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!

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.

Juan Camilo Riveros

Bogota, Colombia

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

Got a revelation on my first pint of Guinness and being from a country with only industrial lager for beer decided to start brewing my own. I studied culinary arts in Argentina and there also learned the basics of brew ing. After that the books of Palmer, Papazian, Talley, Daniels, Hieronymus, Bouckaert and Cantwell, and Michael Jackson were my sources. A lot of homebrewing came after that. Humanity and beer have a very close relationship most of the different cultures in the planet have beer whenever they are celebrating or mourning. It is comfort for a friend or just joy of being somewhere or with someone. Good beer brings us together and gladness our spirits.

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

Judging at WBC means a lot of different things for me. In a way is a validation of all my reading, tasting, and hard work in general. It is also an important way of learning from people more knowledgeable than me or from beer cultures that I am not so familiar with. In a more personal level there is a moment that comes from time to time when a table of judges just sync perfectly and complement each other, where knowledge is shared and we are able to do a great job. That moment is very satisfying. Last but not least, when I am judging beer I feel that each beer tells me a different story and sometimes you find exceptional ones that innovate and change the way that you look at beer as a whole.

Sebastian Hohentanner

Tokyo, Japan

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

I was born and raised in Munich, Germany, so good beer was always a given for me—available almost anytime, anywhere, especially in our beautiful beer gardens. However, while studying in Japan, I learned that this wasn’t the case everywhere. Searching for a good Bavarian-style hefeweizen in Japan started my journey into the world of craft beer. It led to a career in the Japanese beverage industry, supplying breweries with brewing equipment, ingredients, and education to create some of the best beers we have in Japan today.

In my daily work, I am truly grateful for the opportunity to connect the brewing culture of my birthplace with the brewing culture of the place I choose to live. Nothing brings people together like beer!

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 most prestigious and well-established beer competition—a model for beer competitions worldwide. Therefore, it’s an honor and a privilege to judge at the World Beer Cup. Judging beers with industry veterans and colleagues from around the globe in such a well-organized, professional setting creates a unique opportunity to continuously learn about beer and sharpen sensory skills. I especially appreciate the discussions with fellow judges during and after the competition. Everyone’s openness to share knowledge and experience, help one another, and enjoy beer in a friendly and collegial atmosphere is amazing. I hope to participate in and contribute to the World Beer Cup for many years to come.

Maria Sol Cravello

Buenos Aires, Argentina

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

While studying at university, I worked in a microbiology lab. I was fascinated by microorganisms and wanted to learn more about them. After earning my degree in food science, I was determined to find a job that combined microorganisms and food. How bacteria and yeast transform flavors and aromas was—and still is—impressive to me. Fortunately, I discovered the fantastic world of beer.

My first job after graduation was as sensory lead at the largest brewery in Argentina. Today, 12 years later, I still dedicate my career to educating and spreading beer knowledge and appreciation at every opportunity.

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 has been a dream of mine since I started my career. I remember attending Craft Brewers Conferences and WBC awards ceremonies, thinking, “Wow, will I ever be part of this huge event?” The day I received the invitation to judge in Las Vegas in 2024 was one of the best days of my beer career. I was so excited telling everyone about it that I almost forgot to reply to the email and nearly missed out on the competition!

The news was so big in my country that I was interviewed by the most important local newspapers about my experience as a judge representing Argentina. That’s how significant being a WBC judge is to me. 🙂

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. It’s a great opportunity for me to both contribute to the evaluation as well as make new friends and master my skills. 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.

Gad Deviri

Tel Aviv, Israel

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

It all started for me with homebrewing, which fed my soul. I started to import brewing supplies to the very young and small Israeli craft and homebrew market. I enrolled in courses at the Siebel Institute in Chicago and started teaching homebrewing and beer sensory.

Beer is a very interesting drink. It can be very ‘down to earth’ or a very complicated drink. It has so many shapes and shades. It’s never boring.

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

Judging in the prestigious competition in the word is a milestone in my professional life. It is an honor to be part of the team. Judging at this International competition gives me a broad perspective of the world of beer styles and tastes and is a rare opportunity to meet others from the industry.

Silvia De Tomas Ayllon

Lima, Peru

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

I am part of the second generation of a brewing family in Peru that started in 2003. My parents taught me the art of making beer when I was 9 years old, studying and learning from it. This is how I fell in love with that passion, with its community, and everything that revolves around it. Over the years I have founded projects such as the Latin American Craft Beer Cup, Peruvian Beer Cup, Brewmart school, Brewpub Cebichela and my Two Broders Brewery. I also became a beer judge in 2014, participating in multiple competitions in Latin America. Beer matters to me, because it is part of the story of my family, of my life and it has taught me a lot over the years. I feel respect, admiration and I work hard to share with others how important it is, that they learn to value it, but above all to understand it.

