A Guide to Sake Competitions: Kanpyokai, IWC, SAKE COMPETITION, and Kura Master

Have you ever looked at a "Gold Medal" sticker on a sake bottle and wondered exactly how impressive that is? Here's the short answer up front: a gold medal is a sign that a brewery's craftsmanship is excellent. It doesn't necessarily mean that particular bottle is the tastiest sake you'll ever drink. Sake competitions differ in who runs them and what they're actually judging, so a medal never means just one thing. This article sorts out four major competitions by asking, for each one: who organizes it, what it evaluates, and how the judging works. A brewer's technical competition, an international competition, and a competition for sake you can actually buy in stores are all measuring different things. Once you understand those differences, you can read an award history correctly when it comes to choosing a bottle.

What Is a Sake Competition? A Venue for Outside Evaluation

A sake competition is a venue where judges from outside the brewery assess the quality of sake. "Quality" here isn't some absolute ranking of taste. Treat it as a relative judgment made under a specific set of criteria at a specific moment in time. That premise matters before anything else.

Sake competitions broadly fall into two types. One type, the kanpyokai (鑑評会, "quality appraisal fair"), measures a brewery's technical skill. The other, hyohyokai (品評会, "tasting competition"), judges how good sake actually tastes once it reaches the market. The Zenkoku Shinshu Kanpyokai (National New Sake Appraisal) represents the first type; SAKE COMPETITION represents the second. Two international competitions, the IWC (International Wine Challenge) and Kura Master, take the approach of evaluating Japanese sake for overseas markets.

Another key distinction is what gets judged: competition-only entries versus sake sold on shelves. An "entry sake" is sometimes brewed specifically for competition submission, and its contents can differ from the product you'd buy at a store. This distinction matters for how you interpret an award, and we'll come back to it later in the article.

The Zenkoku Shinshu Kanpyokai: Japan's Domestic Benchmark for Brewing Skill

The Zenkoku Shinshu Kanpyokai is a kanpyokai jointly run by the National Research Institute of Brewing (NRIB), an independent administrative agency, and the Japan Sake and Shochu Makers Association. It gathers newly brewed sake from across the country each year to survey the current state of production technique and sake quality nationwide. Its roots go back to the original Zenkoku Kanpyokai of 1911, making it one of the longest-running competitions of its kind.

Judging happens in two rounds. In the preliminary round, judges score the sake's aroma, flavor quality, and overall impression. Sake that clears the preliminary round then goes to the final round, where it's rated on a three-tier scale: "especially good," "good," or neither. Sake that clears the preliminary round earns a "prize-winner" (nyusho) designation; sake rated "especially good" in the final round earns a gold medal. Gold medals are a much narrower cut than prize-winner status, typically under about 30% of all entries.

Entries must meet specific requirements, such as being an undiluted ginjo-grade sake with a minimum acid level. This is the crucial point: because sake submitted to this kanpyokai is sometimes brewed specifically for evaluation, it isn't always the same product sold in stores. A gold medal is solid evidence that a brewery has strong technical skill, but whether you can actually buy that exact gold-medal sake is a separate question.

The number of entries and awards varies by year. In the Reiwa 7 brewing year (2025 brewing season) judging, 793 entries produced 411 prize-winners, of which 217 received gold medals (figures as of the source confirmation date).

International Competitions: IWC and Kura Master, Evaluation from Overseas Markets

Both the IWC and Kura Master are international competitions based overseas. Where Japan's domestic kanpyokai measures brewing technique, these competitions center on a different question: how is this sake received in overseas markets? Another thing they share is that many of their judges come from the wine and restaurant industries rather than the sake world itself.

IWC SAKE Division

The IWC is a wine competition held in London by the UK's IWC Events Ltd, and its SAKE division was established in 2007. Categories include junmai, junmai daiginjo, koshu (aged sake), sparkling sake, and more (since category structure is revised from year to year, check the organizer's official announcement for the current lineup).

