Brewing Ingredients

As a leading exporter and distributor of wholesale brewing ingredients, we offer our clients the world's finest and freshest malt, hops, and yeast and wild strains, with quick reliable delivery and one-stop shopping convenience and efficiency.  High quality fresh ingredients bring out the best flavors in craft beer. 


The vast majority of American hops are grown on family farms here in the Pacific Northwest, the three state region of Washington, Oregon, and Idaho.  Over 95% of all USA hops and approximately 40% of the world's hop supply is grown here.   


Our mission is to connect craft brewery clients with family hop farms, to provide access to the highest quality hops and innovative hop products on a consistent basis and in a timely manner. 


McKinnon International Inc. has been sourcing hops since 1995 and our portfolio includes an extensive selection of public and proprietary hop varieties.  Hop product types we offer include whole leaf hops, T-90 hop pellets, cryogenic lupulin hop pellets, hop pellets blends, single variety CO2 hop extract and advanced hop products.  


Hop quality really matters as it takes great hops to brew great beer.  Hops are an agricultural product and throughout the growing season growers make decisions and adapt to optimize the quality of each year's crop.  At harvest time selecting the optimal picking window and the use of modern kiln process controls are essential for preserving the true to type essential oils of each hop variety.  For kilning the key is to balance drying temperature, air flow volume and hop cone bed depth to evenly remove moisture content. 


We work with breweries of all sizes so please contact us for your current hop contract and spot hop purchasing needs.
