Yamahai, which is prepared in Kita Nishiki, is the centerpiece of Tamagawa's additive-free "Natural Shikomi" series.
By adding water to the unprocessed sake and aging it at room temperature for over three years, the color and flavor have increased.
It is characterized by a fragrance reminiscent of caramel and nuts and a pale amber color.
When heated as hot as possible, the aroma and flavor obtained through aging become clearer and more gentle.

Below is a message from the brewery.
“Yamahai's naturally brewed Junmaishu and Nuruka Nama Genshu, made in Kita Nishiki, have been our main product for many years.
Although we had high hopes for the potential of an aged version with pasteurized water, supply was limited due to demand for raw unprocessed sake and storage space issues.
By significantly expanding the storage space in the 2015 sake brewing year, we have been able to have a stable supply for three years. It goes well with dishes that use dashi (simmered dishes), eel kabayaki, etc. “

Most important thing in storing Japanese Sake, both matured and fresh, is to shield your bottles from UV ray, thus we suggest store them in places where sunshine would not reach.
Also excessive vibrations could do harm to the quality of sake and should be avoided.
In order to prevent unexpected leakage, we recommend the bottles be kept upright, or liquid surface be below bottle-cap level.

Most after-dinner matured sake, with very dark colors, could be stored at room-temperature.
For other matured sake, if you would like to keep the maturation level similar to the level upon your purchase, or you prefer very slow maturation after purchase, we suggest store the bottles at temperature level similar to wine cellar (10-15 degrees centigrade) or below.

If you would like them to mature more, you could store them at normal-to-low room temperature (15-23 degrees centigrade). Storing in you closet during not-so-hot seasons and relocate them in the vegetable sections of your refrigerator during summer would be one option.

For orders from within Japan, we will send out the ordered items within 3 days from receipt of your order, except for festive seasons such as year-end holidays and golden week.
For orders from outside Japan, please make inquiry by mail (info@1910kan.com)

    A mature aroma with a slightly sour taste. There is a hint of acidity in the aroma, with notes of cinnamon and chocolate.

    When you put it in your mouth, it feels just right, and the flavors of sourness, astringency, and umami come in order. The cacao-like scent also spreads beautifully.
    The most distinctive feature is its sharpness and handling. It doesn't leave a strong taste in your mouth, and flows cleanly, allowing the taste of your meal to flow through.
