It all starts with real milk.
Before the fruit, before the flavor, there's milk. One familiar ingredient with a story that's only just beginning.
Early access Ours starts with mysa: the whey associated with Icelandic skyr-making. A familiar food. A less familiar liquid. An invitation to look again.




Before the fruit, before the flavor, there's milk. One familiar ingredient with a story that's only just beginning.

Add live cultures, a little warmth, and time. Milk gradually transforms into a thick, tangy cultured dairy base.
This describes dairy culturing, not a claim of live cultures in the finished MYSA drink.
Straining separates the thick cultured curd from the lighter liquid whey. One stays behind. The other is about to become something unexpected.

Meet acid whey. Naturally tart, often overlooked, and the ingredient that inspired us to rethink what a dairy drink could be.

We take cultured whey and give it a fresh perspective. Water, fruit, botanicals, and thoughtfully chosen flavors turn an overlooked ingredient into something refreshingly different.

Inspired by Icelandic mysa; our modern flavors are a new chapter. Get to know whey
In Iceland, the whey separated during skyr-making had a life of its own. Fermented into sýra, it helped preserve food. Diluted with water, it became an everyday drink.
MYSA takes inspiration from that resourceful idea: something overlooked can become something you look forward to.
Meet the traditionStrained dairy-making separates a thick curd from a liquid stream. Modern producers have found many uses for whey, yet acid whey can still be difficult to put to work.
We’re developing MYSA around that opportunity: give cultured whey a new role, with a lightly tart flavor direction and honey, fruit and botanicals.
Our inspiration is Icelandic. Our ambition is a first release with New York in mind. Ingredient origins and production details will be shared before release; we don’t claim Icelandic manufacture or a measured environmental benefit.
