About

Rooted in Alaska Since 1990

Kahiltna Birchworks began in 1990, when Michael East and Dulce Ben-East tapped 200 birch trees at their remote homestead in Alaska’s Susitna Valley.

What started as a small experiment grew over the next three decades into one of Alaska’s pioneering birch syrup businesses. Along the way, Michael and Dulce refined the craft, developed new harvesting and production methods, and helped introduce Alaska birch syrup to customers far beyond the forest where it began.

That history still shapes Kahiltna Birchworks today.

Carrying the Tradition Forward

In 2023, Hammers Family Birch took the helm of Kahiltna Birchworks.

For us, taking ownership meant more than acquiring a business. We inherited more than 30 years of knowledge, experimentation, relationships, and hard-earned experience.

Our goal is to honor what Michael and Dulce built while carrying Kahiltna Birchworks forward for the next generation. Today, we are expanding our birch harvest, investing in more efficient production, developing new products from Alaska birch, and introducing this remarkable ingredient to more chefs, retailers, and customers across Alaska and beyond.

But the foundation remains the same: the trees, the forest, and a few short weeks each spring when the sap begins to run.

A Harvest That Happens Once a Year

Every bottle begins in the boreal forests around Talkeetna. As winter gives way to spring, our crew heads in for a harvest that lasts only a few weeks.

Fresh sap runs almost clear and carries roughly 1% sugar, so it takes at least 110 gallons to make a single gallon, part of what makes birch one of the rarest tree syrups in the world.

Its flavor shifts as the season moves: lighter and floral early on, then darker and richer, developing toffee, molasses, and umami. Rather than blend the harvest together, we bottle each stage separately as Reserve, Early, Mid, and Late Run, so every bottle captures a different moment in the Alaska spring.

From Birch Syrup to Something Bigger

Pure birch syrup will always be at the heart of Kahiltna Birchworks, but it is only one expression of what comes from the birch tree.

Today, we use our syrup in Alaska birch cream caramels, brittle, and other specialty foods. Through HFBirch, we are also exploring entirely new ways to use Alaska birch sap, including Birch Brew, our fermented birch sap beverage.

We believe Alaska birch has the potential to become one of the defining flavors of the North. Our job is to preserve the knowledge that brought us here while continuing to ask what else this remarkable tree can become.
