As our relationships grow stronger with farmers, customers, consumers, and a wide range of industry partners, so does our collective desire for assured, consistent, and deeply integrated Mainstem malting capacity. Our next major step is a Walla Walla-based craft malting hub in the heart of Northwest grain and wine country.

The Mainstem Northwest Hub's positioning amongst the vineyards offers a playful interaction between wine culture and the development of grain’s own form of terroir, inspiring the potential for what hubs in other unique geographies might lend to the malting, brewing, distilling, and culinary industries.

With success in Walla Walla, we'll strive for up to two more Western hubs: Alaska Hub; Southwest Hub.

We are truly humbled by the support emerging from this wild state. So much so that we're traveling thousands of miles to meet with stakeholders from Juneau to Anchorage to Fairbanks: Grain growers, malt buyers, state government, and more. If we have the chance to put together a malting hub for your state, it would be an honor. For more info, see the memo below and do get in touch!
