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

I started homebrewing in 2006 and in 2013, with some friends, started a commercial project so we could drink the beers we wanted. I left my aeronautical engineering job in R&D to work and live from beer (or at least try to, hehe).

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

It’s a great pleasure to judge beers, share experiences and knowledge with people from all over the world. Each time I travel thanks to beer I feel rewarded in many ways—friendship, pleasure, new ideas, knowledge. The World Beer Cup is probably the biggest opportunity to experience all this.

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

I studied my undergraduate degree at the University of Colorado, Boulder. There, I was able to experience the craft brewing scene, but my true inspiration for brewing started during a study abroad year in Regensburg, Germany. I fell in love with lager beer and German brewing traditions. After returning to finish my studies, I started homebrewing. That accelerated my interest in beer and brewing, after which I applied and studied at the Technical University of Munich in Weihenstephan. After graduating, I started working with the world’s largest hop supplier, BarthHaas, as a technical manager. My passion lies in the tasting and technology of beer. Hops as a raw ingredient are the core of my passion. The composition, aroma, cultivation regions, and the individuals involved in the hop industry are central to my passion for beer.

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

I judge for many reasons: Meeting with beer industry colleagues, debating beer and beer styles, and experiencing the quality of beer in the market. The most interesting categories for me are all hoppy styles, but also the experimental categories where a brewer’s imagination can run wild.

First and foremost though, the World Beer Cup is for brewers and their customers. Therein lies the value for everyone in the industry and the most important reason why all the judges, breweries, and beer consumers should praise one of most important beer events in the world!

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

I entered the beer industry through an internship opportunity for QA and lab work. This was shortly after my first ever craft beer: a classic American pale ale, that completely blew me away with the complexity and delicious flavor craft beer could offer. As a microbiologist and anthropologist, my skill set seemed perfectly matched for the brewing industry. The love for the sensory sciences was a natural progression during my tenure in the industry because at the end of the day, beer is intended to taste cohesively good, which is something analytical data can’t always demonstrate. Beer has been a collaborative effort for millennia and I am excited by the contributions I can offer to encourage growth throughout the industry.

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 to expand my knowledge and palate for international classifications and flavors. I judge to meet fellow judges and learn from their wide range of occupations, experiences, and sensory backgrounds. The World Beer cup judging opportunity allows cultural divides and geo-political barriers to be loosened allowing for equal trade of beer enthusiasm and expertise. Bonus: Critically evaluating beer and diving deep into what four simple ingredients can provide and honoring our industry peers creativity is simply fun and rewarding!

What else would you like the world to know?

On average, 75% of the beers we taste throughout judging are good beers. Just because you don’t win an award doesn’t mean you aren’t making great beer. Keep up the good work brew crews and let’s craft beer thriving!

Bruna de Oliveira

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.

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.

Matt Johnson

South Dakota, United States

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

After homebrewing for a few years, I decided to become a professional brewer in 1997. I quit my job and went to brew school. I got a job as a brewer right out of school and never looked back. I was lucky enough to brew through the meteoric rise of craft beer, and I’ve enjoyed it the entire way. I worked my way up from brewing at a few brewpubs to being the brewmaster of brewery operations at a mid-sized brewery in San Diego, producing 85,000 barrels a year at our peak. Along the way, I built eight small breweries and have been a member of the Hop Quality Group, a voting member of the Hop Research Council, a member of the MBAA National Technical Committee, and the BA Brewpub Committee.

This industry is very big yet very small and collaborative, and I’ve enjoyed being a part of it. I will continue to be part of this great group of brewers and collaborators.

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

I became a judge for the simple reason that I wanted to learn more about beer styles and what it takes to brew them. Being able to taste and give opinions on beers for the World Beer Cup is a great learning experience. It also helps create friendships within our industry. Judging the WBC, one of the best beer competitions in the world, is an honor and a privilege for anyone. It’s a way to share my industry knowledge with other brewers and judges. I love it because it also allows me to continuously learn more about our industry and the trends happening within it.

