  • Next Phase: Acorn Processing

    Acorns are the single most important food stock in California.

    They are enjoyed by First Californians from coast to coast. And it was traded throughout the state and beyond. We all share this heritage, even though we have different stories, songs, and journeys.

    While the First Californians are famous for eating acorns; we are not the only people in the world who gather and process acorns for food.

    As we develop the equipment necessary to process the acorns we harvested during our First Annual Acorn Harvest en masse, we wanted to tell you more about the global significance of acorns.

    The Global Significance of Acorns

    Acorns are eaten in North America, Europe, and Asia. China is a major manufacturer of acorn harvesting and processing equipment. Their largest customer is Korea. Where acorns are a major food stock, so common that acorns are part of the pop culture.

    Yeah, I totally used TikTok as a source. “Acorn Caricature” is so hot right now!

    But acorns aren’t just a recent trend. Acorns have been a part of Korean pop culture for a long time.

    Check out this children’s book, “Kindergarten in acorn village”; which is a popular and well-known series:

    Kindergarten in acorn village (Korean Edition) by Nakayamiwa (Author), Kim Nam-ju (Author) https://a.co/d/7fKocbo

    But it’s not just Korean culture that celebrates the acorn.

    Here is an eminently relevant article published in the National Library of Medicine: “Food Security beyond Cereals: A Cross-Geographical Comparative Study on Acorn Bread Heritage in the Mediterranean and the Middle East“.

    Anecdotally: The dude at a gas station near our office gave me his mother’s recipe for Berber Acorn Bread, when I told him what I was working on. He shared with me that acorn bread was something he ate as a child, and shared his fond memories of gathering and processing acorns.

    When I brought him an acorn from a Coast Live Oak, he was so used to the sweet acorns of his homeland that he immediately opened the acorn to eat it–not realizing that this acorn is high in tannin and very bitter. But it was his experience that influenced his belief that all acorns were ready to eat, because they are in the place he’s from.

    This is all to say that acorns are global. And they are something which can tie us together when we need it most.

    Foodways are intersected by the acorn, not the other way around.

    This is why we all have an innate fascination with acorns. Because we all share an ancestral urge to eat them!

    For our purposes, we’re going to be processing acorns en masse, in an effort to produce food for as many people as possible.

    Yes, it’s true that some of the most traditional ways to process acorns include soaking acorns in flowing water.

    Most processing methods use water directly from rivers, streams, and springs.

    But we don’t have free flowing bodies of clean water anymore. We have culverts, canals, aquaducts, and flumes. And they’re full of trash, industrial (agricultural, manufacturing) runoff, and pollutants like sewage, and microplastics.

    So, we couldn’t show you how to do it traditionally, even if we wanted to. Because it’s not safe.

    Anyone who tells you different is probably gonna pull out a glass jar, or some coffee filters to process acorns in their kitchen, anyway–and that’s not “traditional”, either.

    So let’s just lay this one to rest and make peace with the fact that the world has changed [is continuing to change] and it behooves us to adapt accordingly.

    None of this makes the acorn less special, or our mission less important.

    It means that we can share our enthusiasm and celebrate the reopening of indigenous foodways with more people!

    And there’s nothing better than sharing something with people who appreciate it as much as you do.

    Modern Acorn Processing Techniques are Well-Documented

    There is an enormous amount of literature and video available for modern acorn processing techniques to make small amounts of acorn flour. Not the least of which is this cool open source zine called “Eating Acorns: A Guide to Processing Acorns for Use as Food” by Mary Hatch.

    There’s also a CSU Sacramento Museum of Anthropology Publication called “Past and Present Acorn Use in Native California”. And even cookbooks, like “Acorns and Eat’em: A How-To Vegetarian Acorn Cookbook

    We recommend this guide to Leaching Acorns by Sara Calvosa Olson, the author of “Chími Nu’am: Native California Foodways for the Contemporary Kitchen

    These are the kinds of Acorn Processing methods we will show you during our Public Acorn Processing Workshops:

    Modern, relevant, acorn processing techniques you can enjoy in your own kitchen, with readily available tools and supplies.


    While those are good for small amounts. We’re going to be processing much larger quantities.

    We are offering two types of Acorn Processing Events.

    The first one (listed above) is our public workshop. We are also running production workshops.

    Production workshops will be focused on producing the Acorn Flour and Acorn Meal we’ll actually offer and distribute to Indigenous Communities, and the Muwekma Ohlone Tribe of the San Francisco Bay Area.

    Learn more about how we will accomplish this task by volunteering to help us process the acorns we’ve harvested.

  • Harvest to Table: Experience the Flavors of Alameda’s Acorn Revival

    Discover Alameda’s Acorn Revival, reconnecting community with indigenous foodways through harvest, processing, and culinary celebration.

