The flavor and characteristics of sake vary dramatically depending on the region where it is brewed, as different climates, types of water and rice, and even the local food culture have a major impact on the final product.
Making sake involves using microorganisms and yeast for fermentation. Prodcuing sake in Kochi is challenging, as the climate is quite warm and humid. But for that very reason, the breweries in this region have had to refine their techniques and learn how to closely control the brewing process, resulting in high-quality sake that overflow with originality and brewers who are always up for a new challenge. For instance, some breweries once made sake using yeast that had been sent up and cultivated in space!
The two most important ingredients for good sake are pure water and great rice. While they all have different flavors, the 18 breweries across Kochi’s diverse landscapes all have one thing in common: they have access to some of the purest water in the country. Breweries in the mountains use the crystal clear water from the Shimanto and Niyodo rivers, while some along the coast use desalinated deep sea water that is filled with minerals.
The rice used to make sake has been specially created and cultivated to suit the humid climate, adding another level of Kochi-specific adjustments. Using these two basic building blocks, each brewery then adds their own special techniques and skills that have been passed down for generations to produce top quality sake.
While there are variations between breweries, many Kochi-brewed sake lines are distinctly dry (as opposed to sweet). This preference for dry, crisp sake is influenced by local cuisine, as many of Kochi’s most popular dishes tend to have strong flavors, featuring robust red-fleshed fish, such as katsuo no tataki (seared bonito) or white-fleshed fish like mackerel. Dry sake pairs much better with these distinct flavors, as it doesn't clash with them.
Sake-based liquors have become popular in Japan, and drinks using Kochi-grown citrus like yuzu and naoshichi are particularly popular for their fragrant and refreshing aroma.