Jose R Ruiz

Chih, Mexico

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

I started homebrewing back in 2001 and then moved for work to live in Michigan, there I met some brewing friends that were also Bee Judge Certification Program judges. They taught me how to brew all grain batches and then I took a course to become BJCP Certified. In 2008, on returning to to Mexico I wanted to open up a microbrewery, but I found out that there were no suppliers for ingredients in Mexico. I started looking for suppliers that were willing to have a new distributor in Mexico and that is how I set up Micervesa, the first brewing supply company in Mexico. After that I was invited to organize the first BJCP beer competition in Mexico, since I was the only BJCP Certified judge at that time, and that is how Copa Cerveza Mx started and became the most important Beer competition in Mexico.

Beer matters to me because I see it as a social drink that unites people and countries. Beer is one of the few things countries have in common as a drink, but of course with a great diversity of styles. Beer is fun and it is best shared with friends.

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

Being a judge at the World Beer Cup is a tremendous honor, as it allows me to participate in the most prestigious beer competition worldwide. It is a great opportunity to meet new beer judges and share and learn from their experience, and explore the beer culture from their countries and cities. It is also a great responsibility to judge and select the best beers on the table that will be given awards, knowing that they mean a lot for each brewery.

I think beer competitions are a great motivation for brewers to do their best effort and keep brewing excellent beer, and this elevates the overall beer culture and experience to the end consumer.

Satoshi Murabayashi

Tokyo, Japan

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

Twenty years ago, in Japan, I did not have a chance to taste the diversity of craft beer. On a business trip to the United States, I was totally shocked by the quality, appearance, aroma, and flavor of craft beer. After that experience, I joined the Craft Beer Association and realized that education is important to understand the value of beer; that the quality of beers are critically important for better moments; and that collaboration among global associations and competitions is so important. I am now contributing as a teacher and competition manager for the International Beer Cup in Japan and the Japan Great Beer Awards.

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

My first World Beer Cup was in San Diego in 2012. I wanted to contribute to this industry by tasting great beer and giving comments for their innovation. As a person from Asia, I would also share my local expertise with beer and judges here. In addition, I wanted to experience a world-class competition for learning and improving our competitions in Japan.

Shaun O’Sullivan

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.

Marek Kaminski

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

I have been working in the beer industry since early 2014, and later that year I co-founded a Polish craft beer brand, Browar Kingpin, where I have also served as brewmaster since 2018. I am a well-traveled international beer, cider, and mead judge with experience at the World Beer Cup, European Beer Star, Brussels Beer Challenge, Birra dell’Anno, International Beer Cup Japan, Concurso Brasileiro de Cervejas, and many other competitions. I have been the co-founder and president of the Polish Craft Brewers Association since 2018, and I also serve as an organizer, proctor, and grader for BJCP Beer, Cider, and Mead Judge certifications. Additionally, I am the BJCP EMEA Regional Director, a WSET Certified Educator for Award in Beer qualifications, a contributor to periodicals, and I run beer education classes and regular tasting events.

To me, beer embodies a rich blend of history, craftsmanship, and creativity. It’s a medium for exploring flavors, places, and stories, fostering communities, and celebrating cultural traditions. The art and science of brewing continually inspire me, offering endless opportunities for personal development and enjoyment.

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 it is the largest and one of the most prestigious beer competitions in the world, where I get to meet many great beer professionals and taste some of the best beers in the world.

To be a judge at the World Beer Cup is to be part of the judging elite and to have my competences in the field recognized.

Carlo Graciano

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

I started home brewing in 2009 and fell in love with beer industry. I co-founded my first brewery in 2014, Santo Domingo Brewing Co. We started small and grew to a 10bbl system. I was the COO overseeing the brewers. In 2016, I co-founded Cerveceria Punta Cana, and we started importing our flagship beer, Canita, with the intention to gain market to be able to start with a bigger brewery. I sold SDBC in 2020. Our first locally brewed Canita came out April 2021, that year we brewed 1,400 HL and we have grown to almost 24,000 HL a year.

I started my formal beer education in 2018 with the Cicerone Certification Program and in 2019 obtained the Certified Cicerone level and in 2024 the Advanced Cicerone level.

I started judging beer in 2019, and been traveling to beer cups every year after the pandemic to Colombia, Mexico, Brasil, Argentina, and the World Beer Cup in 2024.

Beers is not only a job for me. It is a way of life, and traveling to different beers competitions has become my way of meeting new people and seeing new places.

Judging at the World Beer Cup means judging the best beers in the world with the best judges out there. It means that at each table you share feedback with judges with vast experience in the styles being judged.

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.
