Half of our flavor case never changes. The other half is designed to.
The case holds six mochi ice cream and soft serve flavors at a time. Three are constants: matcha, black sesame, and mango. They are the spine of the menu and they are not going anywhere.
The other three seats rotate. About once a month a new flavor arrives, becomes the current drop, and the rotating flavor that has been around longest makes room. Right now the rotating seats belong to Thai tea, lychee, and this month's arrival, Peach Oolong.
Some of it is seasonality. Japanese cooking cares a lot about shun, the short stretch when an ingredient is at its best. A peach flavor makes sense in July and a lot less sense in November.
It is also practical. We are a small kitchen and everything gets made by hand before we open. Every flavor we promise forever is one more thing to get right every single morning. Rotating lets us try things without stretching.
And a flavor that can leave gets ordered. People plan a visit around a drop, bring somebody during the window, and tell us loudly when they want one back.
The telling-us-loudly part works, by the way. Lychee arrived as the spring drop and was expected to rotate out. It kept selling out and people kept asking for it, so it stayed. Nothing outside the core three is guaranteed a seat, but the flavors you keep ordering keep their place longer.
The archive so far, oldest to newest: honey, ube, brown butter hojicha, azuki milk, milk tea. Some of them may come back around, and two never fully left: ube still shows up as the Ube Latte, hojicha in the hojicha lattes. The full list with dates lives on the seasonal page.
The current drop is Peach Oolong. The next one is already in the works, and no, we are not saying what it is. Join the list on the seasonal page if you want to hear first.
