SHUWAN: The New Standard of Sake Vessels for a Modern Era

In a groundbreaking move, SHUWAN, developed by the Fukuoka-based company Shuwan, is challenging traditional sake drinking practices by introducing a new standard for sake vessels. Collaborating with the Flavor and Aroma Strategy Institute, Shuwan has successfully visualized the impact of different sake vessels on the flavor profile of sake, utilizing gas chromatography-mass spectrometry for analysis. This innovative approach highlights how vessel design can enhance or inhibit the delicate aroma and flavor nuances of sake.

Background of SHUWAN’s Creation

Japan's sake industry is experiencing a renaissance, particularly among younger brewers. Over the past decade, many have shifted away from the prevailing trend of polishing rice for higher grades, opting instead to preserve the rice's natural flavors. Innovative brewers are focusing on creating unique profiles, including low-alcohol varieties and the revival of traditional sake rice strains that emphasize umami and complexity. However, despite these advancements, the vessels traditionally used for drinking sake—such as ochoko (small ceramic cups) and wine glasses—have not evolved accordingly.

Ochoko tends to release aromas too quickly, whereas wine glasses can trap volatile fragrant elements, creating an overpowering sensory experience devoid of the drink's subtlety. Thus, there was a clear need for a new design that could complement the evolving landscape of sake.

The Design of SHUWAN

Built upon the principle of the golden ratio, SHUWAN features a unique elliptical body shape with a round opening, meticulously crafted to promote optimal aroma retention. This vessel’s dimensions are fine-tuned to ensure that the stimulating scents of alcohol are mellowed, allowing the nuances of sake’s delicate flavors to flourish. When filled to about half its capacity (90cc to 120cc), it provides a fresh perspective on appreciating sake's taste and aroma.

The SHUWAN has quickly gained acceptance among emerging breweries leading the new wave of sake, such as Aramasa, Hinomaru, and Kaze no Mori. Its debut on Makuake, a Japanese crowdfunding platform, garnered considerable attention, achieving 11.07 million yen in support, translating to 2,215% of its goal, with 1,149 backers rallying behind its development. This acclaim has extended to Japan's Michelin-starred restaurants and high-end bars, showcasing SHUWAN as the go-to vessel for experiencing sake.

Analyzing Volatile Aroma Compounds

Engaged with the Flavor and Aroma Strategy Institute, Shuwan conducted an analysis comparing two different sake types across three vessels: ochoko, wine glasses, and SHUWAN. This examination revolved around fruity ginjo sake and its aromatic profile.

Aroma Compound Measurement Over Time

The study revealed that SHUWAN effectively balances the release and retention of aroma compounds unique to its design, exhibiting qualities unseen in other vessels. Notably, it managed to detect base notes that enhance the overall flavor profile, providing a rich and fulfilling tasting experience.

Aroma Balance Measurement

In terms of compound volume, SHUWAN demonstrated a higher concentration of desirable esters—like isoamyl acetate (banana-like aroma), ethyl caproate (fruity), and ethyl caprylate (pineapple and apricot scent)—compared to ochoko and wine glasses. Conversely, it showcased lower levels of unpleasant aromas such as acetic acid and ketones. This indicates that SHUWAN effectively dissipates lighter, undesirable compound odors while trapping more complex, flavorful aromas, resulting in a tasting experience exalted by its structural design.

The transformation in aroma perception correlates to a potential change in taste, implying that vessel choice significantly impacts the overall flavor experience. SHUWAN provides a tasting encounter unlike any conventional sake vessel.

Conclusion

As sake gains recognition as a UNESCO Intangible Cultural Heritage representing Japan's craft culture, SHUWAN aims to unify the experience of sake and its vessel. Its design not only provides a new standard but also helps ensure that both producers and global consumers can share the same rich flavors, paving the way for a more immersive sake culture.