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

I always dreamed of being part of the World Beer Cup, ever since I was young I always admired everyone who was part of it, and the experience one must have to be chosen for this great competition. I always followed in detail each event organized by the Brewers Association, learning from it and using it as a reference for the Peruvian market.

I judge beers in this competition, because it brings together the best beers and breweries in the world into one place. The level of analysis and professionalism that exists in each tasting session is incredible. Since beers are of a high level, it allows you to have different points of view and understanding about the every beer. You get to meet judges from all over the world! This is a very reason important reason for me to be part of it, get to know different cultures, exchange ideas, they make me personally a better person every day.

I am very happy to be part of this great competition that marks important milestones in the history of beer worldwide.

Walter König

Bavaria, Germany

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

I’ve never done anything other than beer and music! I grew up on a farm in a small village in Bavaria. There was a princely brewery in this village that was founded in 1598. Our neighbor was a brewer in this brewery and I often visited him in the brewhouse. I was fascinated by this craft and quickly became enthusiastic about the profession. At the age of 15, I began training as a brewer and maltster in this brewery. After several years of practical experience as a brewer, my career path took me to the Technical University of Munich, where I graduated as an engineer in brewing and beverage technology.

In Bavaria in particular, beer is closely associated with traditions, festivals, rituals and everyday life. There are many different beer styles for every occasion and every season. Due to my background in agriculture, I am primarily fascinated by the beer raw materials malting barley, wheat and of course hops and the conviction that a good beer needs nothing more than three ingredients, nature and the skill of the brewer.

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

I would like the German beer styles to be interpreted and judged at the jury tables in the way they have evolved from their tradition. I also enjoy exchanging ideas with judges from other countries and beer histories and discussing other beer styles and trends in the brewing industry.

Every brewer who submits a beer to the competition is entitled to transparent and honest feedback on their beer. It is therefore important to me that well-trained and focused judges give each beer the necessary attention. The World Beer Cup offers optimal conditions for this thanks to its organization and the online-based evaluation system. And despite the concentrated work, there is still enough freedom and many opportunities to get to know each other and have fun.

Matthew Peetz

Colorado, United States

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

I started homebrewing in grad school while studying cellular repair using yeast as a model organism. My grad advisor was in charge of the Rocky Mountain Microbrewing Symposium and I was able to meet industry experts while volunteering at the event. I continued to work with yeast as a research professional at University of Colorado Denver before moving to the Brewing Science Institute. I used my expertise with propagating yeast to work in the biofuel industry before founding Inland Island with a co-worker. I have spent the last five years building my own business, Propagate Lab, which provides yeast for the brewing, distilling, and cider industries.

Beer is meant for enjoyment. It can transport you to anywhere in the world as you taste thousands of years of human experience and history. With hundreds of yeast, hop, grain, and other ingredient varieties, almost any flavor, texture, and color of beer can be produced for your enjoyment. You can pick apart the flavor, color, mouthfeel, and aroma. Or you can just slam down crushable lagers. That is what is so great about beer!

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

Beer is a wonderful combination of culture, history, art and science. Brewers work tirelessly to create something that the public can enjoy. Those that are masters of their craft should be recognized at the highest level, which is winning a World Beer Cup award. The brewers are serious about what they do and should be judged by knowledgeable and professional judges. I have 10 years of industry experience, lead sensory training programs at a local University, and have traveled extensively in Europe. I believe that I am well trained and passionate enough to make sure that every beer sample is being judged as it should be.

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.

I began my journey in the beer industry from a scientific perspective, initially focused on producing scientific knowledge. Over time, my path shifted towards science, technology, and education, particularly within the realm of sensory sciences.

The beer industry, with its complexity and diversity, offers an intriguing platform for exploration, innovation, and the pursuit of excellence. It serves as a fusion point where science meets craftsmanship, tradition merges with innovation, and artistry blends with precision. Beer holds significance because it transcends being a mere beverage; it embodies a rich tapestry of history, culture, and craftsmanship.

Beer matters to me because it represents a dynamic world where science and culture converge to shape a constantly evolving and vibrant landscape.

It’s not just a drink; it’s a catalyst for learning, sharing, and forging meaningful connections.

Flavio Boero

Genoa, Italy

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

When I was young I was fascinated by the fermentation of wine by following my father in his small production. In 1973 I had the opportunity to work for an Italian brewery named Poretti Industries. I started in the lab, and part of my job was collaborating with the lab manager in researching off-flavor in beer. At that time we were the only brewery in Italy that used gas chromatography to do basic research on the brewery sector. I also worked for this brewery when it was acquired by Carlsberg, but my passion for beer increased when I became interested in craft beer production in Italy.

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

I think the renaissance of beer started in the U.S. Right now, the World Beer Cup best represents the evolution of beer, and leads the beer movement around the world.
