of recognizing the best beers.

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

I started homebrewing in Chile in 2000 and launched my own craft brewery in Santiago, Tübinger, in 2007. I’ve been a certified BJCP beer judge since 2014 and have judged at the world’s most important beer competitions, such as the World Beer Cup, Great American Beer Festival, European Beer Star in Germany, Brussels Beer Challenge in Belgium, World Beer Awards in the U.K., Blumenau Beer Cup in Brazil, and others.

I’m a co-founder and the current executive director of Chile’s Independent Craft Brewers Association, ACI Chile, since 2019, which has over 150 members from all over Chile. We’ve been organizing the yearly Great Chile Beer Festival and its beer competition, Copa ACI. During the dark years of COVID-19, I made the most of the downtime to write a book about beer history, beer culture, and beer styles. I’m proud to say that it has been quite successful, with two sold-out editions since 2021.

Beer has been part of my life since my student days in Germany, and I feel that I learn more every year about this beautiful beverage. I love opening people’s minds to the wide variety of beers, and there is still much to be done in that regard in Latin America.

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 like being at the global center of beer experts, and it is always a pleasure and a great honor to share time, stories, and pints with the most accomplished brewers and beer judges in the world. This experience enables me to continue learning and improving my knowledge of beer tasting, new trends, and beer style appreciation.

It is also important for me to represent our relatively small country and emerging craft beer market at a global event and to spread the word about the increasingly vibrant Chilean beer market.

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.

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.

Ai Tani

Osaka-shi Kitaku Oyodonaka, Japan

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

“Almost 30 years ago, small-scale brewing began in Japan. At that time, imported German and Belgian beers were occasionally available in Japan. Small-scale brewing had begun, but there were few high-quality beers and few good brewers. I decided that I would grow as a professional and spread the word about the existence of high-quality beer in Japan. This is why I entered this industry.

Twelve years ago, I decided just acting as a judge was not enough to advance quality standards, so I started running my own bottle shop and beer pub, selecting good quality beer, and providing it to consumers while maintaining quality. Since five years ago, I have also owned a brewery, and while deepening my awareness of beer, I also improve brewing, sipping and serving skills, and support the management of breweries and restaurants.

Beer has a long history and has recently evolved from technological developments and scientific advances. From the current situation, where Japanese historical food and liquor culture is evolving through beer, we believe that we can find an opportunity to build a new beer culture in Japan.

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

Being able to judge at the World Beer Cup, the world’s premier competition, is a source of pride. It is a good opportunity to measure my judging skills.

It was also a great experience how the judges are organized at the World Beer Cup. I believe it is the best competition in the world. The fact that many Japanese have won awards has become a guideline for quality improvement for Japanese brewers. It is also a great place where you can exchange information with beer judges from all over the world.

I was able to talk about my role as a judge and my thinking about evaluation at a high level. I would like to take it back to Japan and use it to educate beer judges and give advice on the growth of the market.

Sao Paulo, Brazil

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

During my chemical engineering degree, I had the opportunity to intern at Grupo Petrópolis, a Brazilian company with 100% national capital. I enjoyed this experience and realized that the beverage industry fascinated me, though I hadn’t yet identified the area I connected with most. After graduating, I had the chance to return to the company, this time as a professional in the quality assurance department, focusing on beverage sensory analysis. It was then that I realized this area was the perfect fit for me, and I’ve continued my career in this sector with a great passion for what I do. Beer is important to me because it has helped me find and develop myself as a professional.

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

Based on my experience and training in sensory analysis and beer, I naturally set some career goals. One of them was to become an international judge, and in 2024, my opportunity arrived. I had the honor of being part of the sensory panel at the World Beer Cup. I feel fulfilled to have been part of a competition recognized worldwide for its excellence and quality. I learned a great deal during the competition and returned home with immense gratitude.

Lotte Peplow

Greater London, United Kingdom

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

I’ve been in the beer industry all my career but initially on the periphery, and I came to it through the PR and marketing route. As the craft beer world grew so did my interest and passion for the subject. I was lucky enough to begin my long relationship with the Brewers Association back in 2006 and I gradually took on more responsibility. My role widened until in 2019 when I was appointed American craft beer ambassador for Europe. It’s an honor and a privilege to work for the Brewers Association and I’m incredibly proud to represent them either when traveling overseas or at home in the UK.

For me, beer is not just a career but a way of life. I love the wide variety of flavors and aromas found in beer. It’s super versatile and makes the perfect food accompaniment. I love the beer community and the people who make this industry special. Everyone is friendly, welcoming, and united in a shared appreciation of this beautiful beverage. It’s a uniquely collaborative space and I count myself very lucky to be associated with some of the most talented brewing minds in the industry.

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

Judging in the World Beer Cup is the pinnacle of my beer journey and the gold standard in beer judging. It’s like competing at the Olympics! The quality of the competition is second to none — from the world class quality of the entries to the high standards of the judges and the professional, smooth-running organization behind the scenes. Of all the competitions I’ve judged around the world, the World Beer Cup is the biggest, most prestigious, most international, best-organized and most professional of them all — in my humble opinion, of course!

