World Class Judges

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

I entered the world of craft beer in 2013 by opening Malta’s first craft brewery. The beauty of making craft beer is that you can experiment with many styles, and we do, using as many local ingredients as possible. In 2016, we brewed the world’s first Gose using caper flowers as dry hopping and sea salt from local cliffs. We also invite the world’s leading breweries to Malta, combining ingredients from their countries with our local ones.

The philosophy of my brewery is to use the best machinery available on the market to ensure consistency while still producing unpasteurized beers. I believe it is impossible to achieve this goal without technology.

Being a judge at the World Beer Cup is a great thrill and a point of pride to be on the panel with the best judges from around the world. Ever since I founded the brewery, the World Beer Cup has always been a milestone. It is the most prestigious beer competition in the world, and representing Malta for the first time in this competition is a great privilege and honor for me.

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

My journey into the beer industry began as a hobby that eventually grew into a passion for both academic and craft brewing. As one of the first certified judges at the time, I opened a craft brewery and pursued a Ph.D. in the field, all while actively judging beers. These experiences allowed me to combine my love for brewing with my scientific curiosity. Over time, my interest in fermentation science deepened, leading me to focus on beer evaluation and sensory analysis. Today, I lead research projects at Fermentis, where I continuously explore the complex dynamics of yeast, fermentation, and flavor—an area that remains both challenging and rewarding in my career.

Beer matters to me because it represents much more than just a drink—it’s a blend of science, culture, and craftsmanship. With more than 15 years of experience evaluating beers and examining the intricate relationships between microbial dynamics and flavor expression, I have gained a profound appreciation for the creativity and precision that brewing requires. Beyond its technical aspects, beer connects people and tells a rich story of tradition and innovation. Being part of this ever-evolving industry is incredibly rewarding, and I feel fortunate to contribute to its growth and development.

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 me to contribute to the global beer community while applying my expertise in sensory analysis and beer evaluation. With more than 15 years of experience in the field, I’ve developed a deep understanding of the nuances in beer styles and flavor profiles, which I bring to the judging process. It’s also an opportunity to engage with other experts, share knowledge, and help maintain high standards of quality and innovation in the industry.

For me, judging at the World Beer Cup is both an honor and a responsibility. It’s a chance to be part of one of the most prestigious beer competitions in the world, where brewers showcase their passion, creativity, and technical skill. It also means helping to uphold the values of fairness and excellence in beer production. Personally, it’s a meaningful way to stay connected with the global beer community and to celebrate the diversity and craftsmanship that make the industry so vibrant.

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.

Julia Herz

Colorado, United States

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

When I was little, I had a soap and perfume collection. My dad traveled for work, and he’d bring back soaps, while my mom would bring perfume samples. I would smell them, feel the texture, and consider the shapes, colors, and ingredients. I also paid attention to my dad’s imported beers in the fridge and the food my mom was cooking. Based on aroma, I’d try to guess what was for dinner while I was upstairs in my bedroom. That was all the stage I needed to become a judge.

When I moved to Colorado, I had been homebrewing and started to become interested in what judges were doing. The bottom line is that I followed my interests and worked to learn sensory techniques about hedonics and beer styles. To me, beer is the most incredible beverage to judge because it is limitless in ingredient possibilities. Judges are instruments for what we perceive, and our job is to tap into what we sense, relay that back to the entrant, and share where it meets or misses the style guidelines—kind of like a lawyer interpreting the law. 😊

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

Working to the level of being accepted and invited back to judge the World Beer Cup is a career highlight. Every time I judge, I learn and grow, and the WBC is unique because it has the most robust collection of international beer judges of any competition I can point to. Judging with peers from the same country is different from judging with judges from around the world. We help each other shed more “style bias” when judging from different cultural lenses. Hands down, the WBC is *the* judge invitation to snag. I like to tell new judges the only way to get invited is to put in the work, study, taste, brew, and apply.

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.

