Some sake bottles experiment with one unusual brewing choice. This bottle from Born combines three at once, muroka, nama, and genshu, each stripping away a different stage of processing to produce something genuinely raw and intense.
The Basics
| Type | Junmai, Muroka Nama Genshu |
| Brewery | Kato Kichibei Shoten, Fukui |
| ABV | Around 17 to 18% |
| Price Tier | Premium |
| Where to find it | Specialist sake retailers, limited international availability |
| Serving temp | Chilled or on ice |
Background
Each term in this bottle\’s name represents a step that has been deliberately skipped. Muroka means unfiltered through charcoal, a process normally used to smooth and lighten flavour. Nama means unpasteurised, leaving the sake fresher and more dynamic but requiring careful refrigeration. Genshu means undiluted, keeping the alcohol content at its natural, higher level. Combined, these three choices produce a sake with far more raw intensity than a standard release from the same brewery.
Coming from Born, a brewery already known for refined daiginjo brewing, this bottle shows a different, bolder side of what the same skilled producers are capable of when they strip processing back rather than refine it further.
Tasting Notes
Aroma
Bold and vivid, with ripe fruit, a touch of funk, and a noticeable freshness.
Palate
Intense and dynamic, with concentrated fruit sweetness, a firm alcohol presence, and a slightly wild, untamed character throughout.
Finish
Long and warming, with real strength and a lingering richness.
Mouthfeel
Full and weighty, with a lively, almost effervescent edge from being unpasteurised.
Best Paired With
This sake suits bold, rich dishes such as grilled meats or strongly flavoured stews, since its intensity can stand up to robust food. Served over ice, it also works well as a slower, more contemplative sipping drink.
The Verdict
⭐⭐⭐⭐ out of 5
A genuinely intense, characterful bottle that shows a rawer side of a brewery usually associated with refinement. It rewards drinkers wanting something with real punch.
Who it\’s for: Experienced sake drinkers, fans of bold and unconventional styles, and anyone curious about unfiltered, unpasteurised sake.
Who should skip it: Newcomers to sake, or anyone preferring lighter, more delicate styles.
Takeaway: Born Muroka Nama Genshu proves that even a refined brewery can brew something wonderfully untamed.
