This is the Dewazakura Oka, aka (for the small size) "Sakura Boy": as an aside, the best name for a 300ml mini sake ever.
Names aside, though it's a great one, the most important thing about this sake is its incredible history and how it quite literally changed the sake world: single-handedly bringing about the "ginjo boom" which defined the sake trends of the 80s-90s and redefined sake for the 21st century.
Aptly named, Oka (cherry blossom) is quite literally an overflowing basket of spring blossom aromas. Unmistakeably floral, robust, filling a room with its scent, yet not "perfumey." I can think of no sake I'd like more in cherry blossom season. Rose, cherry blossom, lily, violet, on a backdrop of peach, strawberry melon. A bit of extra acidity gives Oka a really nice juiciness on the palate and makes it surprisingly food friendly.
If you're a fan of Kameizumi Eternal Spring, Yamagata sake, Ginjo in general, this is a classic and a must-try. Or if you're looking for a sake that speaks of Spring, the height of Portland's most endearing season utterly laden with pink and red color, choose Oka. It belongs on every picnic blanket and in every glass.
Serve chilled in a wine glass, an Usuhari daiginjo glass, or to fit the season, a glass/tin/light porcelain sakazuki.
Enjoy with Spring cuisine such as light spring vegetables, asparagus risotto, room temperature bento, tea sandwiches, first of the season strawberries and any Japanese dish with ume.