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

I was born into a brewing family and had no chance of avoiding beer, but fate has been damn good to me.

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

It is the international encounters — around a table, over evenings and days with tasters from all over the world, that is the World Beer Cup.

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?

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.

Luc De Raedemaeker

Brussels, Belgium

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

‘Beer and life: If you have to eat and drink anyway, you might as well enjoy it.’ This is an important rule of life that I learned growing up in Brussels, where I developed an appreciation for the offerings from the Zenne valley, particularly the Geuze and Lambiek. I acquired my taste for beer as a student bartender and my expertise grew as I trained in Belgium and around the world. I am now a lecturer in zythology and chief editor of Bier Grand Cru. My first book, The Belgian Beer Book, has been hailed as the perfect guide to Belgian beer and beer culture. I am a regular speaker at food and beer festivals all over the world. I am also the co-founder and director of the Brussels Beer Challenge, a prestigious international beer competition.

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 a chance to be part of a global celebration of beer, contribute to the industry’s growth and quality, and gain personal and professional enrichment through the experience. It holds a special place in my heart.

Dana Johnson

Colorado, United States

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

Like many, I got into the industry after falling in love with home brewing. For my 30th birthday, I was given a homebrewing kit and (of course) Charlie Papazian’s “Complete Joy of Homebrewing” book. This was prior to the internet and my first batch or two had a very steep learning curve, but I was hooked. Five years later, I knew I didn’t want to start my own brewery but saw an opportunity selling cleaning, sanitizing, and process aids to the industry. I’ve been doing it ever since and couldn’t be happier.

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

I’ve been judging at the Great American Beer Festival (GABF) since 2015. When the opportunity to judge at the World Beer Cup presented itself a couple of years ago, I jumped at the chance. The World Beer Cup is open to breweries all over the world, not just the US. The WBC is one of the most prestigious beer competitions in the world with some of the best judges in the world. It is interesting to judge with people from across the globe and is very educational. I am extremely honored to be included as a World Beer Cup Judge and to know that we are all very committed to doing our very best, each and every round and awarding medals to the best beers in the entire world.

Marco Malaga

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

I was born and raised in Lima, Peru. At 15 years of age, a teacher at my high school asked all students what profession they wanted to pursue as grown ups. My answer was “I would like to brew beer.” My teacher replied in disbelief: “And what do you have to study to become a brewer?” My answer was, “I am not sure but I will find out and do it.” My main inspiration was realizing how beer and brewing was an inherent part of society since ancient times. I was later gripped by the science, engineering, and artistic sides of brewing. I started brewing at age 19, graduated as a food engineer at age 23 and have been brewing continuously for 32 years. Beer has allowed me to make a living, travel all over the world, and be part of the amazing world beer community.

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 the utmost honor for a beer professional. Being able to taste the best beers in the world, side by side, and discuss them with some of the most knowledgeable beer professionals in the industry, is an absolute experience. Beer is continuously evolving and the WBC is certainly a place where you see that evolution. As a brewer it helps me understand where the industry is heading and how the boundaries of quality keep getting raised.

Nicholas Galton-Fenzi

Western Australia, Australia

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

I was a keen learner, and I started homebrewing at 17. My first batch of beer (kit and kilo) had very poor temperature control and showed a lack of brewing understanding on my behalf … It was absolutely terrible. From then on, I have tried to learn as much as I can about beer, the industry, the ingredients, and the people involved. This journey has taken me through 23 different countries and I have now been involved in over 50 breweries worldwide.

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 wish to share what I have learned within the industry. I do it so I can provide my feedback, where I can, and further learn, for myself, about beer styles. I get the opportunity to meet with fellow judges who can also provide additional feedback on the style of beer that is being judged.

What else would you like the world to know?

This industry is rapidly changing, with the amount of additional science and information that comes through on a daily basis. A beer making it through to the second round of this competition is already leagues ahead. Achieving an award is an incredible accomplishment for the brewery involved.