Being selected as a judge for the World Beer Cup is a huge honor and fills me with pride. I love judging because it focuses my mind on everything I’ve learned about beer and brewing. Much like an Olympic athlete, I have to be at the very top of my game and that’s an exciting and thrilling prospect.

I have only judged one World Beer Cup so far (2023 in Nashville) but was completely blown away by the standard of entries, quality of the judges, and organization of the competition. It was an enormously rich and rewarding personal experience and one I hope to repeat again soon.

What else would you like the world to know?

I play hockey (that’s field hockey to my American friends!) for a Club in southwest London and have done for many years. It’s great fun, a chance to run around and blow away the cobwebs before a beer in the bar afterwards. Last season we were undefeated and won promotion to a higher league. This season may be different! I’m married with three grown up children and one very lively dog.

Masafumi Morita

Nagano, Japan

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

It was 20 years ago when I had my first taste of English Pale Ale and was shocked. It was the moment I discovered the diversity and richness of flavors in beer. From there I went on to drink all kinds of Japanese craft beers and eventually had the opportunity to work for the brands I loved the most.

I think beer is a very important beverage because it is one tool for living a relaxed life, and it promotes community and connection.

Craft beer is also a great new form of industry. The spirit of working together to create a market, rather than each brewery competing for it, is the most important aspect of craft beer. It feels like it represents an improvement over capitalistic economic activity. That’s why I love working in this industry.

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

I love the craft beer industry and want to contribute my bit to it. The judging sessions give me tips on how to improve my brewing, and I get to have a great time with my judge friends from around the world — it’s an irreplaceable opportunity for me.

The World Beer Cup is attended by some of the best brewers, journalists, and consultants, and getting to know them and sharing new ideas and information is also a great experience. I feel very fortunate to have been a part of this effort for over 10 years. Without this experience, our beers would be of a lesser caliber today.

What else would you like the world to know?

Beer is just a beverage and has no power to heal injuries or illnesses. But we are born in really difficult times, with a lot of stress, and drinking a good craft beer is one oasis. I also feel that the craft beer industry is taking a more democratic, artistic, and organic approach to things. I am hopeful that it will gradually make the world a better place. I encourage you to seek out craft brewers in your area who have a great spirit. And if you can relate to them, please support them.

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

It all started in 2013 when I joined Heineken Brau Union Austria as a brand manager looking after three big beer brands in Austria. One year later the brewery sent me to get an education as a beer sommelier and it triggered my passion for beer. Beer is the most versatile drink in the world and I am still curious about it.

It is a very special contest to judge as one of a few of the Europeans and it’s a great honor to be part of it.

I am the first Austrian female to be invited to judge in the World Beer Cup. 🙂

Steve Gonzalez

Californa, United States

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

I’m a decent scientist with a deep love of history and my family has a culinary background, from French to Mexican cuisine. I took a break from studying in college to homebrew with some friends and saw all of those things in beer: science, heritage, anthropology, food presentation, and preparation. A natural fit, and a perfect way to step away from physics and organic chemistry for a few hours.

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

It keeps me current, I get to taste things I have never tried before with no preconceptions, no biases. All of that makes me a better brewer!

Michael König

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

In 2011, I started as a beer blogger out of love for this topic. At this point in time, craft beer also took off in Germany. Through my blog I had built up a large network with many breweries in a short time. In 2013, I became a beer sommelier at Doemens and in 2014 I switched full-time to an online shop for craft beer. Since 2016 I have been head beer sommelier or brand ambassador for Maisel & Friends at the Gebr. Maisel brewery, a dream job. Beer is my hobby, passion, and profession … my life. I love trying new beers, talking about beer, and discovering beer every day.

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

The World Beer Cup is the best beer competition in the world. Sitting at the table as a judge and talking about beer with many well-known beer personalities is an honor and fills me with pride. As a judge at the World Beer Cup you determine the best beers in the world. How cool is that? It is the best job in the world.

Kevin Ashford

California, United States

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

I discovered craft beer in college while bartending at a restaurant in Harrisonburg, VA. We had about 100 rotating bottles and cans, and I was able to try one at the end of each shift. I was amazed at the variety in beer, and became fascinated by its history and regionality. After getting my degree in international affairs, I discovered I really just liked people and wanted to learn of ways to bring them together. Beer seemed like a good way to do that. I decided to forego my opportunity to work on Capitol Hill in D.C. to fall back on bartending and learn more about beer. One of my regulars at this bar in Maryland was a seasoned brewer at our midsized regional brewery. When I asked him one day if any floor sweeping jobs were available, his ears perked up. He set me up with an interview with the Brewmaster and I was hired on the spot. I fell in love with beer making, and the rest is history. Beer matters to me because it has withstood the test of time. It is a champion of bringing us all together.

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

I judge at the WBC to honor brewers past, present, and future. I believe consumers have the right to enjoy high quality beer, and WBC challenges brewers to provide beer of the highest quality. Judging at the World Beer Cup is so important to me, because I really care about beer and its history. I want to ensure that classic styles remain abundant for generations to enjoy. It is an honor to adjudicate beers from all over the world and share the enthusiasm for the past time of beer making.
