Kamebishi‘s 20-Year-Aged Soy Sauce: Liquid Gold from Centuries of Brewing Mastery
Sensory Alchemy – Where Science Meets Ancient Art
"Smooth. Silky. Complex." Soy sauce connoisseur Haruo Matsuzaki inhales deeply from his tasting spoon, parsing apart aromas before taking a small sip. His eyebrows raise in delighted surprise. "Now that…is exquisite."
In his hands is a 55ml bottle of Kamebishi Brewery‘s 20-year-aged tamari shoyu, sold for £99 retail. It boasts a brilliant chestnut hue and leaves behind an interminable evaporative tail on the palate – marking it as perhaps the world‘s most coveted and expensive soy sauce.
But how does simple soy sauce, made from basic ingredients like soybeans, wheat, salt and water become liquid gold? The answer lies in passion, patience, and a production process that elevated humble commodities into one of Japan‘s most prized gustatory treasures.
We Journey Behind the Scenes into the Fascinating Science & Art of Soy Sauce Brewing
The path to soy sauce complexity begins with enzymes inside Aspergillus oryzae mold. Aspergillus cultured on steamed soybeans and roasted wheat forms koji – the catalyst for brewing amino acids and simple sugars into flavor. Kamebishi ferments moromi mash in cedar barrels for months then ages them from anywhere between 5 to over 20 years.
This prolongs Maillard reactions between soy peptides, wheat carbohydrates and salt ions. Umami intensity builds. Bitter notes evaporate. Aromatic compounds multiply. What starts as salt brine, beans and grain becomes liquid gold – bottled after gentle pressing to retain thickness and sediment.
Peer into Kamebishi‘s vast, silent kura (storehouse) holding dark moromi casks peering solemnly down at us. Take a deep breath, inhaling the pungent yet enticing aroma of ferment that clings to the thick wooden beams. The microbial alchemy happening inside these vessels is complex beyond belief – an intricate biochemical dance transforming simple organic precursors into aromatic esters, amino acids, nucleic acids and melanoidins through acid hydrolysis, oxidation reduction, ionic migration and more.
Centuries of Cultivating Brewing Excellence
Koji-making begins by cultivating Aspergillus oryzae spores on rice or soybean meal until the formation of tender white mycelium. Then it inoculates sterilized soybeans and roasted wheat inside temperature and moisture-regulated cedarwood mushi-koji rooms. Constant manual stirring over 55 hours encourages amino acid liberation by mold enzymes before combining with salt brine.
We repeatedly cycle older and younger moromi to blend multiple maturation stages, concentrating flavors. At 3 years, aromas turn sweet and rounding. At 5, deeper nuttiness emerges. After 10, sweetness fades leaving primarily umami and fermented complexity excellent for cooking. But peak elegance arrives around 20 years – marked by aromatic notes and silken texture beckoning the sip to linger.
Before bottling, we gently press liquid from the aged moromi between canvas cloths by granite weights – stopping early so richness and sediments remain as textural proof of artisanal tradition. This essence contains hundred of aromatic compounds like furfural, benzoic acid, eugenol and guaiacol formed during extended fermentation. It took decades…yet a single drop can disappear in seconds once contacting the eager tongue.

Tradition Bottled – A Luxury Experience Centuries in the Making
As our tasting concludes, Master Matsuzaki takes a moment, breathing deeply to prolong the long evaporative tail notes. He smiles. "Truly exceptional. Anyone can make soy sauce. Few can make art."
At £99 for 55ml, Kamebishi‘s 20-year-aged tamari shoyu clearly isn‘t everyday commodity. But rather than saltiness or sharpness, it captivates with roundness, resonance and romance enrobed in a lacquered gleam – a luxury gustatory journey beyond condiment into artisanal offerings dignifying Japan‘s iconic brewed staple into its most exalted incarnation.
This rarefied elixir channels centuries of terroir and technique from Kyoto artisans steadfastly safeguarding brewing wisdom refined when Zipangu was still isolated from foreign trade. One sublime sip transports us across time, back to flavors first coaxed from soybean and grain when feudal warlords battled for supremacy.
For passionate gastronomes, Kamebishi‘s lacquered liquids reward with a singular gustatory adventure – one precious dashi at a time into the beauty of patience, science and perfection. No mere flavoring, but liquid gold – priceless in vision, viscosity and virtuosity.
