part of the welcome.

What began as part of our gatherings became part of the everyday. KOSO, now available through the House.

01 / INTERNAL STRUCTURE

R’S KOSO

The ritual, with room to make it your own.

A concentrated Japanese postbiotic made from 100+ fruits, vegetables and plants and fermented using traditional methods. One full-size bottle contains 16 FL OZ / 474 ML.

16 FL OZ / 474 ML
Serving: 2 TBSP / 1 FL OZ / 30 ML
Concentrated / Multi-use / Refrigerate after opening

Drink it simply with still or sparkling water—or treat it as a pantry ingredient. We reach for KOSO in smoothies, dressings, sauces and other recipes when a little sweetness, acidity and fermented depth makes sense.

One bottle. More than one ritual.

02 / ON THE GO

R’S KOSO SHOT

The ritual, ready to go.

A pre-mixed, ready-to-drink version of R’s KOSO in individually portioned glass bottles. Made with the same ingredients and fermentation process as the Original KOSO — without the measuring or mixing.

12 bottles / 1.7 FL OZ (50 ML) each
Ready to drink / Single serve / Travel friendly

For mornings away from home, workdays, travel, or simply when convenience matters.