    The First Annual Acorn Harvest is part of a series of events by the Alameda Native History Project known as the ACORNS! Project Arc. This series was made possible in part by a grant through the Alameda County Arts Commission’s ARTSFUND.

    ACORNS! Consists of four main parts:

    • Acorn Granary Challenge
    • Annual Acorn Harvest
    • Acorn Processing
    • ACORNS! Culinary Series

    The Acorn Granary Challenge

    A series of events in the community. We invite community members to come together and challenge themselves to create an Acorn Granary, a traditional Native American Storage device to hold acorns throughout the year—but, specifically, built for the purpose of holding acorns over winter, because the Acorn Harvest is in the fall.

    Through gathering natural materials and processing them into the supplies we use to build the granaries, participants will gain first-hand knowledge and experience of the importance of access to natural materials and the challenges of preparing for winter. Community members will discover that survival cannot be done alone and that the challenge of the Acorn Granary is not one person against nature. It is about how communities come together and build natural, regenerative systems to adapt and evolve with the landscape in a respectful and sustainable way.

    When we came together in July, we came as a small group of individuals taking part in the first-ever Granary Challenge. Our participants ranged from 2nd and 3rd graders, college undergraduates, parents, and grandparents, from diverse social, cultural, and economic backgrounds. And we want you to know, that the framework of our granary was built by our youngest participants—and we are amazed, grateful, and humbled by their instinctive expertise and boundless enthusiasm.

    About the Granary

    Our Acorn Granary is hosted in the community by the Alameda Point Collaborative Farm2Market. Our granary was built using willow reeds and bay leaves donated from the Land Partners in Castro Valley, pine boughs and poles gathered locally, twine from local hardware stores, and the granary is topped with marine canvas donated from Pacific Crest Canvas.

    The Annual Acorn Harvest

    The Harvest runs from September through November. The efforts of this community-led initiative are aimed at reopening indigenous foodways. Acorns have not been gathered for food in Alameda, and much of the Bay Area, for over 300 years. Part of decolonizing ourselves, our stomachs, and the places we live, relies on reconnecting with the natural world around us and partaking in the ancient practices of this land.

    By practicing sustainable, regenerative agriculture, we are becoming good stewards of our natural world, making space, and opening the pathways to food sovereignty, healing, and wellness for ourselves, and for more than 25,000 Native American/Alaskan Native and Indigenous People currently living in the San Francisco Bay Area.

    Even though this was the first-ever Acorn Harvest announced in the City of Alameda in recent history—with a limited budget, and not a lot of marketing involved—we were tremendously grateful and surprised by the wellspring of support from our friends and neighbors in Alameda, and from our followers on social media.

    The people who volunteered with us for the Annual Acorn Harvest ranged in age from young to old and represented a large contingent from many different social, cultural, and economic backgrounds. The Acorn Harvest was truly a family event, and we were honored to create these bonds and reconnect, together, with the natural urban forest, animals, and environment we depend on, but often overlook.

    Through our community-building and sustainable practices, we helped to divert edible food from waste bins and compost piles. The acorns we did not use for food, we shared with 100K Trees For Humanity, which will germinate and plant new Oak trees in an effort “to increase our urban forest canopies, restore natural habitats, increase urban carbon sequestration capacity to help cities meet carbon reduction goals and for greater equity for cooler healthier communities.”

    Acorn Processing & ACORNS! Culinary Series

    The acorns we harvested are now being stored over winter in safe locations around the island. In the spring, we will begin processing our harvested acorns to produce Acorn Flour, and Acorn Meal, which we will offer to local Indigenous communities, the Muwekma Ohlone Tribe of the San Francisco Bay Area, and will also be used for our ACORNS! Culinary Series—featuring Traditional and Contemporary Indigenous, and International Cuisine. Our culinary series is generously hosted by the Alameda Park and Recreation Department, at the Mastick Senior Center, and will take place every Sunday in April 2025.

  • Why We Don’t Accept Acorns Collected from the Ground

    When it comes to foraging for acorns, we have a firm policy: we don’t accept those collected from the ground.

    Here’s why:

    Acorns can mold incredibly quickly once picked up; especially when stored improperly in bags, boxes, or environments with little to no air circulation. It is vitally important to prevent the spread of mold and mildew to other acorns in storage.

    Moldy acorns are not just unappealing; they can pose serious health risks, like hantavirus. Hantavirus is a serious disease transmitted through contact with rodent droppings or urine. Ground-collected acorns are often more likely to be contaminated by mold and pathogens, which we want to avoid.

    It’s important to note that 20% or less of the acorns gathered from the ground are fit enough for storage and consumption. Since we emphasize sourcing acorns for food, we have to apply a strict standard: if it’s not something you would personally eat, we don’t want it either.

