Among all creations from Dassai, this is the pinnacle — the Dassai Shinsei Umeshu 2025. Officially priced nearly 70% higher than the already-premium Dassai 23 Umeshu, it remains a rare bottle that vanishes from shelves across Japan despite its cost. What, exactly, justifies such a bold valuation?

The answer, perhaps, is a mystery. Rumor has it that only about 300 bottles are produced annually. Some enthusiasts note the presence of the character 「磨」 (“polish”) on the box and speculate that this umeshu might share a base with Dassai Mina no Senku — the distillery’s most refined sake — though the brand has never confirmed these whispers.

Official data reveals that the next-tier Dassai 23 Umeshu uses fully ripened, top-grade Nankō plums infused into its famous Junmai Daiginjo 23%. The Shinsei Umeshu, however, reportedly selects only the finest plums — literally “one in a hundred” — from the same orchard. As for the sake base, details remain undisclosed. The only confirmed fact: this umeshu contains a higher concentration of “Dassai exosomes” (獺祭エクソソーム) — beneficial compounds formed during fermentation. Beyond that, the rest remains deliberately veiled in mystery.

So what’s truly inside this bottle? What flavor profile could justify a leap so daring in price and prestige? Perhaps only the moment the cap is unscrewed will reveal the secret behind this enigmatic creation.
