## ■ Overwhelming Sweetness and a "Melting Aftertaste" - The "Fully Ripened" Shiranui, a Spring-Only Delicacy
Shiranui is a citrus variety born from two cultivars: "Kiyomi Orange" and "Nakano No. 3 Ponkan." While the official name for "Dekopon" is Shiranui, the difference lies in whether it is a registered trademark.
Generally, Shiranui (Dekopon) is required to have a sugar content of 13 degrees Brix or higher. However, the "Shiranui" released this time surpasses that with a "sugar content of 15 degrees." It is characterized by an overwhelming richness that spreads the moment you taste it, a mellow acidity without any sharp notes, and a meltingly sweet aftertaste. There are two major secrets to why such sweetness and depth are created: the unique "natural environment" of Tsunagi and a distinctive "aging process."
## ■ Three Commitments of Tsunagi's Shiranui
**① A long 4-month aging period after a December harvest. Breaking down acidity, leaving only sweetness.**
The fully ripened Shiranui is not shipped immediately after being harvested in December. Instead, it undergoes a one-month "drying cure" where it is exposed to the wind to dry.