    By upholding these guidelines, we prioritize health and ensure that the acorns we collect and use are safe and of the best quality.

    Let’s keep our foraging practices safe and sustainable!

  • First Annual Acorn Harvest Will Go Through November

    We’re thrilled to share the progress of the First Annual Acorn Harvest, a groundbreaking initiative that’s bringing together a diverse group of volunteers from across the local community.

    Our shared goal? To revive ancient foodways and reconnect with the natural environment that sustains us.

    Through this collaborative effort, we’re not only preserving traditional knowledge but also providing a tangible way for community members to give back and make a positive impact.

    By working together, we’re fostering a deeper appreciation for the land, its resources, and the indigenous cultures that have thrived here for centuries.

    The Acorn Harvest is more than just an event – it’s a movement that embodies the spirit of community, sustainability, and cultural revitalization. Here’s what’s next:

    • The acorns we harvest will be stored over winter, allowing us to preserve the bounty of the season.
    • In the spring, we’ll process the acorns using traditional methods, preparing them for culinary use.
    • We’re excited to announce a culinary series featuring traditional and contemporary Native American cuisine, with a focus on acorn-based dishes! Think traditional acorn mush or dumplings, acorn pumpkin muffins, and more.
    • But that’s not all – we’ll also be exploring international acorn dishes, including Korean Acorn Jelly (dotorimuk) and other global specialties. Do you have a favorite acorn recipe to share? We’d love to hear from you!

    Join us on this journey as we rediscover the flavors and traditions of Native California.

  • First Annual Acorn Harvest Begins

    Alameda Native History Project is proud to partner with our awesome and enthusiastic and diverse community for Alameda’s First Annual Acorn Harvest!

    Acorn season is upon us!

    The streets are filled with the sounds of foraging. The crunching and munching of squirrels chewing on acorns forms a surprisingly backtrack on a slow weekend morning.

    This is Alameda’s present-day urban forest.

    You may have never noticed it before. But Alameda is full of oak trees. It’s during acorn season that we’re reminded la bolsa de Encinal is still here.

    Acorns have not been readily available as a food source for over 100 years.

    The Alameda Native History Project seeks to reopen the local indigenous foodways of Alameda and the East Bay.

    The acorns we harvest together will be used to fill the Acorn Granary at the Alameda Point Collaborative Farm2Market.

    They will stay in the granary over winter. And we will process the acorns in spring.

    Some of the Acorn Flour and Acorn Meal which we will produce will be used as the featured ingredient of our culinary series. Some will be offered to local Native American Organizations and Tribes. A limited amount Acorn Flour and Acorn Meal will be offered to the public for fundraising.

    Harvest teams are forming now. You’re invited!

    We’re excited to share this opportunity with you to be a part of our Acorn Harvest Team. Whether you’re looking for a fun outdoor activity, a chance to connect with nature, or a way to help revitalize a food pathway which hasn’t been readily available for over 100 years, we welcome you to join our team!

    Here’s what we’re doing:

    • Sorting Acorns: Help us sort acorns by size and quality.
    • Harvesting Acorns: Collect acorns that have fallen from trees.
    • Scooping and Bagging Acorns: Help us scoop and bag acorns for storage.
    • Packing Acorn Granaries: Assist us in packing acorns into granaries for long-term storage.

    Sign-up using the First Annual Acorn Harvest Sign-Up Form.

    We welcome volunteers of all abilities and will work to accommodate your needs. Whether you prefer to work from a seated position or are able to assist with physical tasks, we have opportunities for everyone to contribute.

    Join us for a fun and rewarding experience that will connect you with your community and the natural world. Let us know which tasks you’re available for and any accommodations you may need.

    Support the First Annual Acorn Harvest by donating to the Alameda Native History Project.

    By supporting this project, you are helping to revive a forgotten food source and reconnect with the rich cultural heritage of our region. Together, we can reclaim the acorn as a symbol of community, sustainability, and cultural resilience. Join us in this effort to rebuild our local indigenous foodways and create a more equitable and sustainable food system for all.

    Your contribution will directly support our acorn harvest and processing efforts, as well as our culinary series and partnerships with local Native American organizations, community organizations, and tribes. We are grateful for your trust in our work and your commitment to our community.

  • Acorn Granary Challenge Produces Storage For 2024 Harvest

    What is an Acorn Granary?

    Acorn Granaries are traditional Native American storage containers used to hold foods like dried berries, rice, squash, and tree nuts…. (In this case: acorns from the city-wide acorn harvest happening this fall.) …And keep them safe from animals and the environment over winter.

    What is the purpose of an Acorn Granary?

