From Field to Flour

People made nutritious, delicious flour thousands of years before the invention of the industrial mill. Our back-to-the-future approach is a modern understanding of soil, grain, and craft. Cairnspring Mills has reimagined the supply chain that turns wheat into flour: the land, the farmer, and the customer. Here’s how we make that happen.

Select Only the Best Varietals

We work closely with our farmers to choose wheat varietals that are well-suited to the specific regions they grow in. Every varietal is tested for flavor and performance in our soils—not just for yield or protein, the usual measures of commodity grain.

We also stay connected to our breeding network to keep an eye on what’s coming next such as new, interesting variations in flavor and color, nutrition, and disease resistance. For us, it all starts in the ground and keeps evolving from there.

Soil-Centered Sourcing

Most of our farmers come from our personal network and are people we know and trust. They are prohibited from using glyphosate as a harvest aid and neonicotinoids due to their documented impacts on ecosystems. We also pay a premium over commodity markets to ensure our farmers are fairly compensated.

We also believe in progress over perfection. We meet farmers where they are, working alongside them to improve the health of the specific ground they steward, season by season. Through our Soil Health Initiative, we support practices that build organic matter, increase biodiversity, and restore resilience to the land.

Commit to Completely Traceable, Identity-Preserved Grains

We store our wheat locally in small-scale grain silos. Each varietal is kept separate, and our wheat is never blended with commodity grain. This preserves the distinct character, flavor, and performance of each harvest.

Source Regionally, Plan for the Full Season

There are two grain plantings each year—winter and spring—and just one harvest. Because we don’t buy from the commodity market, everything that comes off the field needs to carry us through until the next harvest.

That reality asks us to plan differently. Building resilience into our supply chain is paramount, which is why we focus on sourcing grain regionally in the Pacific Northwest. Staying close to the source helps us maintain quality, adapt to seasonal variability, and stay connected to the farmers and landscapes that shape our flour.

Our Stone-Milling Process

We use European-style stone milling techniques to intentionally incorporate all three parts of the wheat berry: the germ, bran, and endosperm. The result is flavorful, aromatic, and textural flour with exceptional baking performance.

Utilize Stone-Milling Technology

We mill with stone, not steel. This slower, more attentive process produces flour with superior texture and flavor while preserving more of the grain’s nutrients, antioxidants, and natural oils. All three parts of the wheatberry—bran, germ, and endosperm—are intentionally included.

Create Clean Flour, Without Treatments or Additives

Our flours are never artificially enriched or treated. We don’t add dough stabilizers or conditioners such as enzymes or malted barley. Our flours are never bromated or bleached.

Looking Ahead: Regenerative Certification

We are actively working toward regenerative certification for our conventionally grown flours through A Greener World (AGW). This work is ongoing and reflects our long-term commitment to soil health, transparency, and continuous improvement—supporting farmers in practices that regenerate the land while producing exceptional grain.

Sustainability

Everything starts with care. We care about the land, our grain, our partners, and each other. We create a place where people feel valued, supported, and part of something meaningful. Through attention, generosity, trust, and respect, we build strong relationships and lasting impact.
