Spirited Secrets of Japan

Distinctly different from sake, and don’t you dare call it soju, shochu flies under the radar in most western liquor stores, yet is Japan’s top-selling spirit. Celebrated as the country’s national spirit, the fact that it’s nearly unknown to outsiders makes it feel like a poorly kept secret, whispered between izakaya stools while being passed around openly by patrons. Hidden in plain sight, shochu is primed for greater appreciation worldwide. Complex, storied, and incredibly versatile, I’m willing to wager that it’s the bottle missing on your bar cart right now.

Distilling the Highlights of Shochu

Shochu is a distilled spirit, bottled at no more than 45% ABV, and typically ranges quite a bit less. However, 24% ABV or lower isn’t even a thing in Japan. If you’ve seen something labeled “shochu” in California at wine-cooler strength, odds are it’s either a legal workaround or just plain mislabeling. To make things more confusing, some of it has been labeled as Korean soju to comply with the law.

Critical to the identity of shochu, it must be single-distilled. Because there’s only one pass through a pot still, every element leaves a strong impression.

Shochu can be made from just three ingredients. Some go solo while others create a blend from the full trio:

• Sweet potato (imo) – earthy, funky, rich.
• Barley (mugi) – nutty, clean, almost toasty.
• Rice (kome) – soft, smooth, slightly floral.

Sweet potato and barley together account for 95% of shochu sales in Japan, which says a lot about the national palate. It’s grounded, earthy, umami, and robust.

Koji Craft

No matter the foundation of the ferment, shochu owes its depth to koji, the mold-based starter that’s the catalyst for transforming sugars into alcohol. Shochu producers employ a whole spectrum, and the differences dramatically affect flavor and aroma, creating unique regional styles.

• White Koji Starter: This is the most common type used in shochu today. What’s wild is that it was actually discovered by accident as mutation from black koji. White koji is prized for its bright, balanced acidity and the ability to work well in both spirits and fermented foods that favor a cleaner, paler appearance, like white miso or amazake. It brings a gentle sweetness to shochu and is a go-to for distillers aiming for a crisp, clean finish.
• Yellow Koji Starter: When koji mold sporulates, it forms yellowish-green spores—these are yellow koji starters. Traditionally used in foods like miso, amazake, and shio koji, yellow koji brings light, fruity, floral notes and low acidity. While it’s a staple in sake brewing, it’s less common in shochu. It forges delicate and nuanced flavors, but is not built for high temperatures or extended aging.
• Black Koji Starter: Indigenous to Okinawa, black koji is the backbone of awamori, the bold, funkier counterpoint to shochu. Black koji thrives in hot, humid regions thanks to its high acidity, which naturally inhibits bacteria growth and spoilage. Flavor-wise, it’s earthy, spicy, and rich, full of character and perfect for deep, complex spirits with a bit of edge.

Cheers, To Your Health!

Besides being easy on the palate, shochu is refreshingly kind to your body, relative to other spirits. That’s because it’s…

1. Lower in calories
2. Additive-free by law (no artificial flavorings, colors, or added sugars)
3. Historically recommended to combat gout, thanks to its very low purine content (¡Not medical advice!)

Mix It Up

While shochu is often enjoyed straight, on the rocks, or with hot water in Japan, it plays beautifully in cocktails. Clean, nuanced, and never overpowering, it blends seamlessly into many classics. For example, in a Sour, shochu’s crisp character complements the tang of citrus without overwhelming it, offering a sophisticated balance that’s both smooth and refreshing. In a Julep, barley shochu’s nutty, toasty notes blend beautifully with fresh mint and crushed ice, giving a lighter, more layered version of the traditional mint julep. You may not think it could stand up to the strong flavors of an Old Fashioned, yet aged barley shochu is often compared to whiskey for its dark, warm, subtly smoky notes.

With shochu, the goal is not to overpower but to enhance the flavors, creating cocktails that feel refined yet approachable—perfect for those looking for something familiar but with a new, subtly complex spin.

It’s honestly baffling that shochu doesn’t enjoy even a fraction of the same popularity overseas. In 2022, Japan produced more shochu than Mexico produced tequila, and yet, many in the US have still never heard of it. In some ways, maybe that’s the beauty of it. Shochu doesn’t need to be flashy to be great. It just needs the right moment to find you, whether it’s a quiet night at home, a dinner with friends, or a curious detour through your local Japanese market.