    To store food that people needed to survive during the coldest parts of winter, when no plants grow, and all of the animals are hibernating, or have migrated to warmed areas.

    Why are Acorn Granaries important?

    Acorns were one of the single most important food sources in California [Heizer 1957]. Over winter, the bounties of California’s many edible plants, and the abundance of wildlife normally acquired through hunting, trapping, or fishing, is replaced with a barren landscape.

    This is why it’s so important to gather as much food as possible; and to protect it from water, wind, rain, and the animals–who also depend on caches to survive through the winter.

    How widespread is the use of Acorn Granaries?

    It cannot be overstated: Acorns were one of the single most important food sources in California [Heizer 1957]. Most families had an acorn granary [Gifford 1932; Fremont 1843]. Granaries were meant to hold acorns as they dried over winter, however, granaries would be kept and maintained for many years.

    How many acorns does an Acorn Granary hold?

    Some granaries would hold just enough acorns to support a family until the next harvest. Other granaries could hold “ten to twenty sacks of acorns” [Gifford 1932]. Although, there’s no specific weight or volume measurement for how much a “sack” is. Heizer (in 1957), noted that Patwin communities had granaries with a capacity of about 6 to 10 bushels of acorns.

    Several studies included dimensions of varying types of granaries made by different California Native Tribes:

    On average, the granaries were about 3-4 feet in diameter, up to 10 feet high, and at least 2 feet off the ground.

    How many acorns were harvested during the Acorn Harvest?

    The only limit to how many acorns could be harvested was dependent upon the method of collection, and how many people were involved in the harvest.

    The Acorn Harvest happens once a year, when there is a nearly limitless supply of acorns adorning the more-than 87 million oak trees which are endemic to California. [Oaks 2040]

    Competition for Acorns

    Over 100 different kinds of animals eat acorns, including (but not limited to):

    • Bear
    • Chipmunk
    • Crows
    • Deer
    • Ducks
    • Foxes
    • Jack Rabbit
    • Jays
    • Mallards
    • Mice
    • Oppossums
    • Quail
    • Raccoons
    • Squirrel
    • Turkeys
    • Voles
    • Wild Hogs
    • Woodpeckers

    Every single one of these animals would gladly take a pre-foraged “snack pack” [that’s what a bear would call it] in a season when no other food is available.

    This is why it is necessary to create: (a) a sturdy food container that (b) hides the scent of food, and (c) deters animals from eating through the container into the actual food inside.

    What are the different types of Acorn Granaries?

    Below is a list granary types–but the names aren’t official. There are no standardized names for granaries because over 300 unique languages were spoken in California.

    • Coil-type
      Acorns chill under a coil basket made from cordage. (Usually on a platform.)
    • Hanging basket
      Hung from sturdy tree-limbs, or from a frame made from lashed wood.
    • Tree platform
      Resting on platform build in the crook of a tree.
    • Free-standing
      Made with sturdy legs to resist wind, and other forces.
    • Rock-butt
      Granary resting on a rock. Sometimes stabilized by legs, or tied to frame/tree limb, or all of the above.

    Construction Materials

    Willow reeds & poles, and California Bay boughs, were gathered from the Indigenous Land Lab

    • Willow reeds and poles
    • Leaves and boughs from:
      • California Bay Laurel (Umbellularia californica)
      • Bay Laurel (Laurus nobilis)
    • Natural twine
    Bay Laurel boughs were gathered during the Acorn Granary Challenge Session #3, at the Alameda Point Collaborative Farm2Market, where our events were held.

    Acorn Granary Construction

    After learning about the history, usage, and types of Acorn Granaries, we began granary construction over four sessions in July 2024.

    Rolling the frame onto the hoops.

    Completed granary frame.

    Loosely woven base of the granary. (Take note the base is larger than the frame.)

    Granary frame stuffed with bay leaves, sitting on base base, on top of tree rounds (with willow shims, lol.)

    Shoring up the granary, using willow poles to stabilize with tension & compression. (MIT undergraduate remix.)

    Granary Status: Ready for Acorns

    Special Thanks & Acknowledgments

    A huge shoutout, and special thanks goes out to the APC Farm2Market, for hosting our event, and the acorn granary.

    Another huge shoutout goes to the Land Partners, who are hosting the Indigenous Land Lab, another Acorn Granary, and have graciously allowed us to harvest all of the willow and California Bay we used (and will use) for Acorn Granary Construction.

    Special thanks goes out to everyone who participated in the Acorn Granary Challenge: Sandra, Liz, The Li & Pan Families, Natalie, Skipper.

    We also want to acknowledge the Alameda County Arts Commission’s ARTSFUND for their part in funding this awesome, and ongoing, experience.

    What’s next?

    The First Annual Acorn Harvest begins this Fall!

    Stay tuned for more announcements!