Judging is fully blind (brand names are hidden) and proceeds in two stages. Sake is awarded gold, silver, or bronze medals, or a Commended rating. Among the gold medalists, particularly outstanding sake receive a Trophy, and one of those Trophy winners becomes "Champion Sake," the top honor in the SAKE division. Evaluating Japanese sake on the same stage as wine is the defining feature of this competition.

Kura Master

Kura Master is a sake competition organized by French judges in France. It launched in 2017, chaired by sommelier Xavier Thuizat. The judging panel includes sommeliers from five-star hotels and staff from Michelin-starred restaurants, all professionals working in the French dining scene. It's a competition strongly shaped by the local perspective of how to present sake at the French table.

Only sake sold commercially is eligible, and judging is blind. Scoring uses a 100-point additive scale: 93 points or higher earns a Platinum award, and 80 to 92 points earns a Gold award. From among the Platinum award winners, judges select category-specific Jury Prizes, and from those, a single top honor, the President's Prize, is chosen. Overall, only about 33% of all entries can receive an award.

SAKE COMPETITION: Judging the Taste of Sake You Can Actually Buy

SAKE COMPETITION is a domestic hyohyokai that judges only commercially available sake, bottles you can buy in a store. It launched in 2012. Its founding idea is to let sake compete purely on taste, regardless of brand recognition or the size of the brewery behind it.

Its defining feature is thorough blind judging. Not only are brand names hidden, but the order in which entries are presented to judges is shuffled by computer. Judging proceeds through preliminary and final rounds. Recent editions have included categories such as junmai, junmai ginjo, junmai daiginjo, and Super Premium (check the organizer's official announcement for the current year's category structure). The junmai-type categories are scored on a five-point scale, and some categories are evaluated by sommeliers for aroma and flavor. The top 10 entries in each category (top 3 for Super Premium) receive the highest honor, GOLD.

Where the kanpyokai measures brewing craftsmanship, SAKE COMPETITION measures how good the sake actually tastes once it's on the shelf. That's why award-winning sake here is, in principle, available in stores as-is. That is the key difference from the Zenkoku Shinshu Kanpyokai.

How to Read an Award History and Its Limits

An award history is a useful clue when choosing sake, but there are three things worth keeping in mind.

First, a medal reflects a single point in time. It's a judgment made in a given year, at a given competition, by a particular panel of judges. A brewery isn't guaranteed to win again the following year, and sake that didn't win isn't necessarily unenjoyable. You can't simply conclude, "It won gold, so it must be delicious."

Second, competition entries and retail products are sometimes different things. Entries to the Zenkoku Shinshu Kanpyokai in particular may be brewed specifically for evaluation, and their contents don't always match what's on the shelf. A label reading "from a gold-medal-winning brewery" doesn't necessarily mean that specific bottle won anything. This point is covered in more depth in our sake FAQ.

Third, each competition measures a different standard: the kanpyokai measures brewing craftsmanship, international competitions measure reception in overseas markets, and hyohyokai for commercial sake measure everyday drinkability. Which award history is worth paying attention to depends on what you're looking for. If you want a bottle to enjoy with a meal, an award from a competition judging commercial sake is a better guide; if you want to gauge a brewery's technical prowess, look to the kanpyokai results.

An award history is just one of many ways to choose sake. For a broader look at how to choose, see our guide to buying sake as well.

Looking Up Award Histories on Ponsh

Ponsh maintains a database of sake award histories. Each record connects four elements: the competition (Contest), the year it was held (ContestEdition), the award itself (Award), and the winning brand or product (AwardWinner).

Thanks to this structure, you can trace from a brand's page to see which competitions it has won awards from, and what those awards were. You can also browse award-winners from a given competition's page. Now that you understand what a medal actually means, you can read an award history not as mere decoration for brand recognition, but as an evaluation grounded in a clear standard. Use the award history of a brand you're curious about as a starting point to find your next bottle.
