The Making of Gwahaju - A Twice-Brewed Sool

Gwahaju is not finished in a single brewing. First, a clear rice sool is made. Then, a second fermentation is layered on top to bring it to completion. This "twice-brewed" method raises strength while deepening softness - a defining technique of Korean traditional brewing.

The method emerged as a way to keep wine from spoiling in summer heat. The result is a wine that holds high strength with grace, retains its balance over time, and never feels heavy on the palate.

What Makes Gamtanju Different

Kegzei preserves the original form of Gwahaju - but redesigns two elements to bridge the century-long gap in modern taste.

First, an in-house fermentation technique was developed to refine the rougher aromatics and Nuruk (Korean brewing yeast) notes of traditional Gwahaju.

Second, to introduce a fragrance the modern palate would embrace naturally, Jeju Hallabong was co-brewed into the Sool.

Brewed traditionally with rice alone, just 2 out of 10 tasters responded warmly. The challenge: to honor Gwahaju's heritage while reaching today's drinker. The answer was Hallabong - the most distinguished of Korean citrus. With it, all 10 out of 10 said yes.

Finding the meeting point between Gwahaju's heritage and the modern palate took 1,000+ tasting interviews and 18 months of development.
