World Class Judges

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

I started my beer career very early, at 19 years old, as a brewer. After more than 15 years in which I participated in the founding of the Argentine Brewers Association, wrote articles, made video tutorials and wrote a book, I decided to found my own brewery, Juguetes Perdidos. I have been an International Judge for more than 15 years and thanks to beer I have traveled all over the world and met wonderful people. Today I am 45 years old and my life is completely filled with beer, so much so that my children learned to say “aftertaste” before “dad.” If I had to define in one word what beer means to me, I would say it is “passion.”

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

I trained for many years to be able to enter the World Beer Cup as a judge. It is the highest level we can aspire to as international judges.

Judging at the World Beer Cup is a unique opportunity to learn from other judges, share time and experiences, represent my country, Argentina, and be part of the most important competition in the world of beer.

Juguetes Perdidos, my brewery, was the first one to get a Gold award for Argentina at the World Beer Cup!

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.

Francisco Montanaro

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

Working as a flight attendant for an airline, I managed to travel around the world and try local beers in over 60 countries! During my last years flying, things got serious, as a good friend of mine started homebrewing in his apartment and I used to assist during the brewing sessions (mainly with the BBQ). During that time we used to buy a lot of different beers without really knowing much about what to expect in each bottle/can. It was a fun way to start learning about beers. After a couple of years, things got serious and I’ve working in the beer industry for the past 10 years now. Beer is my day-to-day passion — couldn’t even imagine my life without it!

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’s an incredible way to learn with the best beer judges from all over the planet. It’s a really fun and delightful experience, such a privilege to be part of it, as well a lot of responsibility.

It’s a great way of connecting with people from all sides of the beer community, to recognize the creativity, talent and technical merits of all producers behind every single glass of beer we’re tasting.

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.

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

I really love the opportunity to meet new people who care as much as I do about this profession, and to reconnect with old friends. I enjoy testing my perceptions of beer and gaining new perspectives from other judges, as well as from the beers we judge. I also love the honor of tasting the best efforts of hard-working brewers.

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.

Dominic Charbonneau

Quebec, Canada

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

Like most brewers, I started as a homebrewer, and decided to offer more flavor to the people by starting my brewery. To do this, I needed to understand and know beer styles and taste them, so I studied and traveled to taste every style of beer. This led to earning Beer Judge Certification Program and Cicerone credentials, which now help me every day in the brewery.

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

Judging the World Beer cup is like judging at the Olympics. It is a huge competition where the best of the best are represented. The challenge of finding the appropriate beer for the style in every flight is incredible and a great training for developing my tasting skill, and of course to help brewers understand their product.

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.

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.

Amaey Mundkur

Connecticut, United States

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

I fell backwards into beer. I ran out of money while living in Australia and starting home brewing so I could continue to enjoy beer as a 21-year-old. I made a lot of bad alcoholic ginger beer before I learned to brew proper beer. People started buying my homebrew that I made out of my dorm room on the 11th floor of Howitt Hall at Monash University.

After I graduated, I didn’t want to move to Christmas Island in the South Pacific to study predatory ants that feasted on the migrating red crabs.So I picked beer.

Beer matters because it is art and love. It is an expression that is worthy of sharing. It matters to me because it engages with the very core of me, the scientist, the pedant, and the creative. Beer is about community — and as an immigrant from India (and the only Indian World Beer Cup beer judge — yes, out of almost two billion humans) who loves personal expression, it is where I belong.

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

I judge beer for a couple of reasons. It’s extremely important to positively impact beer quality. I have been in this industry for almost twenty years and have made beer on four continents. In that time, beer has grown, changed, and become what it is today. It is important to give positive feedback to all those brewers who aspire to be great, and I hope I can be part of that journey.

Judging at the World Beer Cup literally means the world to me. It is an affirmation of my achievements in the industry, as recognized by my peers who have kindly allowed me to judge with them, and to be part of an esteemed group of people that I can learn from. Hoarding information is selfish, while sharing it is selfless. And I hope to learn more.

What else would you like the world to know?

Besides beer, I love all the time I can spend with my wife and dog. I like hitting a little white ball around a large field (golf) and into a tiny hole. I love cooking and my family!

I have been working with beer since 1996. For me, it is a matter of constant research and knowledge. I enjoy beer in many aspects.

Being a World Beer Cup judge gives me a lot of experience, sharing knowledge with judges from other countries and tasting beers from different parts of the world in a professional context.

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.

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 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.
